Brake Master Cylinder: Service and Repair

RESERVOIR SEALS - Renew
With the booster unit removed, and brake fluid drained, is possible to fit new reservoir seals. Clean the unit thoroughly before removing the reservoir.





1. Remove the reservoir bracket securing bolt adjacent to the low pressure suction hose outlet.
2. Carefully ease the reservoir away from the booster unit.
3. Remove the two seals located in the top of the booster unit. Avoid damage to the seals which could result in rubber particles entering the system.
4. Fit new seals and refit the reservoir, tightening the securing bolt to 9-11 Nm (7-8 ft lb).
