How to Check If Your Brake Booster is Broken
A power brake booster is an important part of your car's braking system that helps to make it easier for you to slow down and stop. Without it, you would have to exert a tremendous amount of pressure on the pedal. Instead, the booster creates a force of air or vacuum that balances out the high fluid pressure that exists in your vehicle's master cylinder.
It is a simple device that sits on the back area of the engine case, specifically between the master cylinder and the pedal. It works by multiplying the force that is applied to the brake pedal with its diaphragm. The diaphragm is a cylindrical piece of rubber. It has one side that is connected to the master cylinder and one side that is connected to the pedal.
When the pump is in working condition, it will create a constant vacuum that will help to press down the brake pedal. However, if the booster diaphragm is cracked or ruptured then it will be unable to provide the necessary force. In such a scenario, you will notice that the brake pedal is harder to depress and it may also take longer to stop your car.
If you suspect that your booster is failing, it is best to take your car to a repair shop as soon as possible. Driving with a failing booster can lead to uncontrolled acceleration, which could result in accidents and injuries.
Depending on the issue with your brake booster, there are different ways that you can check to see if it is actually broken. The first thing you should do is to remove the vacuum hose from the booster and fit it with a vacuum gauge. If the vacuum doesn't increase, it is most likely the hose that is the problem and not the booster itself. In some cases, you can even use a fuel hose as a temporary replacement.
The next way to check is to remove the brake booster from the chassis of your car and carefully look over it. If you are able to find a tear or crack in the rubber membrane, it can be repaired easily by patching it up. Moreover, you should also be able to see if the bleeder valve is open or closed.
It is crucial to examine your brake booster frequently because it is an integral part of your car's braking system. However, some people tend to overlook the signs that their booster is going bad. This can be a dangerous mistake because a failing booster can reduce your car's braking ability, which can lead to serious injuries and expensive repairs.
If you have noticed that the brake booster isn't working properly, you should visit a reputable auto service center for repair. The experts can diagnose the problem quickly and fix it before it causes serious damage to your car. They will also provide you with advice and tips on how to maintain your brake booster.
