WM 463502 PCCB - Checking rear brake pad
Information
Information on checking brake pads
Procedure during intermediate maintenance:
Visually inspect the brake pads for wear. There is no need to remove the wheels unless the brake fluid needs to be changed at the same time.
Outside of brake pad: Visual inspection through the cut-outs in the rim.
Inside of brake pad: Visual inspection from below with vehicle raised.
Without an aid, the inner brake pad is not or is only partly visible on the rear axle (with the wheel fitted).
On vehicles with a stone guard on the lower wishbone, this must be removed to get a better view of the brake pads.
A mirror can be used as an aid -arrow-.
Example: Examining rear brake pads
Procedure during maintenance:
Raise the vehicle -> 40 Lifting the vehicle - section on "Preliminary work".
NOTICE
Removing/fitting wheels
- Risk of damage to (ceramic) brake discs
-> Use two assembly pins when removing and fitting the wheel.
-> Carefully guide the wheel towards the wheel hub, thereby preventing any heavy impact on the (ceramic) brake disc.
Screw the two assembly aids (assembly pins) -1- , instead of two wheel bolts, into the wheel hub before removing/fitting the wheel. During removal, first remove the 3 remaining wheel bolts and remove the wheel carefully, without touching the brake discs.
Remove wheel. Use assembly aids (assembly pins) -1-.-> 44051900 Removing and installing wheel.

Check the brake pad thickness for wear. If in doubt following a visual inspection, you may have to measure the thickness.

WARNING
Installation of brake pads with the wrong brake pad quality
- Longer braking distance
- More wear on brake pads
-> Only use the type-specific brake pads listed in the Porsche Parts Catalogue.
-> Replace the brake pads when the brake pad wear indicator light comes on, but no later than when there is a residual pad thickness of 2 mm on each axle.
-> Replace the brake discs on each axle upon reaching the wear limits.
Information
- If brake pad wear is indicated by the warning light, the warning contact (sender including wire and plug connection) must also be replaced.
- Replacement of the warning contact can be avoided by replacing the brake pads no later than when the pad thickness is 2.5 mm -arrows-.
Checking brake pad thickness
- Warning contacts must be replaced if the core of the line is worn.
- However, if only the plastic part of the warning contact is worn, there is no need to replace it.
