Q:
How to check, remove, and install a vacuum or hydraulic booster? Posted by Customer
A:
To check the operating and airtightness of a vacuum booster, depress the pedal and start the engine, ensuring that the pedal goes down slightly and that there is no change in the pedal reserve distance. For a hydraulic booster, turn off the engine and depress the brake pedal several times to deplete the pressure in the accumulator, then push down on the brake pedal with approximately 40 pounds of force and start the engine. If the booster is working properly, the brake pedal will sink toward the floor and then rise back up against your foot. To remove the booster, disconnect the cable from the negative battery terminal, detach the vacuum or pressure and return lines, remove the master cylinder, disconnect any electrical connectors, remove the pushrod retaining clip and the four nuts holding the booster to the firewall, and slide the booster straight out from the firewall. To install the booster, use a new gasket and tighten the mounting nuts to the torque specifications, and if working with a hydraulic booster, bleed the power steering system and check the fluid level.
