You put one of the old brake pads for the piston to blow out against. 😊
I start with both, just to keep things controlled
Omg we make dollars not sense 😂
@@auk7150 Well, ok look at the labor time to rebuild a caliper, & the markup on a reman caliper. What works to your advantage? Sometimes you might be surprised.
@@user-mx7xd4pk5h I’m for rebuild and acknowledge the point , but why not use the old pad , what’s the point of creating a more dangerous work environment ..
@@auk7150 Well, the object of this video is to not put your hand on the piston & blow it out with air. But if you are going to use air, you want the piston to come completely out, or I do, it is all to speed up the dissemble of the caliper. Sure, put a towel over it. Safest thing is to get reman calipers, so you don't dissemble them. It is ok for a doit yourselfer, but for a garage, it makes more sense to replace them, & rotors.
Small block of wood wrapped in a shop rag is what you needed
Tobey Maguire saves the day again!
👍👍👍
He'll put some dirt in your eye, atleast his eyes are covered 😂😂😂
I’ve always just used a small board never had any issues
Dang right🎉🎉
Or put your hand there to slow it down. That's why you got 2 of them.
I lost this tip if my finger in a pneumatic clamp whilst working as a machinist when I was 18. Air and hydraulics are very powerful and won’t bat an eye at body part they will go through it.
I used to be a apprentice machinist and I remember holding my finger in the chuck and almost pressing the pedal to see how tight it would feel, I was one iq point away from turning my finger into mush.
Why is Tobey Maguire breaking things with my break calipers 😂
I learnt this the hard way😢
well you don't know English well so I'd say your IQ matches your decisions. loooowwwwwwwwww quality.
El video es de lo más explícito!!! Jamás poner la mano al tratar de sacar el pistón de la pinza de freno usando aire comprimido....hay que poner un taco de madera que amortigue el impacto de su salida. Muy buen video que ayudará a no cometer un grave error.
Saludos desde Santa fe, Argentina.
Bienvenido. Gracias por calificar el video. Hola a ti también desde Kyiv, Ucrania.
Try a 2x4
What he said 2 / 4, but we no longer rebuild them. We just buy them rebuilt.
Thank you for the advice!! I’m about to do a brake caliper repair, I’d probably hurt myself!
Just fold up a rag like every decent tech has actually done
I simply remove the brake pad and pump the pedal till the fluid pushes out the piston
Piece of 2x4 usually works well…or 1x2 on smaller calipers.
Quad piston calipers are always fun.
Use fluid pressure to slowly push the piston out.
I had to watch it twice to see, that this was a pencil and not a hex 😂
Tony hawk’s a mechanic now 😂😂😂😂
For many many years I simply wrap the caliper with a shop towel and it will catch it.
Best to wrap cloth around it to both capture the piston and any mist and brake fluid also to dampen the piston from hitting the other side.
I have a hand pump that is made to calibrate pressure gauges up to 600 PSI. One piston took 400 PSI to pop out.
We used a piece of wood so you don't scratch or ding the piston.
2x4 works great
tried my fingers once. only did it once…
Try not blast the air through and control it slowly and you don’t need half your tool kit to catch the break cylinder .
That's good to do it immersed in a bucket with water... so it doesn't bounce around and can hurt someone...
Or, or, hear me out.... push the piston out bfore detatching the brake line. So break line free, snug it up, press brake pedal, remove line and pison using your hands so nothing gets damaged and no one gets hurt.
i like how he was already prepared with the safety goggles on, he knew what was coming.
Surprisingly, you can also use a bike pump if you don't have an air compressor. But definitely use a block of wood to stop the piston from flying.
You don’t need so much pressure. Just enough to get the piston moving.
Yeah it does that when you cant regulate the pressure. You might need 20 to 30 psi to get one to move out in a controlled but not forceful manner. Makes a pop but doesnt harm anything. I wrap a couple rags around it so the piston doesnt get damaged.
On a different multiverse, spiderman was a mechanic.
Would check out since it's a form of engineering.
For all those who cannot seem to understand the point being made in this video.
He first stuck his hand in the caliper, Then waved "no no" So he then used a pencil and 2 sockets to show the force that the piston makes when it comes out, And how it would demolish your hand
Yes, thank you, that's exactly the point of the video 👍👍👍
Я брал очиститель карбюратора и надевал уплотнитель. И он потихоньку выходит . на месте приора
Maybe turn the pressure regulator on your air compressor down a little.
Я обычно ветошь кладу , и удар гасит и не вылетает
А не проще убавить давление. Недавно вот только менял поршень, ставил 2 бара и чуть нажимал на пистолет, и поршень не превращался в пулю
Just use the brake fluid pressure to get it almost all the way out. Then you can remove the caliper and pull the piston.
Don’t shoot air into your caliper when your fingers are in there, good advice, I don’t know how you’d accomplish that anyway
Maybe don’t use full pressure when doing that instead.
Well, that’s one way to get 6 weeks vacation. It’ll be a painful 6 weeks though.
I use to pack a rag in front with caliper facing down and slowly let air in and it didnt hit the deck.😊. I just buy new ones now..
A hundred ways to do this, and that's not one of them.
You can buy a small hydraulic cylinder to do this with a pipe adaptor , use a block of wood between the piston and the caliper body to save damage
That's funny. I built one years ago out of an old Electroglide front brake master, a chunk of handle bar and a steel plate base. With a flexible brakeline with adapter fittings on the end. Use it for bench work on all sorts of cylinders. It will nicely blow apart most calipers.
Have fun.
No body repairs them we just replace them nowadays
Use a hockey puck it won’t damage the piston
Try bike tyre tube. Reusable and less mess cut to length
Use the brake pedal on the car. Before disconnecting.
Unless you shop at The Bone Yard.
This might not have come off my car it might be a used one I'm rebuilding.
None the less, you don't need 150 pounds all at once. A bleed valve on the airline will allow this to come apart real smooth without any drama. Our shop specializes in the older stuff. We do a lot of parts refab.
Have fun.
A longer piece of 2x and hold the end and nothing to chase and pick up👍
I use a piece of wood. I cracked a ceramic piston with the pad
When did Toby Maguire become a mechanic 😂
Most good techs have pcs of 2by in all sizes, and then you can ease into the pressure inst3ad of full throttling the shop air
Try turning down the air pressure
Good explain !!!
Thanks a lot
Dont use compressed air on brakes. Use a grease nipple in the place for brake pipe and use a greasegun to taje out the piston safe and unhurt. Its only fools that use air but the greasegun have usually about 600 kg / squere cm in presure. I start with that when i shot my cap of ny haed with the piston.😮 work safely😊
I wouldn’t want to break my pencil!
I broke my finger doing this, a painful lesson!
Wow I see alot of people have gotten hurt because you use to much air pressure and don't use a sponge to reduce the piston to hit and come out fast just saying I did this for years and never got hurt in my 35yrs experience
I keep a 3in 2x4 for it.
His spidey senses were tingling
That's good advice. Thx.
You're welcome
“Let me borrow your pencil real quick”
👍😀
Unless it’s a rare or collector car it’s easier to just buy rebuilt lol
Use a bit of suitable flat steel bar instead
And half an hour to find the pieces!
Push with hydraulic, not pneumatic.
Tobey Spiderman should grab it 😅 .
You’re better off just using a bunch of rags that way you don’t damage the piston. What do I know mechanic 28 years here
Nobody ever uses safety goggles in real life 😂
They forget, but you have to wear glasses 😊
R u sure thats the easiest way and safe? Thanks for the advice
I showed this as a precaution to avoid damaging my fingers. Using high air pressure to install the piston seal can cause injury to your fingers.
make the air pressure less??😅😅😅
Yes, you can reduce the pressure, but you need to control this process
@@opelservicekyiv какой процесс? Надо контролировать? Давление?
@@samsungsamsung-qc5uu давление. Можно легонько нажать придерживая, а можно на полную и вылетит так что потом и не найти
@@opelservicekyiv ну это и козе,понятно
You don't need to hard dump 150 pounds into it. You can bleed the pressure on smooth and easy, and the piston will slowly fall out. Use a disk pad to catch it, no harm no foul. Look like a pro, not a newbie running around trying to get the piston that just got a big ding in it out from under the work bench.
Have fun all.
Thank you
Ive seen the results of using something fleshy to stop a brake piston
Learnt it the hard way😂
Good demonstration, good warning. Also I like that bench vise, looks good and solid.
Thanks a lot
I just hold my hand over it and let it hit the end and pick it up. Never failed.
Very good call! Easy way to lose a finger.
Always use a block of wood
Wood works great
Оппа, спасибо, вы сохранили мне пару лучевых, планирую пойти в ученики автомеханика
I know someone that really did this!
When i tried it, air didnt do anything. I had to attach a grease hand pump and pump em out
Вот именно - я себе так знатно палец прищемил - чуть не сломал. Поршень, зараза, не выходил - клинило , пришлось крутить щипцами и по-разному, вот он в итоге и выстрелил чуть мизинец не снес.
Yeah because I'm always shooting air thorough brake cylinder when I'm working on it😊
People shove a shop rag there all bunched up. its safer and catched the piston with no mess
I always just put a piece of 2x4 in there
When you unbolt it just hit brakes it'll come out.
or adjust the pressure to avoid pushing tha piston in that manner 🤷♂️
and rags to catch the piston at the pads location
looks good advice to me. Salute from England! 👍🍺🇬🇧
We salute you too, thank you😊👍
I just make the customer buy a new caliper
Good advice
Thank you
~3" dia. Piston= 7.068 square inches.
~90 pounds per square inch shop air (and ill bet its more like 130 psi)
7.068square inches(90psi) = 636.17 pounds of force. Im sure with an imperfect seal on the inlet port the actual number could be less than half of this
Idk. Maybe you need a thicker pencil?
Yes, judging by serious calculations, yes. A wooden block will help
Use one of the old brake pads
I wear a ww2 era navy divers rig when I do mine.
Well yeah, if you want to have fun! Otherwise a piece of 2x4 would be ok.
Just put a rag in and done use full power from the airline. I do it, not had any issues.
I use a small piece of 2x4
Simply clever
This is why I have a hand pump with swappable fittings in the shop 😂
Good thing our hands aren't made out of pencils!
😂😂😂breaks a pencil every time 😂😂😂😂
2x4 or get a put valve on the gun and then you can slowly get it out
RIP IF FINGERS😂
