The brake booster in a vehicle makes use of the vacuum of an engine to amplify the force that the drive exerts to stop the vehicle. This device is fixed between the master cylinder and the brake pedal. As soon as you hit the brake pedal, this device increases the force you applied, thus slowing down the car within a few seconds. If you want to troubleshoot your brake booster, we suggest that you follow the tips given below.
1. Brake Pedal Won’t Pull Down
You may have this issue when you press the pedal in the process of starting up your vehicle. The brake is supposed to pull down a little bit in response to your action. However, if this doesn’t happen, know that you have an issue to resolve, which is related to the vacuum of your vehicle.
The problem may arise due to the vacuum or fluid leakage because of the worn out hose, piston or valve. In this case, you will need to replace the faulty component to fix the issue.
2. Vacuum Failure
When the engine of your vehicle accelerates, the vehicle shouldn’t have the vacuum failure. But if this happens, you may need to check the check value and get it replaced if it’s the cause of the problem. It can be found inside the inlet fitting. Once replaced, if the issue is still there, you may want to replace the brake booster.
3. Locked-Up Brakes
You may want to use fresh brake fluid if your brakes don’t release properly. What happens is that hygroscopic brake liquid tends to absorb moisture. Moreover, an excessive amount of water in the fluid may lead to vapor lock. As a result, the wheels of your vehicle may have to bear more pressure.
4. Air Noise
You may hear the air noise from under the dash of your vehicle. According to experts, this is not an issue. The sound is generated when you apply the brakes and the air gets into the filter of the booster. You can reduce the noise easily. All you need to do is move around the silencer.
5. Brake Pedal Won’t Return
If the brake pedal won’t go back after you have released it, you can troubleshoot it. You may have a faulty brake booster spring. According to experts, if your vehicle has a broken spring, the brake light may stay on even if you have released the pedal. Aside from this, the broken spring may cause overheating issues as well.
