What is the Vacuum Brake Booster Check Valve all about?

The vacuum brake booster check valve is part of the brake booster, and plays an essential role in brake system operation. It is a one-way valve that allows air to be sucked out of the booster, but does not allow air to enter it. This is a safety solution to ensure that if the engine is turned off, or if frequent stops or pedal presses are required, the brakes still operate. Its capacity ensures that you have enough boost for several brake applications. The vacuum brake booster check valve connects the vacuum hose from the engine to the body of the brake booster.

Keep in mind:

  • The vacuum brake booster check valve is not designed to require maintenance, so it will not be inspected during routine services.
  • Damage to the vacuum hose from the engine can mimic problems with the check valve.

How it's done:

  • The faulty vacuum brake booster check valve is located and identified
  • The vacuum brake booster check valve is removed
  • The new vacuum brake booster check valve is installed
  • The brakes are tested for proper vacuum brake booster check valve operation
  • The vehicle is road tested and checked for proper vacuum brake booster check valve and brakes operation

Our recommendation:

Many different issues can create problems with the braking system, including air in the lines, dirty/burned brake fluid, and more. If you suspect a vacuum brake booster check valve issue, have one of our expert mechanics diagnose it.

What common symptoms indicate you may need to replace the Vacuum Brake Booster Check Valve?

  • Brake pedal feels spongy when pressed
  • Brake pedal is very hard to press
  • Brake pedal begins as easy to press then becomes very difficult

How important is this service?

While a leak in the vacuum brake booster check valve will not eliminate your ability to stop, it will make braking much more difficult and increase your stopping distance. It should be repaired as soon as possible.

Lexus GS400 V8-4.0L - Alternator - Jenks, Oklahoma
After having my car sit in my garage for a month with a dead alternator, I found yourmechanic.com, and more specifically, Nathan Thorne. YourMechanic.com's website was super easy to use, they already had the repair I needed in their system, gave me an exact quote, and let me pick when the repair was going to happen. Now the best part. When the mechanic came out, he determined that the repair was going to take significantly longer than they had quoted...AND DIDN'T UPCHARGE ME. He just did the repair and said since the company's quote on the time for the repair was wrong, he would just deal with them. Couldn't have asked for better service and will definitely recommend and use Nathan Thorne again.

Lexus GS400 V8-4.0L - Inspection / Diagnostics - Los Angeles, California
While AAA essentially diagnosed and fixed the (immediate) problem with my vehicle, Chris followed up with a more thorough inspection of my engine, brake pads, and tires. There is only so much you can check on without the car being pulled to a station or a shop, however Chris did ALL that he could while he was there servicing my vehicle. Aces across the board!
