Cars with rear disc brakes
On vehicles with rear disc brakes, the parking brake is completely separate from the main braking system.
As a parking brake, drum brakes are additionally located in both brake discs of the rear wheels. Thanks to this, the parking brake is subject to only minor wear. However, due to corrosion of the brake drums or contamination of the brake shoes, braking efficiency may be reduced.
To achieve the best parking brake performance, it is usually sufficient to drive about 300 m with the parking brake slightly applied at low speed.
Release the parking brake, then tighten the lever until it clicks a second time.
Mark the position of the rear wheels relative to the hub so that the balanced wheels take their original position when installed. To mark, it is enough to make a stroke with chalk or paint on the disk and hub.
Raise the rear of the car and remove the wheels.
In all-wheel drive vehicles with a catalytic converter: remove the screen from the front muffler pipe.
Completely loosen the self-locking nut from the parking brake equalizer rod.
Turn the brake disc so that the adjustment hole is opposite the installation mechanism.
Turn the adjusting mechanism screw with a screwdriver through the unthreaded hole in the brake disc until the brake shoe rests against the disc. After this, the brake disc will not be able to rotate.
Turn the screw back until the brake disc can rotate freely.
Install the rear wheels in accordance with the previously applied markings and secure them.
Screw the self-locking nut onto the equalizer until the rear wheels begin to brake. Both wheels should have the same degree of braking (see fig.D0046).
Release the parking brake and tighten it again. At the sixth click, there should be normal braking.
In vehicles with a catalytic converter: install and secure the screen.
Lower the car.
Tighten the wheel bolts crosswise to 110 Nm.
Make a short drive of about 300 m at low speed with the parking brake slightly applied.
Cars with rear drum brakes
In such vehicles, the rear wheel drum brake is used as a parking brake. Since the rear drum brake shoes are installed automatically, the parking brake adjustment is only necessary after disassembling the rear wheel brakes.
Raise the car.
Release the parking brake.
Pull the parking brake cable to check its free play; replace the cable if necessary.
Tighten the self-locking nut on the cable equalizer until the rear wheels can be turned by hand with difficulty.
Loosen the nut enough to allow the rear wheels to rotate freely.
Remove the rear plugs from the brake shield.
Shine a flashlight into the inspection hole. The cam of the parking brake shoe lever should rest or be positioned a maximum of 2 mm.
Pull up the parking brake lever. The brake should engage on the second click.
Install the plugs. Lower the car.
Perform a test drive and check the operation of the parking brake.
