The objective of a brake booster is to provide power assistance to the braking system, so you don’t have to exert as much effort to get the brakes to engage. The brake booster uses a vacuum to overcome the braking system’s fluid pressure. It is located between the brake pedal and the master cylinder.

If the brakes are not working properly, the automobile should not be driven. Because the brake booster is such a vital part of the braking system, keep an eye out for the following eight symptoms so you can have it replaced right away:

1. Use a firm brake pedal.

The main indication of a defective brake booster is an extremely difficult-to-push brake pedal. This issue may appear gradually or suddenly. Furthermore, the brake pedal will not return to its original position after being pressed. As soon as you notice your brake pedal is difficult to engage, contact a qualified technician to get your brake booster replaced.

Defects in brake boosters must be repaired as quickly as possible; driving a car with a malfunctioning brake booster is extremely risky. This will be clearly stated as a reason for MOT test failure if you use an online MOT history checker.

2. Increased stopping distance If you have a stiff brake pedal, the automobile may take longer to come to a stop. This is because you aren’t getting the sufficient power increase to successfully stop the vehicle. A longer stopping distance may be risky in any conditions since it makes your car unreliable. Have it checked out by a technician as soon as you notice the problem. When you ‘check my MOT history’ online, another common reason for a MOT test failure is the braking system.

3. When the brakes are applied, the engine stalls.

When the brake booster fails, the engine may lose too much suction, causing the engine to stall. This occurs when the diaphragm of the brake booster fails, enabling air to bypass the seal. The brakes are then applied, the engine appears to be going to stall, and the idle may be reduced. In addition to reduced braking effectiveness, a stopped engine can cause serious issues. Check your car’s MOT status and have a professional fix the fault, since a failed MOT will occur.

4. The use of a high brake pedal

When you remove your foot off the brake pedal, it may travel less than usual or take significantly longer to return to its original position. An imbalance in the vacuum chambers of a failed vacuum brake booster might be the source of one of these problems.

5. A hissing noise You may hear a hissing sound when you press the brakes. The vacuum booster’s diaphragm or casing may be leaking, or the vacuum hose may be leaking.

6. Engine operations are restricted A faulty engine operation is another possible sign of a vacuum leak. Assume your diaphragm has a hole in it or your vacuum check valve is malfunctioning, enabling air to enter your system. This air might affect the fuel mixture in the engine. Improper fuel mixture lowers gas cooling, increasing friction and temperature of engine components.

When the gasoline ignites before the spark plug fires, this is known as pre-ignition. Preignition can cause piston damage or a burnt valve, both of which would demand expensive repairs. If you review your car’s MOT history, a failed emissions test on a MOT might be the result of this.

7. The warning lights illuminate.

If your vehicle is equipped with an electronic brake booster, its failure might cause the anti-lock braking system to malfunction (ABS). As a result, your brake warning lights, such as the ABS, stability control, or traction control lights, will illuminate.

8. Leakage of Fluid Fluid leaks might indicate a number of problems with your car. Your hydro-boost component is prone to break if your automobile has hydraulic boosters and is leaking power steering fluid. Electronic brake boosters that are connected with the master cylinder may be affected by leaks as well.

Have your automobile evaluated by a professional if the brake pedal is difficult to press or your car is taking longer to stop. This will assure your safety on the road. If required, the mechanic will fix your brake booster as quickly as possible so that you can go back behind the wheel safely. #carservicesinreading
