After installing new cobalt gt pads today, there is a slight drag that can be heard at low speeds (even without braking). I think it's coming from the front and rear on the driver's side. Only thing I can think of is that the piston may not have been retracted fully. Does it need to be retracted flush with the caliper? (which the fronts definately were, but one of the rears was a PITA and i may have just retracted it to where the caliper fit over the pads). The car rolls freely when pushed by hand and the brakes feel great. No noticeable drag felt while driving.

Also, there is some squeaking at low speeds when braking, which I expect is normal with a high performance pad. Installed with oem backing plates and anti-squeak grease.

 

Did you do the high speed stop/start bedding process on them?

Here's a good link

Yeah, did the bedding process that cobalt recommends twice. Last one was late last night so hopefully it will feel better this morning.

 

It was a little better this morning, the noise wasn't as pronounced. Might try the bedding process one more time.

 

Pulled a wheel off again and it looks like the rotor is definately warped... the noise pulsates from the rotor not being uniform. :/ Anyone ever experience this?
