Well, it has been two weeks, since I had the Stoptech Street Performance brake pads put on the car.
Stoptech Street Performance Pad (Front) Review
Since then, there has been major (to me) development that I would love to get community input on. Since replacing the pads and rotors, I think that there may be a root cause for the pad deposits that was not previously considered in all cases. For the record, I do not use brake hold or my parking brake on level ground in places such as my driveway (where the events below happened).
I have a truck that often acts as my daily driver so the Stinger sits a few days without being driven. After an uneventful day driving the Stinger around (very relaxed scenic driving), my wife and I came home and I parked the Stinger for 3 days. Yesterday (3 days later), when I went to drive it, I put it in reverse and heard a pop from the front of the car and then the car started moving backwards as expected. I drove a short distance (100yds) and then pulled back into my driveway to investigate the "wiiisshhh, whiisshhh, wiisshhh" sound that corresponded with the rotation of the wheels/tires. Both front rotors had a brake pad shape "deposit" that looked like it was slopped on with a wet paint brush. These left and right side "blotches" on the rotor surface were rubbing the pads as the car went down the road making the "wiisshhh" sound for every revolution of the tire. After determining where the noise was coming from, I took the car out to see how permanently the stuff was "baked" on and did some aggressive braking to try and wear the stuff off. This resulted in "thud thud thud thud..." sound and vibration until the car came to a stop. By doing this a few times, I was able to remove the majority of the blotches, but the brakes now still pulse just like they did with the stock pads deposits. I drove the car off and on over those two weeks with no issues until this happened.
This leaves me to think something unavoidable has happened. I think that it is entirely possible that this issue has nothing to do with bedding procedure, driving style, pad composition, brake hold at stop lights, etc. because these are all things I was VERY aware of and have been careful to observe, account for, or avoid since the swap. My new pads were STUCK to the rotors in spite of all of my precautions.
Is it possible that the reason this brake issue has happened to some and not others has more to do with the "setup" of the braking components and less to do with the components themselves? Is it possible that the pads are not fully retracting from the rotor surface on all cars for some reason? Is there something that puts pressure in the line when the car is turned off that puts the pads on the rotor surface? In my case, the pads were on the rotor surface after I parked following an uneventful day of driving. Up until that point, the brakes were performing as desired. I turn the car off and leave and then the brakes start eating themselves after 3 days....
