Service Overview

While vacuum pumps are essential to the workings of diesel and hybrid engines, they can also boost performance in petrol engines. Installing the right vacuum pump with a product from our range can significantly improve your cars response and efficiency. Vacuum pumps draw out the gas molecules from a sealed chamber to create a vacuum.

In diesel and hybrid engines, the vacuum pump is solely responsible for supplying a vital vacuum to the brake servo. They can also be used to power the motors that control the air flow in car ventilation systems, the throttle driver in cruise control systems and even the central locking system. Whether responsible for your brakes or your security, a reliable vacuum pump is essential and should be immediately replaced if malfunctioning.

Frequently Asked Questions

The Vacuum Pump is a device that helps enhance the effects of the hydraulic braking system in cars as a supplement to the primary braking mechanism. In cars with turbo charging or diesel fuel, the engine does not create the necessary vacuum, so they need an additional brake booster vacuum pump to draw out the air and create the vacuum needed for the brake booster to function.
  • Brake pedal hard to press
  • Leaking oil under the side of the engine
  • Delayed brake response
  • Excessive pressure needed to make the brake respond
  • Hissing sound when you press the brake pedal
  • Brake pedal slips to the floor when engine is running
  • Air conditioning not working
Yes, vacuum leaks in today's computer-controlled engines can cause very serious engine damage. Because the vacuum leak pulls in outside air, immediately the fuel air ratio is altered to a lean condition. The lean air fuel condition is picked up by the exhaust oxygen sensors who, in turn, report this to the computer.
This pressure is used to power multiple belts and pulleys ranging from alternators to AC units but is released thanks to the use of a vacuum pump. A diesel engine on the other hand relies on vacuum pumps to provide power for other systems, most notably the brake system and in many cases, the air conditioning system.
When a vacuum leak exists, it's most commonly caused by vacuum hoses that are broken, have faulty connections or the vacuum pump is not in operation. This can lead to poor fuel efficiency and other engine performance issues.
