Couple of times over this last week I’ve gone to pull away and heard the rear brakes squeak off when it’s been raining heavy. Been ok today and yesterday
didnt feel them dragging. Today I’ve jacked up the rears and I can spin the wheel without to much effort but there both dragging rubbing. Both handbrake leavers come off all the way to there stops fully off position. Not sure if I need to replace both calipers or if I should just leave them for now. I’ve not noticed any burning or heat from them

another thing I’ve noticed if I rock both rear wheels back and forth as in the rotation they both knock. I have genuine pads in.
