EBC greenstuff Beware c36

[joboo]

I purchased the EBC greenstuff from Tire rack about 1 year ago, at the same time I replaced the front rotors on my 95 C36. I was just told by the dealer that my rotors have less than 8K miles on them and they are warped beyond repair. I will now have to fork out big cash again for these rotors. Just BEWARE of these pads. I will probably be going back to the stock pads now to be safe.

I thought it was common knowledge, that EBC pads will grind up your rotors in a short time. ;)

Did the dealership ask you why you were using "aftermarket" "high performance " pads with stock rotors?

[adelaros]

That is scary.. I replace my with "Sat pro performance oem pads" and Brembo Rotors from the Tire Rack. Any coments on the history on this Pads that I should now?

Aren't the stock rotors a soft rotor style where you need to replace them with every brake pad change?

I've heard a lot of things about this green pads. That's why I stay away from it.

Green Stuff are race pads... it should be used in that application only. Pads will grind up the rotors as well as themselves very quickly

I asked the dealer if I should go back to the stock pads, but he told me not to worry about the greenstuff, that they should be fine. The dealer told me that the stock AMG rotors are supposed to be able to with stand high heat with out warping. HE told me that it has happened before to customers, that it must be a bad batch of metals in the construction of the rotrs. Hopefully they will replace them under warranty. I will keep you guys posted.

2 years ago, I tried a 'high performance' set of pads. I noticed that my pedal effort was way up, perhaps suggesting a harder compound. They stopped poorly until fully warmed up, then they weren't too bad, but not noticably better than stock. I didn't perform stopping distance measurements to say for sure. I did however perform temperature tests with an ifrared pyrometer. I did this because my new rotors warped badly soon after installing these pads. I performed a series of hard stops from highway speed, then measured the rotor temperature. I installed new stock pads and new rotors (again), then repeated the test. The stock pads allowed the rotors to stay considerably cooler.
It appears the aftermarket pads were not designed to dissipate the heat quite the same way as the stock ones. While this may improve the fade characteristics of the pads, it is death to modern, thin rotors that are designed to be replaced, not machined with every pad change. My 2cents anyway. Stick with stock on a Benz and go with the AMG rims - they're easy to clean:)

I had the EBC Green stuff on my C and they warped two sets of rotors. Initially I thought it was my fault by washing the car when the rotors were hot. But the second time around I knew it was the rotors. (I kept the second set to see if I can get a warranty replacement due to bad metal, etc.). What bothers me is that EBC Green Stuff pads are advertized at Tire Rack (if not the EBC web site) to be "soft on rotors" and more durable than stock pads.

I now use Porterfield R4s pads. I love them -- no fade, no dust and so far (1 month) the rotors are fine. However, these rotors are drilled and presumably dissipate heat much better. Also, I just installed SS brake lines. If the rotors warp in the near future I'll be sure to let you know.

Green stuff = street
Red stuff = street & track. ;)

I question the warped issue.. reason for it is it doesn't happen.. read info by respected brake company..

While they might not be the " main" source for information I think once you read up on systems and deposits you will see that this makes more sense than the rotors being warped. You would have to really put some heat in them to even consider warping them ( track use ) .. I am guessing you didnt not bed the pad correctly and thus you are not getting the performance you think you shoudl have.. always best to check and see if rotor will work with pad.. that comes with asking around... Pagid and my Brembos work great.. Other pads. Porterfields etc.. would never go on my Brembo brakes as Brembo told me what to expect.. I think as a whole EBC works good on BMW rotors and not MB ones.. having done many combos on my C 36.. stock, C32, and now Brembos. I run Pagid blue on Brembo and it works fine.. just need 15 seconds of heat and they are good. but you can destroy a rotor in minutes with improper break in.. I would guess if you looked at rotor you would see blueish deposit lines and from that point you can fix it but to do so is expensive etc.. replace the lines first and upgrade fluid.. then ask around and see what pad works well. I think that Porterfield on a stock MB rotor seems to work really well.. Pagid on a stock pad does not so well. EBC I would stay away from all together.. but that is my 2 cents.

Interesting website. FYI, I have seen warped discs. My Maserati had runout on one of almost 1/16" . It was abnormally picky about pads. I won't go into it's other shortcomings here. The pads I tested on my Benz were EBC. I really didn't like them. I did, however, bed them properly. In my 25 years as a licensed motorhead, I have built countless cars, and that's one thing I am very careful about. The best brakes I have owned were Stillen rotors and Mintex pads, also on a Benz. Damn, they were nice.

Thanks for all your guys' input, I still think I'm just going to go back to the stock pads and rotors.
