How to Check a Vacuum Booster?
1 Answers
When checking the one-way valve of the vacuum booster, compressed air should pass when blown in the direction of the arrow on the valve body, but not in the reverse direction; the one-way functionality can also be tested by sucking with the mouth. Below is relevant information about the vacuum booster: 1. Introduction: It is generally located between the brake pedal and the master cylinder. For ease of installation, it is usually integrated with the master cylinder as a single unit, with part of the master cylinder extending into the vacuum booster housing; 2. Basic Structure: It mainly consists of a vacuum servo chamber and a control valve. If the vacuum booster fails or there is no vacuum in the vacuum line, the control valve push rod will directly push the diaphragm seat and the master cylinder push rod to move via the air valve, generating braking pressure in the master cylinder, but the force required on the pedal will increase.
