Brakes are extremely important
components of any vehicle for save driving, while it is necessary to solve any
issue related to the engine but breaks are even more important parts of the
vehicle because brakes control the speed of your vehicle and aid vehicles to
slow down. In the modern vehicle, the hydraulic brake system is installed in
the vehicle to manage the brake of each tire. Some vehicles have front tires
with disc brake and rear with drum, but in new models of vehicles mostly all
tires have disc brakes. When you press down the pedal, the front breaks play an
important role in slowing down the vehicle as compared to the rear brakes
because when you apply for brakes the weight of the vehicle pushes it forward.
Common Causes of Noise and Vibration When Braking:
When you drive your vehicle and
apply breaks or even before applying brakes you may hear strange noises like
rubbing, metal scrapping or grinding, it indicates that your brake system may
have a serious issue that you needed to address. Sometimes without having any
problem with the brake system, you might hear some noise but go away on its
own. But if the sound remains persistent and become even worse with the passage
of time, it gives a clear sign that your brakes have some sort of issue. We will
discuss here are the 9 most common reasons for noise produced from the brakes.
(1) Worn Brake Pads:
When you step on the brake pedal
and you start hearing grinding noise loudly then it indicates that your vehicle
brake pads are worn out. It happens when the material on the backing plate
losses and the metal surface of the brake pads come in contact with the metal
on the rotor, it could heavily damage the brakes of your vehicle if you don’t
replace the pads and continue driving in a condition like this. The backing
plate of the brake pads will destroy the rotor as a result of grooves in the surface of rotor forms and also make the surface of the rotor uneven.
(2) Bad Quality Brake Pads:
Always use brake pads which are
recommended by your vehicle manufacturer, don’t try to save money by purchasing
low quality of brake pads. Using low quality of brake pads gives a poor
performance at high speed which can cause a serious accident that further leads
to fatal injuries. Cheap brake pads have metal chunks in their material and are
poorly manufactured; these metal chunks scrape with the surface of the rotor as
a result damage the surface of the rotor and make the surface of the rotor
uneven.
(3) Worn Shims:
When you replace the brakes of
your vehicle by yourself or get a job done by a mechanic, never forget to
replace the shims. Mostly mechanic doesn’t replace the shims because they try
to save time as they wanted to deal with more customers that’s why make sure
that the mechanic replaces shims each time you replace the brakes of your
vehicle. If you won’t replace the shims they will wear out with age, worn shims
make contact with the surface of the rotor or other parts of the brake system.
Due to the contact of the shims with the brake system, you will hear sounds
when you apply brakes to slow down your vehicle. So make sure that you replace
shims each time when you replace the brake pads.
(4) Debris Stuck in Brakes:
If you ever drive your vehicle
off-road, it might be possible that debris gets stuck in your vehicle brake system.
The debris could be gravel or a piece of stone that stuck between the rotor and
caliper, and causing the grinding or scraping noises to occur. The noise will
not stop and you will continue to hear even if you are not applying brakes to
slow down the vehicle, if you didn’t remove the debris and continue driving
like this it could damage the surface of the rotor, as a result, you need to
resurface the rotor or possibly required to be replaced. Sometimes if debris
stuck in your vehicle it causes misalignment of the brake pads which cause poor
performance of the brake pads and then it will be necessary to replace the
brake pads sooner than normal.
(5) Infrequent Driving:
Brake pads usually last from
30,000 to 70,000 miles driving normal, but it also depends on the driving style
of vehicle and type of vehicle. If your vehicle brakes having issues sooner
then it simply means that you are not driving your vehicle enough. For example,
if you stored your vehicle for the winter and your vehicle brake rotors don’t get
used for a long time it will eventually start rusting and get even slightly
corroded with a rough surface. Other components of the brake system will also
get corroded therefore you may also have an issue to calipers sticking in your
vehicle. You can avoid this issue by driving your vehicle little on a daily
basis so that the surface of the rotor will not get rusty.
(6) Caliper Bolts:
Caliper bolts of the brake can
require lubrication for smoothly working if they get dry and their slides
create sounds. It is a very rare scenario less likely to occur, but it is also
a factor that can cause noises in your brake system. A good reputable repair
shop must lubricate the bolts and even replaced them if they get too rusty.
(7) Faulty Wheel Bearings:
This is the least likely issue
that occurs for having brake noises if you feel the vibration with the
grinding noise from your wheels and you experience sound from loud to quiet
then it indicates that you are having a bad wheel bearing which is needed to be
replaced as soon as possible. With the noise, you will also experience
vibration in your steering wheel while driving the vehicle at high speed.
