Hey blunt, how do you like those new fancy BMWs again?

Its made in Germany so you know its good stuff.

qft.

I guess the money grabbing whoreish mentality has finally made its way into the quality of EU products

So I actually read the thread.
It's not BMW or Brembo's fault, the problem is the backing of the pad has little releifs in them for cooling. These releifs aren't matching up to the pistons on the 135i's brembo caliper as the aftermarket pads for 135is are cut porsche pads. Once the correct pad will be sold for the car this problem will disapear;

OE Brembo stuff not the same as aftermarket Brembo ....

Stick to single piston stuff like the ///m boys use.

I have done countless brake jobs on "Northwest Youth Corps" Ford vans and I have seen hundreds of pistons that looked like those, some much worse.

Now keep in mind these vans go down 6% grade (or more) hills for miles on end. The fuckers that drive these things apparently don't know how to use gears to limit speed downhill.

So this tells me it is a heat issue. When aluminum gets VERY hot it kinda disintegrates into a shower of sparks. Sounds like some better brake cooling methods should be utilized for track cars and other HEAVY braking vehicles. Maybe some kind of cooling fins on the caliper (if area permits). I dunno, just an idea.

Personally I love doing brake jobs, I have done thousands of them so I have seen it all when it comes to brakes.

Also, a caliper hanging up will cause drag/friction and of course that creates heat, lots of heat. Better lubrication on the caliper "sliders" will help from brake dragging, and when I say "better" I mean better heat withstanding lubricant.

In my opinion it doesn't sound like a manufacturer issue, just a cooling issue, think about it a little, IT'S A FRICTION PART, IT GETS HOT, COOL THAT SHIT PROPERLY AND EFFECTIVELY.

My 2cents

The heat issue makes perfect sense, in fact that type of thing isn't all that uncommon with aluminum as others have said. I do find it funny how quick people are to assume it is a manufacturer problem though.

Calipers and pads are meant to reach very high temps, which the manufacturer should foresee when designing the product. Someone blamed the recesssed holes on the back of the plates. The holes are not for cooling, they are simple holes used to make the pad compound stick onto the backing plate. Many pads are like that and they don't brake pistons.

Indeed it is either a design or manufacturing process. Car is powerfull, heavy and meant to be tracked as most other BMWs. No other BMW had such problem before, even after hard track use. Just to show that aluminum pistons shouldn't be used on hugh performance calipers. There must be a reason is real competition calipers use titanium or stainless calipers, often with vented two-piece pistons.

The Bremmmmbôz on the 135 are just cosmetic and certainly not up to the task they look like they were made for...

Hey Vince! ShamWow!

Seems like someones rush to get "track" pads on their 135 cost them a little bit more money than waiting for correct ones to come out.

Interesting what happens when you try to rig something up...

yeah but wouldn't the fact that the piston's surface area is not equally applied to the pad cause a stress point and an eventual crack under hard use? I'm pretty sure the releifs match on stock pads..

et caca prout si j'ai pas raison.
