Brake System Condition Probable cause Corrective action Weak brakes Fluid leakage from wheel cylinders. Fluid leakage from caliper cylinders. — Master-Vac — This problem mainly results from improper function of Master-Vac. Please check as follows: Improper master vac function due to poor vacuum. Required vacuum is not maintained. Wipe and clean the brake shoe linings, service the wheel cylinder replacing damaged parts, and bleed the system. Take down and strip the calipers; replace all rubber seals and clean lining pads. Check the pipe or hose connections, and fasten if necessary. Or replace a faulty vacuum hose. Wipe, clean or replace the check valve and check the grommet for loose fit, re-fit or replace it. Replace seal or retighten plate and seal assembly-to-front shell bolts. Clean or replace poppet rubber. Replace diaphragm and diaphragm plate. Weak pressure on shoes due to use of too thick fluid. Flush the system and refill with specified fluid. Bleed the system. Dust on drums or linings soiled with oil. Weak shoe return springs. Drum out of round. Remove and clean drums thoroughly. Check springs and replace as required. Correct drums by means of a lathe.
