Replacement procedure
Before commencing replacement, ascertain that the spare parts used for replacement are suitable for the make and model of the vehicle.
- Remove the wheel.
- Make a note of the position of all the partially or fully disassembled components for correct reassembly.
1. Disconnect the wear indicator cable (point 1), where present, from the terminal in the vehicle, releasing it from any attachments on the chassis and on the caliper.
2. For models fitted with safety split pins (point 2), remove them using pliers.
3. In the case of dual-disc calipers, remove the springs (point 3) using pliers.
4. Pull out the pin(s) (point 4) using a hammer and pin driver. Pull out completely by hand, making sure you keep the springs (point 5) in position.
5. Remove the spring(s) (point 5). Check the fluid level. Open the brake fluid reservoir cap.
CAUTION! The piston pulling back steps described below cause the brake fluid level in the reservoir to rise. Make sure the level of brake fluid won’t cause a leak, as this would damage the painted parts of the vehicle.
FIXED CALIPERS type A B
1. Pull away the pistons slightly using a retractor or other suitable tool, pressing on the pads (point 6).
The piston pulling back must subsequently allow the caliper to be loosened from the disc.
The piston pulling back must subsequently allow the caliper to be loosened from the disc.
2. If the design of the caliper allows it, remove the pads. Otherwise remove them after disassembling the caliper. If you intend to re-use the pads, mark the rotation direction of the disc on them with a marker.
FLOATING CALIPERS type C
1. Take out the pads, while at the same time sliding the caliper body backwards and forwards on the guiding bushes (point 7). Sliding the caliper body pulls the pads slightly away from the disc, making them easier to remove.
If the dent created by the disc wear obstructs the extraction of the pads, disassemble the caliper body:
1. Disassemble the screws (point 8) using a spanner.
2. Using a screwdriver, prise the guiding bushes out from the dedicated seats.
3. Take out the guiding bushes (point 7) enough to detach them from the caliper bracket (point 9).
4. Separate the caliper body (point 10) completely from the caliper bracket (point 9) and hang it into the vehicle chassis using an S-shaped hook.
5. Take out the pads.
6. If you intend to re-use the pads, mark the rotation direction of the disc on them with a marker.
7. For the rear calipers (with parking mechanism), disconnect the parking control cable (point 11).
DANGER! The brake fluid lines must remain loose and not stretched. If you stretch the lines, they could break and brake fluid could leak out.
For all types of calipers
1. Close the brake fluid reservoir cap.
2. Place a spacer (point 12) inside the passenger compartment between the seat and the brake pedal to make sure the pedal remains pressed for the duration of these operations.
WARNING! This allows the brake hydraulic circuit to be closed, avoiding any brake fluid from leaking.
CAUTION! During all the phases described below, make sure the brake fluid does not come into contact with parts of the vehicle which would be damaged, especially painted parts. Promptly wipe off any accidental fluid splashes or leaks with kitchen towel and clean with water.
