What is a brake vacuum pump replacement?

If the vacuum pump is faulty or damaged, the mechanic will disconnect the brake booster and remove the vacuum pump before installing the new one. 
The vacuum pump is a key part of the brake booster, a device that enhances the braking system in turbo or diesel vehicles. When you push your brakes, a small amount of air is let into the chamber of the brake booster through a valve, which also seals off the vacuum. The air pressure strengthens the force of the brake.
Turbo and diesel engines need a vacuum pump to extract the air and create the vacuum necessary for the brake booster to function. The vacuum pump reduces reliance on the engine for the vacuum. 

How to replace your brake vacuum pump

Since the vacuum pump is part of the intricate brake booster device, the process to replace it can be pretty involved. Here’s an overview of how it’s done:
  • The mechanic will disconnect the battery and locate the faulty vacuum pump before raising up the car and removing the engine shield. 
  • The mechanic will then disconnect the brake booster vacuum pump hoses and electrical connector, then remove the brake booster vacuum pump from the mounting bracket. 
  • The new vacuum pump is then installed onto the mounting bracket, followed by the hoses and electrical connector. 
  • The battery is reconnected. 
  • The mechanic will test the brakes to check the brake booster vacuum pump performance. 

When do I need to get my brake vacuum pump replaced? 

Each car needs brake vacuum pumps replaced at different times, so check your vehicle’s manual to find out how often you should be getting it checked. That being said, there are a few indicators that you might need to replace your vacuum pump:
  • Your brakes are poky or slow to respond
  • You have to push your brake pedal extra hard to make your car stop
  • You hear a hissing noise when you push your brake pedal 
  • Your brake pedal slips to the floor when your car is running and stationary 
  • You have difficulty braking in heavy traffic situations when you have to stop quickly multiple times
Because a faulty brake vacuum pump diminishes the strength and efficiency of your brakes, it can be a safety hazard if you don’t get it repaired promptly.
