Adjusting The Parking-Brake Shoes
WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2013 Porsche 911, 2012 Porsche 911, 2011 Porsche 911, 2010 Porsche 911, and 2009 Porsche 911. However, it is still accessible from the selected car via links, so may be relevant.
This includes: Checking the free play of the parking-brake lever and adjusting the parking-brake shoes. The parking-brake cable cannot be adjusted (automatic cable adjustment).
- Remove the rear wheels.
- Undo the parking-brake lever and push back the disc brake pads of the rear axle until the brake disc can rotate freely.
- The adjustment fixture can be twisted through the bores in the wheel mounting.
- Turn the brake disc in such a way that the adjustment fixture becomes visible. Using a -screwdriver- inserted through the bore, move the adjustment device until the wheel can no longer be turned. To be specific, this means: put transmission in neutral. Further torque of the brake disc between 50 Nm and 150 Nm (37 ftlb. and 111 ftlb.) (test with torque click wrench on the drive shaft lock nut clockwise). Next, turn the adjustment fixture back again through 4 notches (release approx. 3 notches until the wheel can be turned freely, then release another 1 notch). Repeat the procedure on the other wheel. → Adjusting the parking brake
- Pull up the parking-brake lever (check free play). If 2 to 4 teeth or 4 to 8 teeth are engaged, it must be possible to turn both wheels by hand with considerable difficulty. 4 to 8 teeth applies to parking-brake levers with a modified/refined tooth system (introduction in standard production in February 2006).
- Release the parking-brake lever and check whether both wheels can be turned freely.
