What is Vacuum Pump?
The brake booster vacuum pump provides the vacuum needed for the power brake booster to perform. If it fails or has a problem, the car will be left without  assisted braking. Without the brake booster, the brake pedal will be stiff and will require more effort to stop the car. Vacuum  boosters  will probably be with us for a long time. It is the most efficient and economical way to amplify the force exerted by the driver. But where the booster gets its vacuum. Many auto parts providers have been using vacuum pumps to power the brake booster on their vehicles. For a vacuum brake booster to work, it needs a source of vacuum. In the past all that was needed was a port on the intake manifold. Now, vacuum pumps are the choice for negative pressure power.
