Attention! Brake calipers must be replaced in pairs for each axle!
Front wheel brake
Details of installation of a support of the brake mechanism of a forward wheel
1. Details of the installation of the front wheel brake caliper are shown in the illustration, to which all references in the text refer.
2. Remove the front wheels.
3. If equipped, disconnect the electrical wiring (1) and remove the brake pad wear contact sensor (S10/1 - in case of left brake mechanism), the self-locking fixing bolts must be replaced without fail.
4. With the help of a special gate, depress the foot brake pedal so that the replenishment port of the GTZ is blocked. To relieve pressure, release the bleed valve of the corresponding support - try not to allow the fluid level in the reservoir to drop too much.
5. Remove the hollow bolt (51b) nipple connector for connecting to the flexible brake hose caliper (51).
6. If necessary, remove the brake pads (see Section Wear assessment and replacement of brake pads).
7. Remove the self-locking mounting bolts (35) and remove the caliper (31a) from the steering knuckle - the bolts must be replaced without fail.
8. Installation is in reverse order - do not forget to replace the sealing washers (51a) plug connector.
9. Finally, bleed the brake system (see Section Bleeding the brake system).
