Drum brakes
If the brake shoes have been replaced or new drive cables have been installed, the parking brake only needs adjustment. The parking brake cables must be installed in a certain way to ensure automatic adjustment. If the rear wheels are not installed, if the parking brake lever is to be used in the normal way, do not adjust the clearance as described below, as this will only tighten the cables and will not make any adjustment.
To check the cable adjustment, jack up the car completely and place it on axle stands. Now the drive cable balancing lever is visible from the bottom of the car (see illustrations 17.1 and 17.2). In both cases, loosen the lock nut. On early models, loosen the middle rod; on later models, loosen the adjusting nut. In both cases, the cable should be completely free.
17.1 Adjusting the parking brake on early models. The lock nut (1) secures the adjusting rod
17.2 Adjusting the Parking Brake on Later Models (drum and disc brakes). Loosen and tighten the nut (1) again
Remove both rear wheels and check the operation of the adjusting mechanism by turning the toothed segment (1) to release three or four teeth (see illustration 17.3). Make sure that the cables can move freely and that the parking brake lever (2) on both sides of the vehicle is against the brake shoes.
17.3 Automatic adjustment control (see text)
From the underside of the vehicle, tighten the adjusting nut or middle adjuster of the parking brake rod until the parking brake levers (see illustration 17.3) move away from the brake shoes if the handbrake lever in the passenger compartment is set to position 1 or 2. They should remain in this position if the lever is switched to the second position.
Tighten the locknuts (1) and reinstall the brake drums. Ask an assistant to slowly press the brake pedal several times. During normal operation of the adjuster, if the shoes are pressed against the brake drum, a ringing sound will be heard.
Apply the parking brake and make sure the rear wheels are locked. When the parking brake is fully released, the wheels should turn without dragging.
Disc brakes
The drive cables are adjusted in a similar manner to those on vehicles with drum brakes. The location of the drive cable balancer corresponds to that shown in Illustration 17.2.

Check from the inside of the caliper that the handbrake lever rests against the stop. Without moving the drive cables, tighten them using the nut (1) until the cable ends rest against the lever. Set the handbrake lever in the passenger compartment between positions I and 2. Tighten the adjusting nut again so that the lever moves only when the parking brake is set to position 1 - 2.
Make sure the wheels lock when the parking brake lever is pulled with normal force. The wheels should rotate freely when the parking brake is released.
