BMW brakes on fire!! What is wrong here??!! (2018)

- Hello dear viewers!
A different video from us than usual, please read the following text.
To start off we would like to say that APEX Auto Magazine conducts investigative journalism whereby the tests are done with professional and calibrated equipment. These tests are performed by highly educated professionals with years of technical experience. What also must be said is that all of the cars viewed in this video were made available by BMW Nederland, the importer for the Netherlands, so no cars from a dealership or otherwise.
The footage in these videos show that there are significant differences and problems with the brakes of different models from BMW.
APEX Auto Magazine is publishing this video in the common interest of the consumers that buy these cars. After conducting the brake test of the BMW 330e PHEV a while back we discovered serious shortcomings that resulted in brakes that got white-hot and eventually caught fire. Brakes that turn red are very hot and are acceptable with these tests, but white-hot means that their temperature lies well above 800 degrees Celsius and self-ignition occurs with due consequences.
APEX Auto Magazine introduced the braking test some years ago to show that braking with a (fast) car is of equal importance or perhaps more important than accelerating. Where most car media aim purely at acceleration times: 0-100 km/h, 0-200 km/h etc. But a car that drives this fast must also be capable of braking hard without any problems. And that is the reason why we do these tests. The braking tests we do are done with cars that drive 200 km/h or faster and not just only BMWs, but also models of other brands with fast cars.
Braking is done with maximal force (with reflex-action and around 100 kg pedal pressure) with the car at a speed of in between 200 and 275 km/h whereby full use is made of ABS, brake force assistance, stability systems and other assistance systems that are used in an emergency brake situation.
The measurement in another BMW (540i) also revealed a braking force of up to 1.4g which is 0.2g to 0.3g higher than is usually the case.
The M4 CS even became very unstable during the braking tests. At a speed of 220 km/h the car started to swerve making counter-steering necessary which you can see clearly in the footage. This indicates uneven braking force per brake-unit and we’re talking about carbon-ceramic brakes here!
APEX Auto Magazine at that time tried to start a conversation with BMW Nederland, but after we showed the brakes catching fire on the BMW 330e PHEV the reaction of the Product Communications Manager of BMW Nederland was in our eyes quite stoic and reserved, the person in question put the problem in our hands which is of course not realistic. What also was said was that one can never drive that fast in the Netherlands, which is of course nonsense, just cross the border with Germany and you can drive as fast as you like. In short: the blame was on us. How the internal communication within BMW Nederland has been about this problem is not known to us. But what was indeed ‘urgently’ asked of us was to change the way that we do these tests, but of course we didn’t comply with that request.
Sadly, we don’t get any feedback by BMW Nederland about this problem.
Thus far our report about this subject.

Haha “why are the brakes melted.....”. Yeah it was Factory option.
only driven once after replacing brake pads
What we have learned from that is that friction cause heat.

SAAAAAAAAAMEEEEEEE HAHAHAHHAHA
Goes 250+ kmh and asks us why the brakes are glowing after braking hard
how about on fire? compare this to other cars brake tests and you'll see that brakes that catches on fire isnt that normal lol
@@Simon-rg7ly it just means that these brakes produce so much friction and according to that much heat, that the car is very good at breaking
@@Simon-rg7ly because every vehicle had the M brakes attached, and the more heavier 330e did not. Thats probably the reason why.
then why make cars that go 250+ km/h if the brakes can't handle it?
@@dokterkarel nobody said that they cant handle it. They are just not made for such extreme braking but this doesnt mean that they cant handle it. The m brakes Just have better cooling for braking several times hard in a row
So an organic pad experienced non sustained fire under extreme emergency loading. Good job. 10/10 video. I learned so much. I also learned that friction causes heat.
Organic for real
I tell you what's wrong here. 3:01 going 270km/h on winter tyre that's rated for 240km/h
you totally right haha
those are R rated tires which means 170km/h max. He exceeded that by quite a bit smh
Shit I just realised I was doing 260 and never checked my tyres ratings... Although since they come with the car, I suppose they do the job the car is intended to.
@@schniggolp2795 R19 means radial tyre for 19" rim
i have winter tyres H(210) and regularly hit 250km/h for few seconds, btw tyres are inflated 0.2 bars more than recommended
Driver like: "Boring night drive. Lemme out and light a cigarette"
Brakes : "ok"
Bravo for the camera men who running while filming the tire
The problem is everyday break pads that are nowhere near made for going 250-0, if you get high performance pads with a much higher operating temp then they will be better, but will perform less in normal driving situations
he is testing with m sport calipers. I think the problem is not with the caliper. The disk is cheap i think
@@ediz1797 Nah it isnt.
Ne diyo firat turkce anlat😅

those are carbon ceramics my guy they cost 1.5 k
May I tell you that it is extremely stupid and dangerous to stop in the left lane of the Autobahn just for "testing" the brakes?
And it is no problem that they are glowing, as long as they don't fade...
Just in general, an "Auto Magazine" doing brake tests on a public road? These fuckers are unimaginable.
usually fire means fade, the brakes get so hot, that the brake fluid starts boiling, altough i dont know what kind of fluid they use
you are just another pussy moral apostle who over dramatized this situation. empty autobahn with no vehicles, when there was one he passed by with 250kmh and I bet he didnt do this right after an overtake. after that he accelerated within few seconds on normal speed.
And never go to 0 km/h
@Jasper c 2:25 I see he never stops entirely yes
This is actually video about how awesome BMW brakes are
Actually every circuirt drivers are saying the opposite
@@TheBli7krieg not true. where do you take that information from?
@@maxgg8415 from this video. braking perfomance was bad
Awesome? Did u see that M4 counter steer? OR THE SUV BRAKES LITERALLY ON FIRE?!
You expect no fire when two metal plates rub against each other at high speeds? Car stops,brakes work,they didnt fell apart.
2:51 look how the glowing part is reversed on second test.
First test glowing in the middle part of the disc, and second test exterior part of the disc is glowing.
I think, it's time to change some parts...
A: dude youre tires are on fire
B: ik yeah theyre bmw's
A: no i really mean theyre on fire
B: oh ... lemme floor the gas
That's actually pretty cool, thanks for the video!
Emergency stop was called Emergency cause that what u need in Emergency,those breaks save ur life u dont care about a destruction at this time....
car catching fire in emergency situation is just another deadly hazard
it should not be happening
the brake pads are not suitable for this car, they can't handle the heat
the reason they went for those is to look better on paper than competition - lower braking distance at speeds below 50kmh
flames might be caused by contaminants on the disk and edges of the pads. it could also be if they were recently installed and there is exposed residue of lubricants and copper lube on the pads / calipers - they can catch fire too.
Very gut work
Wtf do you expect that happens if you do a hard stop to 0 when going 220+ or 250+ also very good way to warp your rotors
so when you're on track, or have to make an emergency stop at very high speeds, you better don't brake because you might warp your rotors? If your car is capable of going 250+ km/h, I would expect it to be able to brake from 250 km/h aswell. Not trolling or trying to be a wise-ass.
@@dokterkarel i mean doing it time after time in a short period of time
@@boostedone1367 you mean like, on a track? All those cars have big calipers and thick rotors to disipate heat.
@@mehmetkara2752 not every car. Track days some people come with bone stock cars
@@mehmetkara2752 The calipers an rotors used on these stock cars like shown in the video (M4 and stuff) already are huge.
How much time passed between each of the two braking tests for the cars?
This is still very good. Try an E430 before the Facelift, where still could fit 16inch wheels. Breaking that from 250kmh is an adventure, let's say it like that
what do u mean dude??
@@metin7480 that this is a very good and sufficient result and just mentioned another car that doesn't perform that well.
@@no-damn-alias i understand but what ur saying is a bit weird those cars are like 2016,2017 and the car u say is older and no need to say e430 or e300 the brakes are same
@@metin7480 yes I just want to say, that there's no reason to complain. Sidewalls are already small enough on modern cars and there's no reason for an even bigger compromise on this. In my opinion we reached a good point between sidewalls and brake size
2:33 damg he almost lost control
Thats not allmost lost control. Jesus man you shoulnt never have the drivers licence i you think thats on the edge off loosing control
The 540i discs don't glow even after that test. Looks like the Msport brakes held up well. Glad to see that cause have the same brakes on my M140i.
СУПЕР тест))
I think the 330e brake is a bit on smaller or less sporty set up. Hybrid cars expected you to use less physical brake and more regenerative brake, so they give you less physical brake. See F1 rear brake compared to non hybrid F1. (6 Pot vs 4 Pot)
That's not true. My Activehybrid has 340 mm discs. Is that insufficient?
i usually hit brake in controlled conditions and car can make some uneven braking but esp/abs work perfectly and keep car to go where steering wheel is pointed
The fire in the last clip is actually the brake pad catching on fire. All the other clips are just the rotors heating up to their limit. This is always conflicted with the pad type/characteristic and the speed which stopping from. Any race type pad is gonna heat up the rotor immensely. Especially at higher speed. Triple digits. And multiple high speed stops will put so much heat into the rotor if it's not cooled down properly or long enough this is a result. I personally think there test were successful and the cars did well. They all came to complete stop under very hard braking with glowing rotors. Anyone who understands vehicles and has some understanding of basic science will see this as a success. This is why you don't buy cheap pads or rotors.
Great succes, safe cars
Pads should not set on fire, period
* slams emergency brake from top speed over 200kph *
wHat iS wRoNg HerE ?
The video has taught me that the 4-piston BMW Brembo brakes do not catch fire in emergency stopping from 250 km/h while the 1-piston brakes are catching fire when emergency braking from high speeds.
and here is someone that never understood friction
UA-cam : Wanna see some vehicle break ?
Me : okay.
330e likely has lighter brake discs and is designed for regenerative braking. That doesn't happen at maximum deceleration.
Maybe go for the carbon ceramic brakes rather than standard steel brakes, of that is an option? It might help, if you do track days, etc.
Nice test.
Thank you!
@@ApexAutomagazine did you finally got any statement from BMW NL or DE ? (Aside 'its your test thats in fault'?)
Curious if the same issue is present on the 530 hybrid
hi wich type of brake has 330e in the test ? first equipped disk 312mm or M performance 340mm ? i have 330e and i thik that i have smaller disk , 312mm for my car
That 4 series coupe was sparking because lf brake pads... And brakes heat up when they are used obviously hence the discs glowing
Thats BRAKE HORSE POWER on fire 🔥
In case cabin lighter doesnt work. BMW has your back ;)
3:54
roses are red
violet are blue the time stamp u were looking for
is 5:00
very nice video , but what i see with all the brakes is that all of the cars don't use there full surface of the caliper. like when the pads are worm crooked. or the disc it self is warped. the smaller surface of where the brake does grab makes allot of extra heat. i don't know if this is normal. but i thought that there would be a consistend line on the brake pad surface when the discs gets hot enough the radiate light. ( could also be of the ventilation of the disc that you get these 2 glowing rings instead of one ) but for the last test i would think that the thickness of the disc is just barely enough to make that stop safely ( of course an emergency brake at top speed is not very common )
Because the disk needs air refrigeration.
holy crap the 3 seris catches fire
One thing is wrong here is surface color diffrence bracking bricks are from my perspective not regular that making heating in certain places on top on bottom but not in center
For BMW M4 CS,
at 2:56...look at the area of disc thats turned red in the 1st test
at 3:16...now look at the area of disc thats turned red in the 2nd test.
Intelligent stuff. Different areas on brake discs on operation on different occasions. Helps in managing brake temps better! WOW BMW
Thats because most of the brake pad faded away. This is a brake failure its NOT good nor some sort of technology lmao... What you should be seeing is the entire disc glowing not just parts of it. A good example of that can be seen in the Bugatti Chiron Titanium Caliper brake test video.
Dude! That's how Brakes work. By braking, you generate friction, and friction generates heat. The brake discs when are glowing red, are over 500*. The fire is caused by the material in the brake pads that is on fire.
If your brakes are glowing don’t stop because you’ll warp your rotors. Keep that airflow moving if you can.
What happen to 330e PHEV? Lower brake pads quality? The brake caliper catches fire immediately after emegrency stop. The others just glowing disc but not catches fire.
Breaks have to bake during hard breaking...its normal...in fact with carbon ceramics,the hotter the disc,the firmer it holds
that just for brake with race material, normal brake will lose its performance when reach about 200-300 degree
Make this test again but with 3 brands. Bmw 5 series, audi A6 and mercedes e-class.
Similar specs. 3.0L diesel with 250hp. Maybe som other brands too.
You need to keep carbon breaks clean. My friend tracks his F80 M3 and he has a procedure before every track event. Every breaks will catch fire if driven hard enought, but the fire with 330e was suprising becouse of all the sparks comming from break pads. That really looks like inproper breakpad material.
I love glowing break discs waaayy to much
Whats the background song?
Ceramic brake rotor has a nature of burning but still retain brake force.
Cảm ơn bạn chia sẻ ,tốc độ và phanh
Difference between classic style breaks and carbon ceramic I guess... :P
The Lubrication grease gets ignited by those Temps.. not great not terrible
Nothing to see here, this is just some premium flames.
whoa ! YIKES !!!
As far as I know its a characteristic of Titanium brakes, similar to Buggati Chiron
HM have anyone tried puting thermal paste between the break disk and the rim? Because that is going to be a great way to transfer quickly a lot of heat away from the break disk.
only I noticed that the camera is very static, even at 300kmh?
nothing wrong.
just go to sleep and do not drive, you know nothing is simple.
Or respect the speed limit
The brake components on the 330e were most certainly not stock, either the rotors or the pads (or both) have been replaced with low-quality parts. It's quite a shame that these were apparently cars from BMW's own fleet which means they're very likely to be used in other tests (car magazines etc.) as well. Probably not the best way of advertising your products :D
Verbaast mij echt hoe jullie dit op nederlandse snelwegen hebben gedaan
Güzel video :D
It’s nice to see you guys think about braking too instead of just flooring it. It’s a shame that BMW Nederland reacts like this (maar niet vergeten t zijn hollanders hè, die mensen zeker van bmw geven geen fk om remmen), but this should be showed/put to light to BMW in general. Perhaps if you guys do that they would try to find a solution to this. And at last thank you for this very informative video!
PS If you ever test the braking of a lamborghini, lmk
Brake pads fault. They just can't stand high temperature. Many fxx series even with sport blue calipers have changed pads to ferodo ds2500. M4 standard pads are ok to 240 motorway but not hard braking and not tracking
EVERYONE GANGSTAR UNTIL THE FLAMES REACH THE PERTOL TANK
I have the m6 grand coupe its an exotic
Bro you are like fucking 11 you may have a bike if you're lucky
weight ?
Were this dude recording this on a highway? Looks like it is
What I'm curious about is, if the PHEV brakes did catch on fire due to a stop, would they cause a fire if the car didn't move immediately, wind extinguishing the fire? I mean Brake lines and DTC lines are covered in plastic, wouldn't they be melting after like a minute?
Don't drive with components on fire, hoping the air will extinguish the flames 😂 stupidest thing I ever heard.
Cool
premium brand
Wondering there's a huge truck behind this car while he doing this.
This behaviour is completely normal, what did you expect to see.
In fact all those BMW cars featured in your video performed very well in the emergency braking test. You should try a Toyota Corolla or a Hyundai, you’ll know what poor brakes are really like.
Weird... Almost like friction causes heat or something? Hmmm
270km/h, full emergency brake and you ask why the brake glows? Idk you tell me. I gues the car is moving very fast.. and then a sudden pressure was put onto the brakes.
やっぱ、BMW・Mシリーズのブレーキは高性能だわ......
260 to 0 brake mean fire
damn its actually burning.... But it is still unclear if its enough to actually set the tire on fire.... And looking at it it feels like ABS/break pad sensors should be fried and there should be break pads/abs faults seen on your dash screen....
What’s with all the heavy sparking when 1st applying brakes?
micro parts from brake paddles. is just normal things. plus probably is normal pads so is not so eficient for braking like that hje need some race padles for that
Guys, brakes on fire is only talking about the last video. That 330e, why?
Will doing an emergency stop on BMW's like these warp their rotors?
Maybe, it's hard to say... but metal is fairly resilient to heat, as long as there isn't external forces acting on them while they are hot. Cool them off, as safely and slowly as you can which minimises the contracting forces of cooling
Whenmthe 330 drove off the air from the wheels speed made the flames go out
Got Mercedes Benz 240-0 max. braking test? Let's see how the Star brakes perform...
Like shit
Me: looks at 2nd BMW speedo
My brain: I paid for the whole speedometer so imma use the whole speedometer
@Pharmaceutical Grade lol
We learn out of this that the 330e (last car) has to small brakes for the weight it carryes.
It need much bigger brakes so they dont heat up tjat much to light the brake pads on fire !!
I have the 330e. Changed the rotors out, rebuilt the calipers and upgraded pads after a few trips. The originals always drag the rotors, cause insane amounts of dust, and feel spongy at high speeds. After upgrades, 100% difference. I wonder what the rotor temps were before braking.
@@jasonspink1981 I asume hotter rotor temps than the other one's for sure !
And if you say that the stock brake system on yours was junk then we know for sure why they caught on fire in this video !!
hi wich rotors do you use on your 330e?i must change mine standard rotors now
Its all fun aand games until your plastic intake manifold is on fire :P
Alternative tittle: Friction causes heat.
M6 has carbon ceramics and thats the way the heat up so thats normal
1:48 woow this beautifull!
BMW : ignites a fire in your soul
UA-cam : absolutely
The 330i has single caliper brakes just as any other normal car, except unlike most cars that have FWD, the 330i has a 50:50 weight distribution so part of the load goes to the rear which is better. Also the rear discs are ventilated unlike Fwd cars. Even so the front rotors are usually larger than other non premium manufacturers use. The pads depend on what you want to use. Stock ones are very good.
The m4 has high performance calipers and pads that are far superior to single pot calipers and stock rotors.
Audi and Mercedes use in general better brakes except Audi doesn’t benefit from the weight distribution advantage.
In this video the 330i either uses some bad pads or it is normal to happen. The brakes designed is not the issue. I did a lot of braking from 200kph to 100kps on the racetrack and no issues with my z4 ...same engine and brakes. Braking from 220kph to 0 is harder than racetrack use. After braking hard it is better to drive the car for a little while so that the rotors cool down a bit if possible
Weight distribution doesn't play a part here because of weight transfer to the front during braking. Moreover, most German premium cars have near 50/50 weight distributions, not that it would make a difference during braking though…
It doesn't take a high performance brake to catch fire I was trying out some new pads on my 01 cherokee and from 110 to 0 they caught fire lol. No I don't normally go 110 in an XJ but lol damn it I want my brakes to work no matter what happens.
Don't do 110 in a Jeep then, even if the sign says so
End now e36 m3 ,e46 m3 en the makina e39 m5
Das ist normal 👌
Die Scheiben sind dafür ausgelegt ein paar mal 250-0 zu schaffen aber dann war’s das auch
What you have learned us today is you don’t understands brakes at all. If you completely stop from 250 to 0 calls for some rotor warping. Never stop from that speed, especially while generated to much heat !! Just sad watching that 😄
Soo where is the problem?
This is no problem , if you want to brake from 270 to 0 like everytime you drive then get a car with good brakes , but if you drive normal like to work and such than you dont need that so the brakes on the cheaper models arent so good but still good enough that if you have an emergency at 270 km/h you will stop safely
hi poster,im bmw dealer from china.I wanna use your brake test video clip to my video,would you mind? waiting for your sincere response~！
