A power brake booster is an essential component in any modern
car's braking system. It enhances the braking power and reduces the amount of
effort required to stop the vehicle. When it fails or malfunctions, the
consequences can be severe, and the safety of the driver and passengers are at
risk. In this article, we will explore the symptoms of a failing or
malfunctioning power brake booster, and how to detect it using the "check MOT history"
service.
Symptoms
of a Failing or Malfunctioning Power Brake Booster
Hard
Brake Pedal
One of the most common symptoms of a failing or
malfunctioning power brake booster is a hard brake pedal. When the brake
booster is not working correctly, it can cause the brake pedal to require more
force to stop the car, making it harder for the driver to brake efficiently.
The brake pedal may feel stiff or unresponsive, making it difficult to slow
down or stop the vehicle.
Longer Stopping
Distance
A malfunctioning power brake booster can also cause the car
to have a longer stopping distance. When the brake booster is not functioning
correctly, the car's braking power is reduced, and it takes longer for the car
to stop. This can be particularly dangerous when driving at high speeds or in
emergency situations, where the extra distance required to stop can cause an
accident.
Spongy
Brake Pedal
Another symptom of a failing or malfunctioning power brake
booster is a spongy brake pedal. When the brake booster is not working
correctly, it can cause air to get into the brake lines, leading to a soft or
spongy brake pedal. This can make it difficult for the driver to apply the
brakes efficiently, as the pedal may feel like it is sinking or not providing
enough resistance.
Hissing
Noise
If you hear a hissing noise coming from the brake booster
when you depress the brake pedal, it could be a sign that the brake booster is
failing. This noise indicates that air is leaking into the brake booster,
causing a loss of vacuum pressure, which can affect the car's braking ability.
Detecting
a Failing or Malfunctioning Power Brake Booster Using "Check MOT
History"
The "check MOT status"
service is an online tool that allows car owners to check their vehicle's MOT history. MOT is an
annual test that all vehicles in the UK must pass to ensure that they meet the
minimum safety and environmental standards. When using the "check MOT
history" service, you can look for any issues that may have been flagged
during the vehicle's MOT inspections, including problems with the brakes or
brake booster.
To use the "check MOT history" service, you will
need to enter your car's registration number on the website. The website will
then display the vehicle's MOT history, including any advisories or failures.
If your car has failed an MOT due to a problem with the brake booster, it is
essential to address the issue as soon as possible to ensure your safety on the
road.
If you are buying a used car, it is also a good idea to use
the "MOT history check”
service to check the car's brake system's condition, including the power brake
booster. This can help you avoid purchasing a car with significant brake issues
that could put your safety at risk.
Conclusion
A failing or malfunctioning power brake booster can have severe consequences and affect the safety of the driver and passengers. Symptoms of a failing power brake booster include a hard brake pedal, longer stopping distance, spongy brake pedal, and hissing noise. The "check MOT history" service is a useful tool that car owners can use to detect issues with their car's brake system, including the power brake booster. By addressing any problems with the brake system promptly, you can ensure your safety on the road and prevent accidents from
