Withdrawal
Remove decorative cap. Mark the position of the rims on the wheel hubs with paint. Thanks to this, the subsequently balanced wheel is set to the same position.
Loosen wheel bolts.
Raise the front of the car and remove the wheel.
Loosen brake caliper mounting bolts -1- and remove brake caliper from brake disc.
Hang the brake caliper on a wire so that the brake hose and wear indicator wire are not stretched or kinked.
Caution: Do not unscrew the brake hose, otherwise you will have to bleed air from the brake system.
If complete removal of the brake caliper is required, the brake hose must first be unscrewed. In other cases, the brake hose may not turn off.
Caution: Collect leaking brake fluid in a bottle intended exclusively for brake fluid. You can also suck the brake fluid out of the expansion tank.
Unscrew bolt -4- with a 5 mm open end wrench.
Remove brake disc.
Installation
To ensure uniform braking on both sides, the surfaces of both discs must be the same in surface finish and finish. Therefore, perform simultaneous replacement or processing of both disks.
A service station can check the runout of the discs. Maximum lateral runout (in position): 0.2 mm.
Measure the thickness of the disk.
If present, remove rust from brake disc flange and front wheel hub.
Remove the varnish from the surface of the new disc with a nitro thinner.
Slide the brake disc onto the wheel hub and secure with the bolt. Pre-turn the brake disc so that the bolt holes match.
Fit the brake caliper with the brake pads inserted. Do not tighten or kink the brake hose while doing this. Check the freedom of movement of the brake hose when turning the steering wheel from lock to lock.
Fasten the brake caliper with a tightening torque of the bolts of 120 Nm.
Attention: If the brake hose is loosened, the brake system must be bled.
Place the wheel in compliance with the marked position of the disk on the hub. Lower vehicle and cross-tighten wheel bolts to 110 Nm.
Caution: With the vehicle stationary, depress the brake pedal several times until you feel resistance.
Check the brake fluid level in the expansion tank, top up if necessary up to the MAX mark.
