Brake Booster

A step-by-step process starts the maintenance of vacuum brake boosters where components need removal according to their sequence. Begin by removing the vapor management valve (VMV) assembly together with its bracket for setting aside. Users must first disconnect the wiper arm nuts then remove the wiper arms before disconnecting the washer hose. The cowl cover must be removed after extracting the pushpins and the rubber trim. Move on to the vacuum brake booster service and repair by first removing the cowl brace center bolts and afterward removing the end bolts and the bracket. Remove first the coolant reservoir return hose before taking out the coolant reservoir bolts. The brake booster-to-brake pedal bracket nuts need replacement before you disconnect the brake pedal pin from the booster input shaft by removing its clip and separating the input shaft from the pin. The install process should be performed in reverse order compared to the removal stage.

Discard the four brake booster-to-brake pedal bracket nuts and tighten the new ones to 27 Nm (20 ft. lbs.) during installation.

After the cowl cover is removed, take out the cowl brace center bolts, the end bolts, and the bracket.

Disconnect the degas bottle return hose, then remove the two degas bottle bolts and position the degas bottle aside, tightening to 15 Nm (11 ft. lbs.) upon reinstallation.

First, remove the brake pedal pin clip and then detach the booster input shaft from the brake pedal pin.

Take out the pushpins and the rubber trim.
