FRONT BRAKE

Important

Bold reference numbers in this section identify parts not shown in the figures alongside the text, but which can be found in the exploded view diagram.

Removal of the front brake master cylinder

Warning

The brake master cylinder manufacturer advises against servicing the brake master cylinder due to the safety critical nature of this component. Incorrect overhaul of this component could endanger rider safety.

Maintenance operations on these units are limited to renewal of the following parts: control lever, fluid reservoir assembly and relative fasteners and master cylinder fasteners.

If the hose connecting the master cylinder to the brake caliper is changed, ensure that the hose end fittings are positioned correctly.

Warning

If incorrectly positioned, the hose can affect brake operation and foul moving parts. Position the hose as shown in the figure.
