I have a 91 isuzu trooper and the front passanger disc brake is locked up. If I let it set for some time it will free up but when I step on the brake, it locks up again. Any idea what the problem may be?
Loosen the steel lines at the master cylinder when the brake is locked up. If it releases, we gotta talk. Hopefully it will not. Open the bleeder screw or loosen the line at the caliper. If that lets it release, suspect the flex hose. If it is still sticking, it's the caliper.
