Front Without PCCB

Removing and installing front brake pads





Preliminary work

Remove wheel.

Removing front brake pads

Removing front brake pads - 6-piston calliper

The core of the warning contact wire must not be left exposed. Worn insulation is not important.

If necessary, remove a little brake fluid from the reservoir by suction in order to prevent an overflow when the disc brake pads are pushed back.

1. Remove fastening screw at the retaining pin. Then screw auxiliary screw (M8) into the retaining pin. Hold down the expanding spring with a screwdriver and remove retaining pin.





2. Remove warning contact wire at the brake calliper and expanding spring. Remove warning contacts from the disc brake pads.
3. Brake piston resetting fixture 9472 (for 6-piston calliper) must be positioned on the brake calliper between the disc brake pads. Then press the pads back evenly -Direction arrows-.





4. Remove disc brake pads.

Installing front brake pads - 6-piston calliper

Warning
Risk of accidents if brake pads with the wrong brake pad quality are installed.
This can result in longer braking distances and more wear.

- Use only the type-specific brake pads.

Warning
Increased risk of accidents if old parts are fitted on brake calliper.
This can cause malfunctions.

- Fit new expanding spring, new retaining pin and new retaining pin screw on the brake caliper.

Make sure the retaining pin is inserted at the correct position. The side levelling surfaces prevent the retaining pin from twisting in the brake calliper.
Do not grease the back of the disc brake pad.
Check disc brakes for wear.
The core of the warning contact wire must not be left exposed. Worn insulation is not important.
Use a new repair kit.
Remove a little brake fluid from the reservoir using suction if necessary.

1. Before fitting the brake pads, check the brake discs for wear.
2. If necessary, push the brake pistons back into their original position using the brake piston resetting fixture 9472 (for 6-piston brake calliper).

3. Insert new damping plates into the pistons.

Always remove the protective film on the damping plates before installation.





Damping plates in brake pistons

When fitting the damping-plates on the small pistons, position the cut-out on the damping plate -Arrow- at the brake-pad guide pin because otherwise the damping plate will be deformed.

4. Install new disc brake pads.
5. Fit expanding spring. Center the retaining pin in the bore using the M8 auxiliary screw. To do this, push the retaining pin back with the auxiliary screw and then push the retaining pin through. Remove auxiliary screw and tighten new fastening screw at the retaining pin to 30 Nm (22 ftlb.).





6. Fit warning contact wire on the disc brake pads, expanding spring and brake calliper -Arrows-.





7. Position disc brake pads by actuating the brake several times.
8. Check brake fluid level and correct if necessary. The brake fluid level must be between the MAX-MIN marking.

Bedding in the brake pads

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.
