WM 474119 Removing and installing rear brake caliper
Preliminary work
1. Raise the vehicle.
2. Remove wheel.
Removing rear brake caliper (standard brake system and PCCB)
1. Open combination plug connection and pull out connector for brake pad wear indicator. Unclip brake pad wear indicator wire from the holders.
2. Loosen holder (M6 screw) -2- and brake line -1- at the brake caliper. Close off brake line and brake caliper using suitable plugs.
Loosen fastening screws -3- and remove brake caliper (with brake pads fitted).
Brake caliper/brake line
Installing rear brake caliper (standard brake system and PCCB)
1. Fit brake caliper on wheel carrier. Use new fastening screws -3-. Tightening torque: 85 Nm (63 ftlb.).
Fit brake line -1- and holder (M6 screw) -2- on brake caliper.
Tightening torques: Brake line -1- = 12-14 Nm (9-10.5 ftlb.)/holder (M6 screw) -2- = 10 Nm (7.5 ftlb.).
Brake caliper/brake line
2. Route brake pad wear indicator wire (clip it into the holders) and connect the connector to the combination plug connection. Lock combination
plug connection.
3. Bleed the brake system and adjust the brake fluid level.
Bedding in the brake pads standard brake system
New brake pads require a bedding in period of approx. 200 km. Only then do they achieve their maximum braking effect. The slightly reduced braking
effect must be compensated for by increased pressure on the brake pedal. The same also applies after a brake disc change.
Bedding in the brake pads PCCB
New brake pads require a slightly longer bedding in period for PCCB brake discs than cast iron brake discs.
In general, the following applies: New brake pads must be worn in (bedding in period), their optimum braking effect is not reached until after a few
hundred kilometers. The slightly reduced braking effect must be compensated for by increased pressure on the brake pedal. The same also applies
after changing brake discs.
