DIY adjusting the foot brake?

[BobbySpeed]

Can anybody tell me how to adjust the foot brake on a Cayenne?

This basically the same process that is used on the sports cars.

Check free play on the pedal module:

- To do this, measure from the left seat rail up to the lower edge of the pedal plate on the FPB (Foot-operated parking brake)

1. Press pedal 40 mm (+ 5 mm). If this dimension is reached, the wheels must be able to turn without grinding the brake pads.

2. Press pedal 75 mm (+ 5 mm). If this dimension is reached, the wheels must be fixed. If the wheels can still turn, the FPB must be adjusted.

The rear wheels must be removed so that the adjustment device can be accessed.

1. Release the FPB pedal so that the wheels and brake discs can turn freely.

- The wheels may still grind slightly even then! If this happens, loosen the rear brake cables by moving them to and fro gently.

2. Remove rear wheels.

3. Adjust brake shoes (on both wheels). To do this, unscrew the plugs (arrow) and turn the brake disc with the opening towards the adjustment device position. Using a screwdriver, modify the adjustment device until the wheel can no longer be turned. Then unscrew 6 teeth (wheels must be free to turn).

4. Check the free play on the pedal module once again.

5. Mount rear wheels.

Loren- thank you for replying.

I did exactly what you stated because those were the directuins in the service manual; but, it also turned the axle with each turn, and didn't make a difference.

FYI: I just did the brakes on all for corners and thought that the traveling distance would have gotten shorter- but it was fine to begin with and now only works after depressing the pedal all the way to the floor. I replaced all the rotors, pads, spring kits and bled the brakes and my brakes are working perfectly.

You are turning a star wheel that turns a screw to move the brake shoes closer or moves them further away from the inside of the rear rotor (drum).

You might have to turn quite a bit to get them to cinch down so you can feel them.
