1967-1982 Corvette Parking Brake Adjustment Procedure

parking brake installation

*** With the parking brake mechanism in the released position cable tension measured on the front cable immediately in front of the equalizer should be between 40 and 43lbs. With the correct cable tension the handle will start to move when a 10 to 12 lb. Load is applied in the second finger grip location on the handle. With the parking brake mechanism in the 14 notch applied position the handle load at the second finger grip will be 80 to 85 lbs. ** ** To obtain cable tension, tighten nut 3B then hold nut 3B and tighten nut 3A to specifications.

Mandatory Parking Brake Burnishing Procedure.

1) With the car on a roll test rolls and rear wheels driven at 50 mph. Apply parking brake until a light drag is felt (10-12 notches on handle).
2) Operate for 55-60 seconds
3) Return brake handle to released position.

While I’m sure there are few that have a roll tester, the same can be accomplished by driving the car. ┬áIf you don’t burn in the shoes they will not hold.
