Note: New seals must be used between the reservoir and the hydraulic unit on reassembly.

Caution: Refer to the
precautions in Section 1.

Removal
1 Disconnect the battery negative lead.

2 Depressurise the hydraulic system by pumping the brake pedal at least 20 times, or until it becomes hard.

3 Disconnect the wiring multi-plugs from the reservoir cap and remove the cap.

Allow the fluid to drain out of the hose into the container. If fluid is accidentally spilt on the paintwork, wash off immediately with cold water.
