Symptoms of Brake Booster Failure in Cars
2
A car's brake booster uses the engine's vacuum to
strengthen the force of a driver pushing his foot
on the brake.
3
It is located between the brake pedal the
master cylinder, and when the brake is pressed,
the booster amplifies the force applied by the
driver.
4
When the booster malfunctions, then the driver
has to apply a lot of force to depress the brake
pedal in order to stop the car.
5
All modern cars come equipped with a brake
booster and it is important to the functioning of
the power brakes at all times.
6
Here are the tips, which will help you in
handling the brake booster failure in your car.
7
Brake pedals fail
8
A driver first detects the brake booster issue
when holding the brake pedal while starting the
car.
9
This indicates the brake booster suffering from a
fluid leak, due to a worn out car hose,
automobile valve, or car piston.
10
Doing a diagnostic test will determine the exact
faulty component responsible for this brake
booster issue.
11
Vaccum failure during acceleration
12
If the vehicle suffers from a vacuum failure when
the engine accelerates then it indicates that
something is wrong with the check valve.
13
If the problem persists after the check valve is
replaced then you must replace the brake booster
of your car.
14
Brakes feel spongy
15
As the problem with the vacuum brake booster
increases, the air bubbles will progressively
move down the brake lines to the brake
themselves.
16
This causes a reduction of pressure inside the
brake lines and can cause the brakes to be
applied softly.
17
While driving, you will feel as if the brake
pedal is spongy, and the brakes will also take
longer to stop the vehicle.
18
Miscellaneous symptoms of booster failure
19
If the brake pedal doesn't return completely to
its original form, then it indicates that the
brake booster spring has broken.
20
If you hear abnormal sounds when you apply the
brake, it might be related to the malfunctioning
of the brake booster push rod.
21
The worst case scenario happens when the vacuum
brake booster check valve completely breaks and
leads to a complete brake system failure.
22
Conclusion
23
The braking system of the vehicle is the most
important part to be related to the safety of the
driver occupants.
24
The vacuum brake booster check valve is an
integral part of your car's braking system and
acts as a safety feature.
25
If you experience any of the above-discussed
problems, then immediately take your car to the
nearest automotive repair shop.
