How many miles are on your Gen2 Volt ? The car should'nt need brakes (pads nor rotors) for well over 100,000 miles if you're driving it normal. Regenerative braking should take care of most of you deceleration needs.Anyone done rear brakes on their Gen 2? My rotors are pretty deeply scored, although there is plenty of pad left, I'm looking at replacing them. I was curious if there is anything special to know about the rear calipers with the integral parking brake motors?
On my other vehicles with EPB the system is identical to a manual parking brake, just has an electric module to pull the brake cable. Not sure if these Volt calipers with individual motors are the same, or if some reset/recal procedure is necessary, or if that can be done DIY.
I question how you could have scored rotors yet "plenty of pad left" ?
RU sure you're not just seeing surface rust due to lack of friction brake use?
