Parking Brake - Checking the Free Play

Running gear maintenance: Parking brake - Checking the free play of the parking brake lever

Parking brake: Checking the free play of the parking brake lever

- Checking the free play of the handbrake lever.

The parking brake has asbestos-free brake linings.

NOTE:
- The handbrake with asbestos-free brake linings must never be adjusted in such a way that the lining must grind down during operation!
- The handbrake must be adjusted if the handbrake lever can be pulled up by more than 4 teeth with medium force application (without a braking effect)!

Adjusting the parking brake

1. Remove the rear wheels.
2. Undo the parking brake lever and push back the disc brake pads of the rear axle until the brake disc can rotate freely.

NOTE: To make the turnbuckle accessible, open the cover of the tray behind the parking brake lever and remove the rubber inlay and also the insert.







3. Undo the adjustment nuts -arrow- on the turnbuckle until the cables are without pretension.







4. With a screwdriver -Figure-, turn the adjustment device through a wheel bolt threaded hole so that the brake disc can no longer be moved.

NOTE:
- The parking brake shoe adjustment device of the Boxster has a finer toothing than the Boxster S!
- The parking brake shoes and the return springs are also different!

- Only for Boxster: Next, turn back the adjustment fixture through 9 notches again (release approx. 5 notches until the brake disc can be turned freely, then release another 4 notches).
- Only for Boxster S: Subsequently turn back the adjustment fixture through 5 notches again (release approx. 3 notches until the brake disc can be moved freely, then release another 2 notches).

5. Repeat the procedure on the other wheel.
6. Pull up the parking brake lever by 2 teeth and adjust the adjustment nut of the turnbuckle until both wheels can be turned manually with difficulty.
7. Release the parking brake lever and check whether both wheels can be turned freely.
