Installation Procedure
Note: Ensure that the residues of adhesive on the brake pad surfaces are removed and the surfaces cleaned afterwards.
1. Clean the guides for the brake pads in the top and bottom of the brake carrier (2) and contact surfaces with the brake pads on the brake piston (1) and the opposing surfaces (arrows). Clean the threads in the brake caliper.
Note: Replace brake caliper and/or brake carrier if the brake caliper is leaking, protective cap on piston is damaged or sealing sleeve on the brake carrier is damaged. Refer to Rear Brake Caliper Replacement (Rear Brake Caliper Replacement).
2. Inspect the brake discs for wear. Refer to Brake Rotor Surface and Wear Inspection (Brake Rotor Surface and Wear Inspection).
Warning: Refer to Brake Dust Warning (Brake Dust Warning).
Warning: Refer to Brake Fluid Irritant Warning (Brake Fluid Irritant Warning).
Note: The protective film (1) on the back of the brake pads must be removed after inserting the brake pads. Brake pad with mechanical wear indicator (if present) must be on the inside.
3. Insert the new metal guide sheets in the brake carrier.
* Apply the special grease to the brake carrier below the metal guide sheets (marked surfaces - enlargement (1).
* Insert the metal guide sheets (2) in the brake carrier.
4. Insert the new brake pads in the guide plates on the brake carrier.
Caution: Refer to Fastener Caution (Fastener Caution).
Note: Make sure that the sheet metal guides are not bent and the adhesive surfaces of the brake linings only contact the brake caliper after they have been correctly positioned.
