A few days after the last cold spell and road sprays my rear passenger brake started grinding when comimg to slow stop and I think I can hear it a little when taking off after press the brakes. I haven't had time to take the wheel off but the rotor looks good and at least the outer pad looks ok. I'm guessing the caliper is sticking? If it is besides stealers who carries ST brake parts in the GVRD? Need to do it fast as paying $30 per day to drive my Bronco is cutting into my beer funds.
