5 Warning Signs Your Car’s Brake Booster Is Failing

A car’s brake booster is one of the most overlooked components in automobile safety. Yet, it also has some of the most far-reaching effects on your car’s performance when it fails. So if you’re experiencing any of these five warning signs that your car’s brake booster is failing, consider bringing your vehicle into the shop to have this component replaced before you’re put in harm’s way. 

1) ABS Light

One of the first signs that your brake booster is failing is when the ABS light comes on. This is because the brake booster helps control the pressure in the braking system, and when it starts to fail, the pressure can fluctuate, triggering the ABS light. If you see this light come on, it’s vital to get your car checked out by a mechanic as soon as possible.

2) Increased Braking Distance

If you notice that your car is taking longer to stop than usual, this could be a sign that your brake booster is failing. The brake booster is responsible for providing extra power to the brakes, so if it’s not working correctly, it can take longer to stop. If you’re concerned about this, be sure to have your car checked out by a mechanic.

3) Brake Pedal is Very Stiff

If your brake pedal is stiff, it could be a sign that your brake booster is failing. When the brake booster fails, it doesn’t provide enough vacuum power to the brakes, making it difficult to press the pedal. Sometimes, you may even need two feet to push the pedal down. If this is happening, you should take your car to a mechanic to have it checked out.

4) There is Fluid Leaking From the Master Cylinder

If you notice any brake fluid leaking from your master cylinder, it’s a sign that your brake booster is failing. This is because the booster relies on hydraulic pressure to function correctly. When there’s a leak, that pressure is reduced, and the booster can’t do its job as effectively. As a result, you may notice longer stopping distances or a complete loss of braking power. If you suspect a leak, have your mechanic check it out as soon as possible.

5) Engine Stalls When Braking

If your engine stalls when you brake, it’s a sign that your brake booster is failing. The brake booster is a vacuum-powered assist that helps with braking power. If it fails, it will draw excess vacuum from the engine, stalling when applying the brakes. 

If your car’s brake booster is failing, you will have a hard time stopping your vehicle, which can be dangerous. See your mechanic at the first sign of brake trouble to get it diagnosed and fixed.
