Before I tear my rear brakes apart and demonstrate my general ineptitude in all things mechanical, let me ask the group: has anyone had the rear brakes (RR to be specific) lock when rolling backwards? At first I thought it was a problem with the parking brake, and it may still be, but I also found when not using the PB at all, when I rolled backwards a few feet the RR brake locked. I monkeyed around with the bits I could easily reach to release it, but honestly have no idea what I did. Is there some detent down there that is worn/broken/out of place? I would appreciate any head start on this repair that the group can suggest. I am driving a 1967 SV. Many thanks, Bill
Bill – Hi, two ideas for things you can check. The drum brake is a simple device. When you pull the drum off it will be obvious if something is broken – it could be something odd like the lining coming loose from a brake shoe. The second idea is that the problem may not be in the brakes but inside the differential. There could be be something loose that locks the differential gear on the RR axle shaft when reversing. Does the locking occur when the car is in neutral?
