Replacing The Master Cylinder
Preparations
Clean around brake fluid reservoir cap, by pipe connections, and, if necessary, by hose connection between reservoir and master cylinder to prevent dirt
entering braking system.
CAUTION: Release non-return valve in air hydraulic brake power assist unit (brake servo) or pump brake pedal until it goes hard to avoid any vacuum
remaining when undoing the master cylinder. Otherwise, there is a risk that the O-ring acting as a seal will be sucked into the servo and disappear.
Put rags under master cylinder to prevent brake fluid spillage on paint work surfaces.
NOTE: Do not open the master cylinder under any circumstances. It takes special equipment and facilities to reassemble.
