Bold reference numbers in this section identify parts shown in this exploded view diagram. These parts do not appear in the figures near the text.

Removing the front brake master cylinder

Critical safety components. The brake master cylinder manufacturer recommends that you do not attempt to service the internal components of the brake master cylinder. Incorrect overhaul of these critical safety components can endanger rider safety.

Maintenance operations on these units are limited to replacing: control lever, reservoir unit and reservoir and cylinder fasteners.

When fitting a new hose between the master cylinder and the caliper, care must be taken to position the connectors on the cylinder and the transmission unit at the correct angles.

Incorrectly positioned hoses can cause brake faults and interfere with moving parts. See proper position shown in figure.
