:waving:Raise the front wheel and check to see if it is also locking up and if it is the problem is in the rear master cylinder. '83 was the first year with the linked brakes and the R/H front & rear are linked. Depressing the brake pedal applies the rear brake and through a proportioning valve the R/H front brake is also applied. If the R/H front is not locking up then the problem is with the rear caliper.Once and for all. what is the best solution to this problem.? I realize thier are a couple of cause's for it. Like mine, is this a common problem to just the 1983 year models?..
