Rear Brake Mystery?!
Hey all, owned my '93 75 brick for second season now, and noticed it was time to replace rear brake (pad non-existant) I was also leaking from pedal side of master cylinder (boot), so that replacement came shortly after pads. But here was my process
Ordered pads, and decided to renew o-rings and seals in rear caliper. Noticed a loss in pressure to brakes, so I renewed master cylinder piston. Bled brakes from caliper and reservoir side. rode for a 100 miles and repeated bleed.
My issue is i've noticed the pads weren't retracting from rotor completely so as I spin wheel i heard almost metalic squealing caused by outboard pad rubbing on rotor.
I can fix this by pushing the pad away from rotor with finger or screw driver- but then I lose pressure to pedal until a few pumps where pressure returns and the pad sticks again slightly rubbing rotor, causing rotor to get super super hot from any riding let alone at highway speeds.
I've disassembled, and cleaned piston cups, and re assembled, bled and re-bled, and I can't figure out a solution to this. All insight is appreciated, especially as I will probably be renewing front caliper components similarly within the next 1000miles.
Panhandling on Brooklyn Bridge for a spare clutch plate.
