Withdrawal
Paint mark the position of the wheel in relation to the hub. This is necessary to reinstall the wheel in its original position, as a result of which its balance is maintained.
With the vehicle on wheels, loosen the wheel bolts.
Raise the corresponding part of the car and fix it on stands, unscrew the bolts and remove the wheel.
Unscrew the two bolts shown by the arrows in Figure 11.15 and remove the caliper assembly from the brake disc. The picture shows the front caliper. To remove the rear caliper, unscrew the two socket head cap screws.
Remove the brake hose from the bracket.
Raise the caliper and with a soft wire, tie it to the front rack, while the caliper should not hang on the brake hose, and also be stretched or twisted.
Attention. Do not unscrew the brake hose, otherwise you will have to bleed the hydraulic brake system after assembly.
If the caliper needs to be removed, follow these steps.
On the front wheel caliper, clean the area near the connection of the brake hose and brake pipe, and unscrew the brake pipe from the brake hose coupling. Close the openings in the brake hose and pipeline with suitable plugs.
On the rear wheel caliper, clean the area near the junction of the brake hose and the brake pipe and unscrew the brake pipe at the brake hose connection and, if necessary, unscrew the brake hose from the caliper. Close the openings in the brake hose and pipeline with suitable plugs.
Attention. When the hydraulic brake brake is opened, brake fluid flows out. To reduce the loss of brake fluid, remove the cap from the reservoir of the brake system, close the neck of the reservoir with polyethylene and screw the cap back on. This is necessary so that the lid hermetically closes the replenishment tank.
Remove the brake disc.
Installation
Attention. If the brake disc needs to be replaced, the second brake disc must also be replaced to ensure uniform braking. When replacing the brake discs, the brake pads must also be replaced.
Check and, if necessary, clean the mating surfaces of the brake disc and hub. When installing a new brake disc, remove the protective coating from its surface.
Install the brake disc on the wheel hub.
Install the caliper with brake pads. Do not kink the brake hose while doing this. Check that when the front wheel is fully rotated, the brake hose does not come into contact with the front suspension elements and the body.
Attach the brake hose to the bracket.
Fasten the caliper with bolts and tighten the bolts of the FN-3 front caliper to 120 Nm and the HP-2 caliper to 190 Nm. If bolts with a ribbed head base are being reinstalled, use a wire brush to clean the ribbed surface.
Secure the rear caliper with bolts, tightening them to a torque of 95 Nm. If bolts with a ribbed head base are being reinstalled, use a wire brush to clean the ribbed surface.
If the brake hose was disconnected, screw it back in place.
Remove the polyethylene from the filler neck of the replenishment tank and bleed the appropriate brake circuit.
Connect the parking brake cable to the rear brake caliper.
Apply a thin layer of lubricant to the shoulder that centered the wheel disc. Install the wheel, aligning the previously applied marks, and secure it with bolts. Lower the vehicle to the ground and tighten the wheel bolts to 120 Nm.
Attention. Depress the brake pedal several times until the brake pads press against the brake disc.
Check the brake fluid level in the reservoir and top up if necessary.
