Scotty do you ever use a lift when working on cars or is the jack and stands good for everything?
Also, would you be willing to let a team of archaeologists examine your garage?

Srsly man, STOP TRANSLATING YOUR VIDEOS TO OTHER LANGUAGES!!!!
“Honey, is he still out there shouting about brakes?”
“Sure is. He’s been going since 2am this time. The police came at 3 but he ignored them, then he stopped for a coffee at 5 but he’s been flat out since then.”
Hahaha this comment is under rated. I've been watching him alot lately. hes cool but I do wonder what his neighbours are thinking sometimes hahaha

I had a 61 chevy pickup with drums. It took me a quarter mile to do a panic stop. Pucker factor = 11
@Bill Hill well I have a similar truck to your's its a 1955 GMC truck with manual drum brakes all around. It just took more effort to stop then power brakes.
@@billybob042665 Same here , on my 70 duster it was dangerous if you didn't start braking ahead of time especially in the rain , when i first got it i learned that pretty quickly after zipping past 2 or 3 stop signes lol

@@jonathanbelanger6574 Stopping was an afterthought until the 80s
I remember when GM proudly declared "Disc Brakes" on the brake pedal back in the 70's and 80's
As did Ford back in the '60s.
My 86 Chevy has it as well.
My 1993 buick park avenueultra had drums in the back.
Yet, Even they (both GM and FORD) used Drums and not Disc's at the rear
Rev up your disc Brakes

Scotty, you're a straight talker with integrity. It is great to experience that rare quality in this day and age. Much of your advise and insights is much appreciated and some resonates with what I was taught 40 years ago. Keep up the good work. Your efforts are much appreciated!
I couldn't have said it better.
Scotty is the best.
Really appreciated 👌🏾
Watching this guy's channel makes me wish I had a vintage muscle car, tools, and a garage to work in. I still have that spirit in me, being from the tail end of a bygone era.
He is the man. Good upstate NY fella born & raised!
Scotty has a dream about brakes. Wakes up and does a video about brakes at 3am AND you can’t forget the shades cause those lights are too bright!
Scotty is always down to earth with his explanations. He’s a true mechanic and I love this channel.
Why did you film this video at 3 am? Did you like have a nightmare about drum brakes and disc brakes lol
He's saving his daylight for when we change the clocks.

I love how Scotty speaks to both the how (direct technical explanation) and the why (history, design choices, degree of importance, etc.) for all of these basic auto issues. You can't beat a good "Pros & Cons" video. ;)
You know I've been watching a lot of Scotty's videos in just the last year and I've learned a hell of a lot. I don't agree with everything he says all the time, but I mostly agree with what he says. And he obviously knows more than I do so I've learned a hell of a lot also.
You agree with Scott cause you are a follower! Real men are building 69 charger's in our own shop's pal...
Scotty, I remember talking about this 35 years ago in college. The professor said that if you need to stop the rotation fastest drum brakes are what you want. But to have controlled breaking or not or not to instantly stop, disk works best.
Hi Scotty, Your videos are a great mix of knowledge and humour. I have been watching your videos from India and learning a great deal about cars. Seeing your garage reminds me of my fathers garage. My father is an engineer and still has tools and nuts and bolts from 50 years ago in the garage. I wish you good health to keep doing what you love and keep producing these great videos. You are a global treasure.
You're a legend Scotty. Love your passion on explaining things. Keep up the good work. GOD BLESS!!!!
Scotty I think you are perhaps the most bull free advice giver. You get straight to the point, are brutally honest, and don’t beat around the bush. I like that in a person. I’ve been a mechanic for many years (not as long as you though) and watch your channel because you teach me things in an efficient manner and I like the way you give your advice. Keep up the great work my friend!!! God bless!!!!!!
Thank you for this incredible education, Scotty! You're like the "uncle" we all need to ask our car questions to.
Facts. I wish he was my unc.
Sucks that some people didn't grow up in a car guy family. My dad and his brothers were hot rodders or lowriders so everyone knew things about cars. Me and my buddies are all car guys. It's a fun and useful hobby to get in to

One of the best car mechanics on UA-cam...Thanks Scotty, I've learned a lot from all your videos!
Thanks for clearing this one up Scotty! I've been wondering this for a long time!
Totally agree with all of your explanations here, and I learned a bunch of new things too! Thanks Scotty!
For normal daily driving, I would even believe rear drum brakes last much longer than rear disk brakes (as those seems to rust way quicker, being used less often) .
Scotty, you have so much energy.
Ur job is ur enthusiasm
Very, very informative. Thank you very much for posting this. I was considering swapping out my rear disc brakes on my 93 Honda Civic but have since changed my mind because of your video. Thank you very much!!
Thank you for useful presentation, Scotty! And thank you for your Service, Airborne!
Hi all just an fyi Remember gas is compressible,slotted or drilled rotors are made that way to release "gas" pressure from moisture or "steam" also some brake compounds outgas when under pressure. The slots or holes give the pressure a place to escape instead of pushing back on the pads. Nice work Scotty thanks for all your videos 👍
My car is so old, its only brake is an old shoe on the end of a lever rubbing up against the edge of a wheel.

You are down to earth on cars and their mechanics. Thank you for sharing your experience and knowledge.
Thank you very much for the information, I was debating on potentially getting a rear disk brake conversion kit since I've never owned a vehicle with rear brake drums. Thanks again! 💯
Glad I saw this, only yesterday I was contemplating replacing my drums with disks. Great timed video :D
Don't lie to yourself, you planning on adding 4 disc brakes as DLC on the next NFS.
@@brunoraoni Wrong, I was planning on adding 4 disc brakes as part of the Season Pass on the Ultra Deluxe Edition™.
😳 a few persons i knew did the rear conversion ended up with worse braking performance because they didn't factor in that drum brakes provides more braking torque than disc and they needed to change the proportioning valve to compensate.. regular driving stick with factory set up
EA Games, It's In The Grave.
Scotty still says disks are waaaay better than drums *shrugs*
Thanks Scotty! Love the history of disk brakes you mentioned- very interesting stuff and it makes sense. Dealing with an old Ford truck with four wheel drum brakes with no brake booster and they stink! I like the idea of converting just the front. Thanks again!
I have to take back the "they stink" part. I've got them working pretty good- just needed to tighten them up. This is something you can mention on your master cylinder video- the fact that the brakes need to be properly adjusted at the wheel so that they drag a bit (at least for drum brakes) to tighten the pedal! Thanks again.
This was much more interesting than I anticipated. I already knew all the technical details, but the history was fun as was your presentation. Thanks!
Thanks for that info. Cleared my mind about ever doing disc brake conversation on my 2012 Civic LX. 🤙
Nice explanation. Scotty got it right this time. But he left out one of the reasons for putting drums on the rear - the parking brake. You don't want to rely on hydraulics to keep the car from rolling away after you get out of it. You want a strong, mechanical linkage to keep the friction surface firmly in contact with the drum or with the rotor. With rear drum brakes, a simple cable from the handbrake lever to the brake shoes, and another lever attached to the brake shoes, can keep the brake shoes in contact with the drum. What kind of mechanical connection are you going to use to keep the friction pads in disk brake caliper in contact with the rotor? While some cars do have some kind of mechanical connection to keep brake pads in contact with rotors, the solution for other cars is to use a combination system which has a rotor and small drum cast into a single unit, and small brake shoes inside the drum. So now you have disk brakes AND drum brakes on the rear. Now things are getting more complicated, and heavier - heavier than plain rotors would be, and possibly heavier than plain drums would be - defeating one of the advantages of disk brakes. Might as well just make the drums a little bit bigger, and dispense with the rotors.
Yep. That's why trucks that need a reliable and strong parking break have them. Trailer plus truck on a hill can cause a bunch of damage if it gets loose.
I had a '73 Peugeot 504 sedan, and it had 4 wheel disc brakes. They had a metal cam on each rear caliper that was connected to the park brake cable. The easy way to set them was to hold your foot on the brake pedal, then pull the park brake handle. They worked just fine.
I remember the Corvette disc brakes. I worked for a Chevy dealer. My understanding was that the parking brake slipped on the rear disc brakes. I never thought about the fact that the linkage might have been the reason for the change back to drums. They told us that the static friction on a disc is less than on a drum. Hmm. I bet they were lying again.
@@alext9067 i would say they are probably right about the static friction since a drum brake has a lot more surface area in contact than a disc.
My car Tata aria have all 4 Disc brakes , but handbrakes are mechanical itself , drum inside the disc is used as normal brake drum with brake shoes inside , so the handbrakes on my car are fully mechanical (drum brake) and its all wheels are discs ...got it?
I was actually thinking about going from disc brakes to drum brakes...
*...on my bicycle.*
Funnily enough, many children's bikes used something very similar to drum brakes for stopping.
I love the drum brakes on my bicycle when I was a kid. Because the screech when you hit the brakes hard. It sounds like your doing a burnout.
Why the hell u watch this video then🤣
No.
😂😂😂
Ridiculously informative. Thank you Scotty. I have rear drums and wondered why
Wow that's much easy to understand now. Your expertise make it simple. Thank you.
My 1990 Celica has all wheel disk brakes. It depended on the trim. Lowest trim level Celicas had drums. Everything else in the lineup had all wheel disks.
Yeah my 86 as well, mine's a japanese version though and every time i open the hood i get asks if the strut bar is aftermarket. Check that out too. I don't know how your generation was but not every 4th gen came with a strut bar
Yup my 01 has read drums that I’m converting to disks, mainly cause I hate changing drums. Also I’m planning on boosting later on so I’m using bigger rotors from the avensis for stopping power
My 94 as well, makes life little bit easier when changing brakes
This guy love everything cheap and base model and no looking forward to spend any $. Typical cheapstake
I'm surprised that any Gen6 Celica had drum brakes. But then I was also surprised when Scotty said he has manual winding windows on that car too. My 1994 Celica GT in the UK has disc rear (plus drums for handbrake) and of course electric windows. Alas no air con though.
My 1972 Hillman Avenger has front disc brakes, so I'm guessing they were fairly universal by then on all but the cheapest cars (MK1 Escort base model for example). However my Avenger has no servo assistance, so you stop the car with your foot. I really like that system, you get to feel the road better, but if you're expecting a dead stop when you gently touch the brake pedal, then you're possibly in for a rude awakening.
Thank you Sir, excellent and interesting information. Since I am a pilot, I really like the aircraft references. 😎
Yeah I’ve been asking this question a lot
Thanks mr.Kilmer
Another excellent explanation. Well thought out answer. Thanks for the video.
Slotted or drilled rotors are a scam. Don't go for it, unless you race the car. Regular daily driving, go with the regular rotors. I learned the hard way after spending a lot of money on drilled rotors, only - as Scotty mentioned- to have noisy brakes and a lot worse breaking distance. I couldn't return them after a week of use so my rotor and pads replacement ended up costing me 3X the price instead of going with the plain old regular oem rotors from the start.
I have slotted and drilled and they have way mot bite to them! So yes i use them as i race a lot and the thermal dissipation helps a lot and is definitely noticeable.
Perhaps if I plan on occasional track visits in my daily driver I should vent vented, non-slotted/drilled rotors.
@@FroztiProductions yeah well lets just hope you drive a fun daily haha
@@somedudeinchirons4936 It's fun to me, at least... It's a slow project. Drilled rotors scare me, I've heard so many stories of cracking.
FroztiProductions odd, because any cracking tends to be because of too much heat. The drilled holes actually help reduce the tension in the metal as well. The holes help reduce the heat of the rotor from increased air flow and help the brake dust have a place to go during use. Go with quality metal, never go to the store and get the cheapest part or go online and get the cheapest part. You pay for what you get.
Scotty reminds me of the doc from back to the future. And sounds the exact same.
Hugh Mungus now you say it... he does 👍🏼
HUGH MUNGAS WHA ? HUGH MUNGAS WHA ? ARE YOU SEXUALLY HAREASSING ME
Rev up your FLUX CAPACITORS!!!
Slotted rotors have another benefit. I use slotted rotors because I live in an area with TONS of dusty dirt roads. I found that normal discs if you don't get rain after a while get dust packed between the rotors and pads travelling at higher speeds down dirt roads. Which I've had cause a lot of brake loss. Slots give a place for the dust to go and get blown out.
Thanks for this illuminating historical and technical account on drum and disk brakes and when to execute a drum to disk conversion.
Those rear drum breaks make a much simpler system for the emergency brake setup.
Those wear discs with a drum parking brake are better they don't wear and NEVER use it for emergencies unless it's about 5 mph or less the car will spin out it's for PARKING ONLY
Drum brakes are less efficient.
@@Thunderstormworld yes they're less efficient but they make the best parking brake
@@DylanL69 not really, disc still out preforms and less hassle
@@DylanL69 Not when the parking brake is tucked under the hat of a rotor. You get the best of both worlds
I just can imagine scotty's neighbours wearing wireless headphones when watching tv.
I dont get it? Why?
@@daveschannel49 so they can't hear scotty's high pitch voice wearing them at the furthest distance possible from scotty ie at back end of the house dave haha (;-)
I love you scotty, you always do it right. Another great video! A little goofy while still factual and on point!
Great entertaining vid Scotty! Drilled discs on bikes helps with wet weather braking (pretty much the same as you said) but solid single discs like on 70's Hondas were quite bad in the wet!
I also had an old Maverick and remember having to “pump” the brake pedal after driving through deep water to “dry out the brakes”, lol
Despite knowing quite a bit about automobiles myself, I still find the need to acquire new information a never ending battle, at least i will not be one of those stuck in the past mechanics. I've learned quite a bit from Scotty Kilmer.
The good thing about watching Scotty Kilmer's videos is, if you ever go deaf Scotty communicates simultaneously with sign language.
This what i really like and love with Sir. Scotty, his logic in explanations are very comprehensive. Salute to you Sir. Scotty.
Thanks scotty, i been researching 3 weeks straight and man i sure learned a whole lot, put 18 inch after market wheels on my car $$ not cheap but i love my cars to look nice since the 80s but the rims i put are way more see through than any aftermarket rim i ever bought since the 80s and the front rotors and rear break drum looked tooo rusty and my car looks super shiny paint job/ new rims and that rust drives me crazy so i ordered 2 FRONT DURAGO HIGHLY RECCOMENDED ELECTROPHORECTIC COATED 100% MILL BALANCED ROTORS FOR RUST PROTECTION and i ordered 2 TOP OF THE LINE ACDELCO PROFESSIONAL ADVANTAGE COATED BREAK DRUMS for the rear and yeah you right if i aint racing the car and its just my daily family driver i have read you are wasting your time putting the rear as disc brakes also, so your info is spot on!!
Kilmer makes me happy that I was a mechanic in my younger years.
Disc brakes and rotors are so easy to change too i just bought a car and glade mine have front and back disc brakes.
A seeing idog oh so true
oh yeah the birds beak, cable, springs, F&@!
Not so easy on my car because Honda had the genius idea of making the front disc brakes hub over rotor. So you have to take the axle nut off first which requires a heavy duty impact driver or a sumo wrestler standing on the a breaker bar. Then you have to remove the hub, then the rotor comes off.
The only good thing about drum brakes is that they last a long time, but disc brakes are easier to change, and they stop you faster.
@@dekoldrick What the heck kind of Honda do you have? Apart from the stupid screws that hold the rotor onto the hub (which I threw away after the first rotor replacement), it's actually really easy to replace the rotors on my 2010 Civic.
Amazing! Exactly what I was looking for. Thank you :)
Quick, informative video. I love it. Came here to get an answer and I got it. Thank you Scotty!
Scotty the REAL reason your Celica has rear drum brakes is because it makes the parking brake setup more simple and effective.
I actually am working on a 1974 maverick that also has drums all the way around, did you ever do that conversion?
Thank you, Scotty. I have often wondered about why its that way.
I always get to know something new from your car mech videos because they are based on knowledge and your past work experiences with car mechanics
The rear shoes on my 05 Vibe have lasted well over 100,000 miles. The front rotors and pads were changed around 65,000 miles.
then that means your a good driver and not to aggressive. but when brakes get old and still have lots of pad left, they get hard from age and make a squeak that drive people crazy. its normal to get 10 years out of drum brakes, they tend to get rusted up inside and fall apart. so with 100,000 on it, you still might want to have them changed. and old brakes tend to lose grip because they become hard with age. like new rubber grips very good but old dry rubber slides. over time you slowly get used to having to work the brake harder, this shortens the life of the front disc brakes as they are then made to work harder. so the 2nd set of front disc brakes tends to not last as long, and always use ceramic brakes, the cheap organic make crazy noise and makes the wheels go black with organic dirt all over them and do not take the heat nearly as well. only about a 15 dollar difference for the better ceramic brakes. ceramic is for disc brakes while drum brakes will be organic or semi metallic.
Deplorable Vibes are good cause they’re literally redesigned Toyota Matrixes...
shoes tend to last longer than even rear pads on disc brakes because of the extra frictional drag created by the pads
Driving a manual adds to brake life as well. BTW most of my driving is suburban.
Your rear disc brakes will probably last 250k+ easy if your car doesn't get rust.
I always apply both brakes equally on a motorcycle. I don’t want a cement sandwich!
I use engine breaking and some front brake because I don't need to move my foot
As you should, keeps the back end from ending up in front of you.
An old guy told us years ago, when you downshift to slow your car your using engine parts, transmission parts and rear-end parts to brake with. A set of brake shoes or pads are way cheaper than any of those.
Especially when going through corners. Rode the Tail of the Dragon not long ago, used the rear brakes more in that day of riding than what I normally use in like 3 months
best tutorial.
fully explained.
coolest presentation and one with all my questions answered.
This answered all my questions. I have a 2002 Mitsubishi Lancer ES that has 14" wheels with drum brakes in the rear, and disc in the front. The drum brakes were replaced/renewed about 18 months ago. Then about 6 months after that, I was told from another shop that they are leaking, and something (I think the cylinders) had to be replaced to stop the leaks. I only put about 9,500 miles a year on this car. It's my around town beater car, and I drive it to work which is only 7.5 miles each way. It's been a great car the 5 years I have had it. Thanks Scotty
No complaints with drum brakes on my 06 Silverado. Changed the front pads, rotors, drums, shoes, and wheel cylinders at 100k miles. They were all original. Not bad for 13 years.
pughconsulting My brakes are all original too discs are fine but the drums in the back for some reason make noise when you brake below 30 KM 25 MPH so I think it’s time for a brake job
Can't stand disc brakes on the rear of a vehicle in the salty states. They rust away and seize up about 3 times faster that the front discs, so you have to replace the rears every few years! Drums are pretty much lifetime maintenance-free units that are better suited for the daily driver. Plus the parking brake always works way better on a drum brake since it uses the main shoes anyways. Love the vids, Scotty!
Driven in Canada for 20 years and only ever owned two vehicles with rear drums.
I’ve only had ONE caliper seize on me... and it was so easy to replace along with the ruined disc that I’d take it over drum brakes any day even if it had to change calipers every year. That same cheap jobber caliper and disc are still going strong after 7 Canadian winters... the other one is probably the age of the vehicle: 14 years.
Shoes also last a lot longer than pads because they have more material.
Drum brakes on oll of my cars were rusty inside and hand brake requred maintenance. Disk brakes were always okay. Audi 80 uses main disk pads for a hand brake and it is great.
so many seized rear calipers. those pins become one and weld themselves in. I find if you are a little harder on the brakes intentionally they dont seize as bad.
Pine Hollow Auto Diagnostics It’s called maintenance.
A big reason for rear drum brakes is that it is easier and cheaper to arrange a handbrake mechanism. Some cars have a combined disk/drum at the rear, the drum just for the handbrake.
I have wondered that for a long time! Thanks Scotty!
Im laughing so hard that he kept his shades on even in the dark lol.
He's the coolest man 😎
I really like drum brakes for off roading application.
No stones!!
that's why I was surprised to hear that disks are used in tanks. Drums are more rugged.
My C240 has rear disc stoppers AND rear drum ebrake. Remove disc, mechanism inside😁. Happy your channel is prosperous.
Thanks for another good one!
And, just watched your video on electronic emergency brakes (bad idea). Drum brakes in the rear make cable emergency brakes simple, it looks.
Here in the North East, discs rust so fast when exposed to road salt. I have to change discs every 2-3 winters. I wished my car had drum brakes. Most trucks use drum brakes all around and there is no problem with water or fading (unless the driver does foolish things).
Don't forget drilled/slotted rotors have a tendency to crack around the holes/slots.
That's only with the badly made ones or the rotors were modded after they were made, making fractures a real possibility. That's only a problem with generic, badly made ones, or were worn out too quickly and couldn't dissipate the heat due to being far past the car manufacturer requirements for a safe usable rotor
Ok Scotty it's obvious you are correct on this one..... but those red calipers and drilled and slotted discs look so good!!
Thanks Scotty, I had thought of changing up my 1985 Olds Cutlass to 4 wheel disc, after watching this I will stick with the 2 n 2 as currently the stopping control works ace, and I can respect that I was being swayed by a salesman. Thinking about it no more, maybe swap out the old rad though... for an aluminum one ?
When he mentioned the Maverick I smiled
My first car was a ‘75 Maverick, disc front drum rear, non power, learned to plan my stops real quick 😂
My first car was a maverick too!
I put slotted cross drilled rotors on my car cause the regular rotors I use keep warping. Probably because I use cheap rotors but the cross drilled rotors on Ebay and cheap and work well.
Probably just needed breaking in to stop the warping. Which involves speeding to about 50, hard brake without stopping then speeding up to 55,60,65 doing to same thing about five times. Then let them cool down for about half an hour.
High chance your warping is from mismatched tightening of your lug nuts. It really makes a huge difference. Use a torque wrench when tightening lug nuts to ensure they are all exactly the same tightness. I used to get warped rotors on my cars all the time until i realized to use a torque wrench, ever since, no more problems. Last set of new rotors going on 3 years now, no warp or pulsing
I put power star drilled and slotted rotors on my ram 2500 and they gave me a huge improvement with breaking. High toe heavy horse trailer often and coming down some steep California grades, I can build up a lot of heat in my brakes. I recommend drilled and slotted discs for pick ups that are hauling heavy loads and going down Steve grades
Omg!! I had a 1972 Maverick. I really miss those days! Bad brakes but It still my favorite car I ever had. It was my first. It was such an incredible feeling! Age slowly sucks the fun out of everything.
if you change just the front brakes to disc there needs to be a proportioning valve installed for the rear brakes.
Even cars with 4 wheel drums have proportioning valves as during braking there is a wheight transfer to the front so they do most of the work, regadless of being drum or disc.
not always true. my 67 chevrolet heavy duty half ton van did NOT have any proportioning valve and it would lock up the rear brakes first if the truck was empty or lightly loaded. not a great thing but that was life with older stuff.
Yeah... that’s when American vehicles were “unsafe at any speed”
400+ cubic inches of displacement and nothing but leaf springs, drum brakes, and bias plies to reel it in.
@@Bartonovich52 I don't know exactly why leaf springs would make a car dangerous. Many american cars had 4xcoil springs from the late 50's on. I imagine you mean that the rear solid axle was dangerous, but it isn't really, it may provide less exciting handling, but it a lot more predictive than the snap-oversteer caused by the swing axles used on many Euro cars at the time.
@@MrTheMiguelox Agree, many Saturday night short track cars along with vintage racers still use solid axles and leaf springs. Although, unlike some internet jockeys those people actually know how to drive.😁
I drove bike for a long time. I use rear break first then front break only if I want stop faster.
GREAT information! Thanks Scotty!
You are so direct and honest on your vids, love the vids
I drive a semi truck, and to this day all trucks and trailers in the USA come with drum brakes. Some people convert to disk, but almost all of the 80,000 pound trucks still use them. And we have to be aware of brake fade, especially when coming down a mountain! But despite all that, proper use of the engine brake will keep that from happening.
Stab braking and all that jazz. Roll that coal brother. 10/4
Didn't the Kenworth T-600 or 660, in 2005 or so, come with disc as an option on the steer axle? Worked at a dealer and seen a couple new ones come in with them. Still used #30 cans and some type of wedge system vs s-cam? , but I left before I worked on one.
I work on super chassises and other truck components as a part time gig, and honestly, drum brakes make sense in a semi truck situation, especially when the brakes are actuated by compressed air rather than fluid. And plus, they're quite simple to replace and get to when doing wheel seals.
I've heard going down a mountain, you hold your brake pedal for 3 seconds and let off then do it again a bit later.
@@patcallahan1050 I think so. I had a 2019 Cascadia with disc brakes on the steer axle, but everything else was still drums
There is one advantage with drum brakes. They are self energizing. That is that the leading shoe of the drum brake tends to wedge into the drum when applied.
But wouldn't that also depend on if the drum brake was a servo or non servo
@@thefuzzypickle8277 whether the brake is servo assisted or not, it is an inherent trait of a drum brake.
Only on one side of the brake has this effect unless you have twin pistons or cams that are linked which is a then called a twin leading shoe system
Not really a good thing. My old civic with rear drums would lock easily in the back in the snow before my front would. They were a pain to adjust. Hard to drive with confidence.
Good video. Enjoyed the history lesson.
One issue, info seems to be at odds with another video where Scotty recommends drilled rotors as a worthwhile modification.
I was looking at buying a 75 AMC Pacer today and they've got drums in the front, thanks for the info about em!
Don't forget, another reason they used them a lot in the past is that parking/emergency brakes were cheaper and more reliable(for the time) with drums...
Thankfully the GT-four Celica received disc brakes on both front and rear.
My European 1.8 had all disks too from factory. I guess it's an US thing on the Celica
Hans Wurst ikr, I live in the Caribbean and we got all the badass Japanese cars since we drive on the same side as the UK. The USA didn’t get any of the good cars.
I WAS JUST GOING TO DO A REAR DRUM TO DISK CONVERSION ON MY CHEVY EXPRESS VAN. THANKS FOR THE INFO JUST SAVED ME 500 BUCKS.
Back when there were many disc front drum rear configurations around, was the fact that drum brakes are self assisting. This was useful for the functioning of the emergeny brake system as the e-brakes used the rear brake drums /shoes and could be mechanically engauged as was done using a small e-brake pedal or hand lever. On 4 wheel disc brakes back then, Corvettes, Volvos etc. 1960 and 70's the emergency brakes where a completely separate drum brake subsystem that was designed into the rear disc brake hat on each rear rotor. Worked well but lots of parts so costly. In the 1990's, to solve the cost problem of a 4 wheel disc brake system with emergency brakes, the designed advanced into the cam driven calipers where the e-brake function could then be incorporated to use the rear disc brake pads/rotor to also function as e-brakes. Mechanical tolerance control and mechanical advanatge was the challenge that was solved.
Based off all of Scotty’s vids look for:
4 wheel disc brakes
Chain, not a belt
Toyota or a good brand
Manual trans
😁😁
2 wheels disc brakes btw
The perfect vehicle has already been made and its a 1994 Toyota Celica. Save yourself the trouble don't even worry about anything else.
Ive been selling auto parts for almost 2 years now and a customer told me drums were far superior then i asked why arent higher trims offered with drum brakes? Well he was an older gentleman but i did not argue and agreed with him. Thank you for shedding some light scotty!
ummm higher rims??? you mean larger in diameter wheels??? well they do use drum brakes on bigger wheels such as old farm tractors, giant huge 8 foot high wheels. and the big semi trucks use drum brakes. now yes a semi truck may have front disc brakes, but for stopping power where more pad to metal contact is needed, drum brakes have more contact surface. so they are better for stopping heavy loads. but semi truck drivers also adjust the drum brakes every time they go out on long trips. its just a simple adjustment, no need to take the wheels off on them, its just a screw, in 2 years of selling parts, you have a very long way to go. do you know why ceramic is better than organic for disc brakes. and what happens to organic pads??
If drums aren't actually better, why do heavy diesel trucks all use drum brakes.
Sep596 Odds are, the customer is one of those from the 'everything was better in the good old days' mindset. You usually can't reason with them, and you did the right thing by just sending him on his way without argument.
My only guess would be that disc brakes almost need vacuum boosting to get enough mechanical advantage to work well where drum brakes can work as good as they're going to with basic hyrdraulics or even just a cable.
@@ExaltedDuck NEED vacuum assist? Depends on the vehicle. I've a few front-disk vehicles without assist - notably a '77 F100. Yes, it took a little more effort, but not a whole lot, and I got used to it real quick. I've had a few Chevettes and Pintos with unassisted front discs, too. Then there was my old Mercury Monarch with its optional 4-wheel disc brake setup ... with a frackin HYDROBOOST. All you had to do was look at the brake pedal funny and you were instantly in a four-wheel skid.
Great video, love you vids, however I am a landscaper and pull a trailer in Chattanooga, TN and I started with just regular disc breaks and rotors and after losing breaking going down signal mountain I would suggest anyone who tows anything for a living to get drilled and slotted rotors and change them ever other year. For less than $150 generally you will get much better breaking.
to be honest u r the best youtuber i ever seen! subscribed liked and did hit the bell for the first time in my life xD
9-21-2019 - - - "Twang !!! " Hey, where'd that spring go???
I just stick my foot out when I want to stop
I take my shoe off when I do this
LOL
Fred Flintstone style. Lol
Fred? Hey, it's Barney here!
I don't need to.stick it out, I've got holes in the floor. Is your car rust-free then?
Scotty as usual another enjoyable video 😎👍 , I always assumed that lower powered cars would have a front disc/rotor and drums on rear
And sporty/performance cars have discs/Rotors all round , as with my own car , it’s a high performance model and it’s got discs all round as standard ,especially the front ones , they’re huge behind my factory 18in rims 👍
Awesome history lesson. Thanks Scotty.
