Did I Ruin my EBC Redstuff Pads
This weekend I installed EBC redstuff pads on the front along with Stoptech drilled/slotted rotors. The first couple of miles were fine and then the front wheels started making a pulsing scraping sound. The left side was very loud, right side was not too bad. It sounded a lot like a bad wheel bearing but figured it was the pads since both sides were making sounds. Drove a couple more miles and the sound never improved. The sound also wouldn't change when applying the brakes.
I then went out and did a 60-30mph medium pressure braking maneuver. About halfway through the maneuver the pedal went soft and dropped about 1/2" then firmed up again. I stayed light on the pedal after that and went home. Upon inspection, the pads have left dark metallic deposit streaks on the rotors. The slots and holes are also filled with pad material. I have to assume this material is the "brake-in" material that coats these pads from EBC. The braking maneuver must have annihilated the brake-in material. I can scrape the material off the rotors with my fingernail, so it's certainly not permanently embedded into the rotor. I'm concerned that the pads won't break in properly now, or worse the deposits damage the rotors and cause uneven wear and vibration with time. I've put a few miles on the car with light braking but the deposited material doesn't appear to be going away. The brakes feel really good however. The pedal feel is a lot like stock without the initial bite. I've reached out to EBC for help, but no response yet. Anyone had this happen to them?

This is a blessing:
EBC pads are ruined the moment they emerge from the furnace. Or maybe when the fall out of the mold. Regardless they are crap well before they leave the factory. They only get worse when installed on a car

Despite the photos, I have to disagree. These pads are far better than stock, at least for the street. Less harsh of an initial bite than stock, but a similar stopping power vs. pedal pressure feel. And no dust or noise, at least not yet. Assuming they don't get any worse, these are better than stock for street use, in my opinion.

What you're seeing is totally normal as far as I can tell from your pictures.
Continue bedding as described here. https://ebcbrakes.com/articles/bedding-in/ |

In E90 there is not so much difference. I used their yellow stuff on track and they are good street/track pad. |

EBC confirmed what I feared. The harder than intended braking maneuver wiped out the "brake-in" material and smeared it all over the rotors. They said that I should go out and perform a normal bed-in procedure and it should eliminate the deposits on the rotors and bed-in the brakes as desired.
They indicated that its not uncommon for their customers to go out and bed in the brakes right away instead of doing the 200 mile gentle break in. The purpose of the brake-in material is to enable the customer to bed the brakes w/o having to do dangerous braking maneuvers on public roads.

Anyways, I wouldn't worry about those deposits, it'll come off eventually. You should be fine

I went out the bed in the brakes...
6 60-30 medium stops 4 60-20 hard stops 2 60-20 emergency stops (ABS activating) Each stop was separated by about 30-60 seconds of driving to accelerate to the next braking maneuver. The brakes got very stinky (think big rig braking down a steep grade smell). And indeed the deposits on the rotor surface disappeared. There are still deposits in the rotor holes and slots but I'm not too worried about that. I'll clean them out with the wire brush next time I take the wheels off. |
