Removing
Loosen wheel bolts.
Jack up and support the front end.
Remove front wheel.
5. Cover. 16. Brake hose. 20. Self-locking bolts. 23. Steering trapezoid lever. 26. Plug connector. 27. Wire support.
Loosen fixing screws (3) and remove the caliper (2) with stub axle (6).
Hang the caliper on a wire hook (shown by arrow) so as not to kink or kink the brake hose and brake pad wear indicator wire.
Attention: Do not disconnect the brake hose, otherwise you will have to bleed the brake system.
Remove the hub.
Remove three hexagon bolts M12x1.5 into the front of the hub (on the side on which the wheel is mounted).
Set the front of the hub (10) into a vise so that the jaws of the vise rest on the bolts. Loosen fixing screws (9) from the hub (10) using a socket wrench and remove the brake disc (1).
Installation
In order for both wheels to brake equally, it is necessary that both discs have the same degree of surface finish. Therefore, discs should always be replaced in pairs (on both wheels).
Remove rust from the disc flange and from the front of the hub.
Wipe new discs with solvent to remove the protective coating from them.
Attach the new disc to the hub using new self-locking hex bolts.
Install the wheel hub onto the stub axle, reinstall the outer wheel bearing and tighten the nut.
Adjust the axial clearance of the wheel bearings.
Fasten the caliper to the stub axle with new self-locking bolts.
Caution: Be careful not to kink or kink the brake hose.
Replace the wheel, lower the machine and tighten the wheel bolts in a diagonal sequence.
Attention: After finishing work, press the brake pedal several times to allow the new disc to rub against the brake pads.
Check the fluid level in the brake reservoir.
