Withdrawal
Remove the rear wheel brake caliper.
Loosen the mounting bolt (arrow) rod wrench 5 mm.
Fully release the parking brake.
Remove brake disc. If the brake disc cannot be removed, separate the brake pads (see section «Parking brake»).
Installation
To ensure uniform braking on both sides, the surfaces of both discs must be the same in surface finish and finish. Therefore, it is necessary to replace both disks at the same time.
A service station can check the runout of the discs. Maximum lateral runout (in position): 0.2 mm.
Measure disc thickness (see section «Checking the thickness of the brake discs»).
Installation
Clean new discs with nitro thinner to remove protective varnish.
Slide the brake disc onto the wheel hub and secure with the bolt. Pre-turn the brake disc so that the bolt holes match.
Install brake caliper with 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. Screw the brake caliper (see section «Removal and installation of a brake support of a brake of a back wheel»).
Fasten the brake caliper with a tightening torque of the bolts of 120 Nm. Coat the bolt threads with engine oil first.
Attention: If the brake hose is loosened, it is necessary to bleed the air from the brake system (see section «Removal of air from the brake system»).
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.
Attention: With the vehicle at a standstill, press the brake pedal several times until a noticeable resistance appears.
Check the brake fluid level in the expansion tank, top up if necessary up to the MAX mark (see section «Check of level of a brake liquid and a control lamp of lowering of level of a brake liquid»).
Run in new brake discs in three steps.
- Phase 1: 5 hard stops at 50 km/h on a road with little traffic.
- Phase 2: Let the brakes cool down.
- Phase 3: 5 more hard stops at 50 km/h.
