Vacuum Brake Booster: Service and Repair
Vacuum Booster Assembly
Removal
1. Before removing the vacuum booster assembly, disconnect and remove the brake pipes.
2. Remove master cylinder.
Caution: When removing the master cylinder from the vacuum booster, be sure to get rid of the internal negative pressure of the vacuum booster
(by, for instance, disconnecting the vacuum hose) in advance.
If any negative pressure remains in the vacuum booster, the piston may possibly come out when the master cylinder is being removed, letting the
brake fluid run out.
While removing the master cylinder, further, do not hold the piston as it can be easily pulled out.
Outside surface of the piston is the surface on which seals are to slide. Care should be taken to keep the surface free of cuts and dents.
3. Remove vacuum hose.
4. Disconnect the yoke clevis from the brake pedal.
5. Remove vacuum booster fixing nut.
6. Remove vacuum booster.
Inspection and Repair
Vacuum Hose (The built in check valve)
1. Inspect the check valve (2), which is installed inside the vacuum hose.
2. Air should pass freely from the vacuum booster (3) to the engine (1).
