Power brake boosters
provide assistance to the car’s braking system. So you won’t have to put in
extra force for the brakes to engage. The brake booster is generally located
between the brake pedal and master cylinder of car and it uses vacuum
to overcome brake pressure.
Brakes are very
important for your safety on the road. Any tempering with the brakes or its
functionality will result in accident because you won’t be able to stop the car
at right moment.
So if you notice that
your car is taking more than enough time to stall, brake pedal is difficult to
push, power brake booster is definitely failing. Don’t play with your safety.
You will find almost everything you need to know about Power brake boosters
here.
What
is a power Brake booster?
Power brake booster is
the device that is used to assist the car’s brake system as it reduces the
amount of force it takes to apply the hydraulic brakes. Mostly power brake
booster uses vacuum but some may use hydraulic pressure and use power brake hydraulic motor pump of car to accomplish this task of
braking.
Combined with the power of your foot pressing
the brake pedal, the shaft (which is pushed forward when the brake is
depressed) helps push a piston inside your brake master cylinder which in turn
displaces brake fluid through your braking system.
In a typical power
brake booster, the brake pedal is attached to the booster via mechanical linkage
(in case of vacuum) and brake master cylinder is bolted directly to its other
side. When the pedal is depressed, vacuum actuated plunger activates the master
cylinder.
How
do they work?
As you depress the
brake pedal, your pedal linkage causes a shaft to move forward in response to
your foot. As this shaft moves forward, it gets in touch with the master
cylinder and brake booster. The diaphragm in the brake booster divides it into
two parts with both in a partial vacuum.
When the brake pedal is
depressed, it causes the valve inside the booster to open which in turn makes
way for the air to enter one side of the booster. This difference of pressure
on one side helps to push the piston inside the brake master cylinder in
response to the brake pedal which in turn slows down the vehicle.
Without brake booster,
even simple act of slowing your car would require substantially higher amounts
of effort and incur greater amount of fatigue. So brake booster is a helping
hand for you.
There are auto remanufactured power brake boosters
and new auto power brake boosters
in aftermarket stores like parts avatar Canada. Choose your specifications and
buy one if you have worn power brake boosters.
Symptoms
of Failing Power brake boosters
It isn’t really a good
idea to drive a car with failed power brake booster. Though it is possible to
drive the car without properly working brake boosters but mind you it’s not at
all safe. It becomes very difficult and you will need to press the brake pedal
way too hard to stall your car.
It is wise not to drive
the vehicle with damaged power brake boosters. Following symptoms can alert you
if there is any problem with power brake booster of your car.
Hard
Pedal
It is the most common
sign of a failing power brake booster. If it is becoming hard to push the brake
pedal, brake booster is certainly a problem. The most obvious cause for the
hard brake pedal is simply not enough vacuum.
Do not drive a car with
hard pedal, as it would become too hard for you to halt your car with such
pedal condition and troubleshoot auto hard pedal problem.
Call your mechanic, and get your car’s brake system inspected thoroughly.
Replace your ruined
power brake boosters with new power brake boosters or even better you can use remanufactured power brake boosterwith master cylinder of car or remanufactured auto power brake without master cylinder after consulting with your mechanic and
friends.
Remanufactured items
are fully inspected of their warranties before they are added into the product
catalog at parts avatar by expert technicians. So if you want to buy
remanufactured products then do choose partsavatar.ca as your auto store.
Engine
Stalls
Not enough vacuum will
obviously result in hard pedal as read above. Failing power brake booster can
draw excess vacuum from the engine. If the diaphragm inside the brake booster
starts malfunctioning and allows the air to bypass the seal, the engine will
stall when the brakes are applied.
This is quite dangerous
as stalling engine can cause grave problems and there are various other causes of a stalled auto engine.
Avoid driving that car with such issues and waste no time in calling a
professional technician.
Longer
Stopping distances
As it becomes hard to
pedal, you won’t be able to get power assistance from failing power brake
boosters to stop your car. So, it will
take longer than usual to stop your car with much force and fatigue on your
side. It is dangerous if you are driving on highways or you are stuck in bad
weather.
As always, look for
your mechanic as soon as you discover this symptom.
Test
the booster at home
You can test your car’s
power brake boosters at home too. This will not be as risky as it is on the
road. With the engine off, all you need to do is to pump the brakes about five
to six times. This depletes the stored vacuum. Turn the engine on while pushing
down lightly on the brake pedal. If the brake booster is failing, nothing will
happen in this case and brake pedal will push back against your foot.
DIY
– Replace Brake Boosters
Replacing brake booster
is an easy task. You can take extra help while replacing old brake boosters
with new power brake boosters.
1. First step is to
disconnect the brake lines. Entire brake system is quite complex so start with
removing brake lines from master cylinder. Use the tube nut wrench to slowly
remove each line and mark it for easy identification when you are placing them
back.
2. After disconnecting
the brake lines, take out the master cylinder. You can also check the master
cylinder for any sign of damage.
3. The brake booster is
connected to the brake pedal. Using wrench unfasten the bolts that attach the
brake booster to the engine and remove it completely.
4. Place the new brake
booster to its place and secure it with bolts. Reconnect it with diaphragm,
engine and brake pedal. Now in the reverse order, reconnect the master cylinder
and then the brake lines.
So never ignore any
symptom that alerts you for failing power brake booster. And do yourself a favor
and use other safe means of transport other than the one with failed power
brake booster for your safety.
