yes sir its squealing everytime whem im not braking. then if i brake it stops and sometimes the brake pads just stocked up. and doesnt return to its proper clearance. the pads just bite the disc and dont let go. so the problem is the bike cant run and the brake clamp is heating too hot. i think the master brake pump right over beside the right drivers foot peg has problem. any idea how to service it? like opening it?
