Adjusting the parking brake shoes

Includes: adjusting parking brake shoes and parking brake cables

Check the free play of the handbrake lever
The handbrake has asbestos-free brake linings. 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 being apparent.

Adjusting the parking brake
1. Remove the rear wheels.
2. Undo the handbrake lever and push back the disc brake pads of the rear axle until the brake disc can rotate freely.
3. Undo the adjustment nuts on the turnbuckle (arrow) until the cables are without pretension.





Note To make the turnbuckle accessible, open the cover of the tray behind the handbrake lever and remove the rubber inlay and also the insert.

4. Adjust the right and left parking brake shoes.
Boxster: see 4a in following text.
Boxster S: see 4b in following text.

Note The 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.
