I have a 1996 Buick Century. The left rear brake locks up at mostly random times but occasionally when I switch from reverse to forward. While driving Im able to free it for maybe 10 minutes by repeatedly switching from Drive to Reverse. Its then only rubbing slightly but minutes later I’ll get out on the freeway and it starts completeley locking up at 60mph! (Which at that high speed has no effect but smoke a helluva lot)
The problem is that I tried to bleed the brake to relieve the pressure but that didn’t work. With brakes bled and valve closed, I cranked the rear brake pedal numerous times and suddenly-releasing it, hoping that that would jar it loose, but to no avail. Switching gears with car running only freed it slightly, but required too much muscle to budge it. I slipped a tire iron between the lug threads and was barely able to turn the wheel around, but that didn’t jar it either. Hitting it with a hammer all around the whole drum STILL didn’t jar it loose!
Am I gonna need a 10lb sledgehammer or are there other techniques to force that drum off?
