I have recently sent a nasty letter to EBC regarding their greenstuff pads warping rotors. I have done searches and found a few posts with other people having the same experience. I want to be able to show EBC just how many people have had this problem with their product . They told me that only 2% of its customers have this problem, So if anyone can please post of their problems Id appreciate it.

 

I'm curious as to why you believe the pads caused the rotor to warp? Not a flame I just want to know.

 

Pads don't warp rotors, excessive heat is the problem...if the pads are really hot and then the car parked pad material gets transferred to the rotor and it acts like a warp. The Kevlar material transfers heat very easily that's why they work well in the cold...

Ive only driven the car on the street. I used their slotted and dimpled rotors, and they were brand new when i put them on with the pads. I dont stop fast except in emergencies, which was almost never and they warped my rotors to ****. I talked to a guy at brakewarehouse and he said their really hard on rotors.

 

Well if thats true then how come it took more than four full turns on the lathe to get them straight..if its only kevlar making them act like their warped?

 

I have been using EBC greenstuff pads. After about a month of normal driving, my brand new rotors are feeling warped. The car is shuttering when I stop. I'm going to inspect them soon to make sure they are really warped.

 

I use Greenstuff pads with Brembo rotors, everythings fine with me, maybe you just have crappy rotors, just my 2 cents

 

I'm not saying the rotors aren't warped, they obviously are if you had to have them turned. What I'm saying is pads don't cause warping, only excessive heat can do that. If the pads are holding in the heat due to the nature of the material or whatever reason, then that heat has to go somewhere and that is usually into the rotor since the Kevlar doesn't radiate heat very well.

One of the drawbacks of the EBC's is that people tend to drive much more aggressively than they did before, since the pads do provide a significant increase in initial friction over most other pads when cold. This leads to greater heating of the rotors, which are just barely big enough for normal driving. With the increased speeds and thus need to reduce those speeds, the rotors are thermally stressed beyond their limit and they warp.

 

i've had the greenstuff pads with the stock rotors and i've had not problems. i don't take my ride to the track so all the miles i have are typical street miles.
are you guys taking your cars to the track and overheating the pads? that maybe why some people are messing up their pads.
just my 0.02 cents.

 

has the same problem with the green pads. well not really. but found out in actuality that you cant torque the honda lugnuts like you think you should. they warp the rotors or cause misallignment from stresses put on the hub. this heats them up and then when they get wet makes them work. if this is too much check your wheel torque. ill betcha they are over factory specification. i now torque my own at the tire shops because of this problem. even with torque limiting sockets my wheels took over 140 lbs to break loose what should have been about 80 lbs. got new oem brembos and havent had a problem yet. for over a year.

 

I used to have EBC green with powerstops. They did warp to hell form normal driving. But anyhow I dont think my driving style contributed to it but the materials used in the pads transfer too much heat to the rotors. Plus the EBCs dont stop worth of darn either. I have since then swap back my stock rotors with AEM pads and had better performance out of them. Be warned when autocrossing AEM pads wear down rather quickly.

 

repeat after me EBC=CRAP don't use the pads, don't use the rotors.

 

heh, old news on those pads. They also shed dust quickly too if you didn't notice.

 

that's one thing that really annoyed the hell out of me. they are supposed to be dust free but it seems like they are worst than the stock ones.

 

i have ebc's on brembos....

the problem isnt warping, it's stopping on hot *** pads. look closely at your rotors, you should be able to see marks there the pad stopped on the rotor and transferred the molten kevlar to the rotor. this normally isnt a problem execpt it doesnt spread it evenly around the rotor. some say you can sand it off to a certain degree, but i can't vouch for it. just get new rotors, and dont come to a total stop after hard breaking, use the ebrake to hold the car. unless of course its an emergency..

 

ebc greenstuff=

 

what about the redstuff pads?

 

 

Exactly what I've heard. Use Axxis Ultimates and be much happier. That's what I have.
