The brake discs must be replaced in pairs, i.e. on both wheels of the same axle. The brake pads should also be replaced (see Section Replacement of brake pads).
1. Remove wheels. Remove and clean brake pads if necessary (see Section Replacement of brake pads).
2. Turn out bolts of fastening of a support and suspend it on a body, without disconnecting a brake hose.
bolts (1) rear brake caliper mounting
Bolts of fastening of a support of the forward brake mechanism
The brake hose must not be stressed.
3. Turn out a bolt and remove a brake disk.
To loosen the brake disc fastening bolts, it is not allowed to hit the friction ring with a hammer or something similar! If necessary, gently tap the base of the brake disc with a soft-faced hammer.
4. Thoroughly clean the mating plane with the brake disc on the wheel hub, if necessary, remove traces of corrosion. Irregularities on the mating plane can lead to warping of the brake disc.
5. Ventilated brake discs are balanced by balancing brackets mounted on the inside diameter of the disc - do not remove or move them.
6. Measure the brake disc thickness and replace if necessary.
7. Installation is carried out in the reverse order. After completing work on the rear brake, adjust the parking brake (see Section Parking brake adjustment).
