Vehicles before change point in 1982 ADJUSTING PARKING BRAKE Note: The parking brake system, which is entirely separated from the service brake, is only subjected to limited wear since it will not be used for normal driving. This reduces the coefficient of friction, e.g. from brake drum corrosion or liner contamination. The force required for application of these brakes will increase to the same degree. To reach an optimal effect from the parking brake, it will normally be sufficient to drive max. 400 meters (1300 feet) from the parking lot to the working place with the parking brake applied (lever pulled until resistance is felt and then one tooth further), before adjusting the parking brake. | |
A requirement is that both parking brake cables move easily. Parking brake needs to be adjusted, if parking brake lever can be pulled up by more than 6 teeth. Push up rubber cap on parking brake lever. Unscrew locknuts (1). Unscrew adjusting nuts (2). | |
Unscrew and remove one wheel bolt from one rear wheel. Turn tapped bore to be 10° past the perpendicular in clockwise direction. Turn adjusting nut with a screwdriver to move out parking brake shoes that brake disc can no longer be turned. Then turn back adjusting nut by 4 to 6 teeth. Adjusting nut turned up = tightening. Adjusting nut turned down = loosening. Brake discs should turn easily. | |
Pull up parking brake lever 4 teeth and adjust adjusting nuts (2) until rear wheels, left and right uniformly, can still be just barely turned. Release parking brake lever and check whether wheels can be turned easily. Tighten locknuts (1). | |
Vehicles after change point in 1982 ADJUSTING PARKING BRAKE Note: The parking brake system, which is completely independent of the service brakes, is subjected to only limited wear since the parking brake is not applied in normal driving situations. Consequently the friction torque drops, e.g. because of brake drum corrosion or dirty liners. The force required for operation will increase proportionally. To reach optimum efficiency from the parking brake, normally it will be sufficient to drive the car form the parking lot to the workbay with the parking brake applied (pull lever until resistance is felt and then one catch further) max. 400 meters (1300 feet) prior to adjusting the parking brake. | |
A requirements is that both parking brake cables must move easily. Parking brake must be adjusted when parking brake lever can be pulled up by more than 8 teeth. Lift off brush cover plate (1). | |
Unscrew adjusting nuts (2). | |
Unscrew and remove one wheel bolt on each rear wheel. Position each tapped bore approx. 45° behind the perpendicular. | |
Move out parking brake shoes by turning adjusting nut (1) with a screwdriver until the brake disc can no longer be turned. Then back off adjusting nut 4 to 6 threads. Turning adjusting nut clockwise = tightening. Turning adjusting nut anticlockwise = Loosening. Brake discs must turn easily. | |
Important! If adjusting nuts are hard to turn, take off rear wheels 36 10 300. If applicable, remove brake discs. 36 10 300 | |
Pull up parking brake lever 5 teeth and turn adjusting nuts (2) until the left and right rear wheels can just be turned uniformly. Release parking brake lever and check, whether the wheels can be turned easily. |
