On my 69 GTX, under standard braking conditions, when I apply my brakes (both EASILY or hard and it doesn't matter on the speed), my right rear brake will lock up (even when applying minimal pressure). It does let go if I remove my foot from the pedal, but will lock up again if I so much as touch the pedal. I have an idea as to the problem, but would appreciate an unbiased response from you as to the issue, AND the repair. FYI, the brake system was gone through just 6000 miles ago and the rear shoes look good (and even) on both sides.
