Vacuum pumps are essential components in the braking system and in engine support systems. They generate vacuum that supports the brake servo, ensuring efficient braking with minimal driver effort. In modern vehicles, vacuum pumps can also supply other systems, such as the EGR system, valve systems or turbocharger control. In the Global Parts automotive store you will find a wide selection of used car parts including vacuum pumps, perfectly matched to BMW , Audi , Mercedes , Volkswagen , Mini and other brands .
What functions do vacuum pumps perform?
Vacuum pumps play a key role in the functioning of the braking and engine power steering systems:
- Vacuum Generation – Provides the vacuum needed to power assist the brakes, facilitating effective braking.
- Support for control systems – They provide vacuum to EGR valves, turbochargers or flaps in the intake system.
- Increased safety – Thanks to an efficient vacuum pump, the braking system operates with full efficiency in every situation.
Why is it worth taking care of vacuum pumps ?
Vacuum pump failure can lead to serious brake and engine problems, affecting vehicle safety and performance. Typical symptoms of failure include:
