The braking system on your car requires a lot of pressure. The vacuum booster is one of the main sources of this pressure. This booster will take the pressure that is put on the brake pedal and minimize it so it is easier for you to push down in a hurry. The pressure that builds up in the booster will have to be bleed out once the car stops in order to reduce any issues. It is the job of the vacuum brake booster check valve to release this pressure when needed. Without this check valve, the braking components, such as the master cylinder, may become damaged due to the amount of pressure that is built up.
The check valve on your brake booster should last as long as the vehicle does. Due to the location of this part, it is rare that it will get any maintenance. Generally, the only interaction that you will have with this part is when it is broken. In some instances, the issues that you have with your check valve can mimic a problem with the vacuum system of the vehicle. The only surefire way to find out what is causing the problem is by having a professional to troubleshoot the vehicle for you.
The professionals will be able to find and fix the issues that you are having with this check valve without you having to lift a finger. Letting the professionals perform this type of work will reduce a lot of the stress that comes with this type of repair. Failing to get this issue handled quickly can make it very hard for you to use your vehicle’s braking system. Not having full use of your braking system is a recipe for disaster that can be avoided by taking action when repair issues surface. Have a professional mechanic replace the faulty brake booster check valve so no future problems arise while driving.
When your vacuum booster check valve is damaged, you may notice a few of these signs:
- The brake pedal feels very spongy when trying to press it
- It is very hard to press the brakes on the car
- The brake pedal goes all the way to the floor when barely pushing it
Taking notice of the signs that your vacuum booster check valve is damaged will allow you to get repairs done quickly.
