Information on PCCB brake pads
Damping plates in brake pistons
Since the production launch, Pagid-P40-2 brake pads with -brake-piston damping plates- have been fitted on the front axle for PCCB brakes.
Brake-piston damping plates no longer used
With the introduction of modified brake pads - Pagid P40-3 - the brake piston damping plates are no longer used.
Preliminary work
Remove wheel.
Removing front brake pads - PCCB brakes
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 the M8 auxiliary screw 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 brake 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.

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.
- 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.
Warning
Old mounting parts fitted on the brake calliper
^ Reduced braking effect
^ Risk of damage to the brake calliper
- Fit new expanding spring, new retaining pin and securing clip on the brake calliper.
^ 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.
1. Before installing the brake pads, check the amount of wear on the brake discs.
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. Fit new disc brake pads.
3.1. If you are using Pagid P40-2 brake pads, insert new damping plates into the pistons.
Damping plates in brake pistons
The protective film on the damping plates must be removed before installation. When fitting the damping plates on the small pistons, position the cut-out on the damping plate at the brake pad guide pins to prevent the damping plate from becoming deformed.

3.2. Do not fit brake-piston damping plates if you are using the modified brake pads (Pagid P40-3)!
4. Install 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.).
5. Fit warning contact wire on the disc brake pads, expanding spring and brake calliper -arrows-.
6. Position disc brake pads by operating the brake several times.
7. Check the brake fluid level and correct it if necessary. The brake fluid level must be between the MIN/MAX marking.

Bedding in the brake pads
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.
Subsequent work
Fit wheel.
