WM 463502 Checking rear brake pad (PCCB)
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 three 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.
