My Driver rear disc is clean and smooth, but my pass rear is all ground up and it makes grinding sounds.
I’ve been driving on a 2000 mile roadtrip and don’t have issues with alignment or getting up to speed on the highway.
Weve been on some dirt roads. is it possible sediment got caught between the pad and rotor?
