Why will cause brake abnormal sound ?
The braking systems is one of an important its systems work in a very bad environment,
if the system fails, the car can be compared to a wild horses, there will be dangerous at any time.
Therefore, we recommend that you inspect and maintenance the braking system regularly.
Now the majority of drivers always attach importance to the braking system very seriously,
but often not understanding deeply, even the emergence of a number of anomalies,
such as: braking abnormal sound, deviation, the lack of braking force, soft brake pedal,
brake wear, such as abnormal And so on. The causes as below:
1, The normal wear and tear of the powder of brake pads is retained in the vicinity of the wheel cylinder, it will not cause abnormal sound because not clean-up for a long time.
2, on the gravel road, some particles will splash down between the brake pads and discs, causing abnormal sound or unusual wear.
3,The muffler tablets and damping tablets of brake pads be lubricated uncleanly for a long time, it will cause abnormal braking sound.
How long should my brakes last?
Depending on the application brake pads should last
anything from 20,000 to 70,000 kilometres. If you feel
that your brake pads are wearing out prematurely you
may need to have your mechanic install heavier duty,
temperature resistant brakes pads such as NGBBP.
The main cause of premature wear is high temperatures.
Steep terrain, towing of heavy loads and constant braking
all increase braking temperatures and reduce the life of brake pads.
Why are my brakes noisy?
Brakes should operate with a minimal amount of noise.
Some noise is normal, but excessive squeal, screech,
grinding, groaning or banging means that your brakes
need attention. Using the wrong formulation for your
driving style can also cause noise in your brakes due to excessive heat.
There¡¯s a terrible vibration when I brake. What causes that?
If the brake pedal, steering wheel or the entire vehicle shakes,
vibrates or pulsates when the brakes are applied, then
the disc brake rotors may need resurfacing. More serious problems
such as a loose component or a faulty steering mechanism can also cause vibration.
When brake pads are wearing out too quickly. What should I do ?
First, check the car's odometer reading to see if the calipers
have ever been overhauled. Driver abuse can also cause rapid wear.
When the rear brakes are not doing their share of braking,
rapid wear of the front brakes will result. Check to see if
the booster/master cylinder/proportioning valve are out of adjustment.
Calipers must be overhauled at 60,000km intervals.
Find out which friction material has been fitted as it
may be wrong for the application. Overhaul if necessary.
How to deal with differences in pad wear ?
Uneven pad wear is often a caliper problem, caused by faulty seals,
sticking or bent slide pins. Overhaul the calipers on that axle.
Why brake pads smoke sometimes and often give off a strong smell ?
The brake pads are simply getting too hot. The most common causes are
driver abuse or faulty calipers. Faulty calipers may cause
the front or rear brakes to 'hang on', building up heat
in the friction material. Get the driver to change his driving habits.
Overhaul the braking system.
What can be done to eliminate steering vibration under braking?
Disc thickness variation is the cause of this problem.
Usually it is caused by the disc being out of alignment
when originally fitted. Machine the discs. If they are
thinner than the manufacturer's minimum thickness specification,
replace the discs.
How to deal with when poor braking performance after disc machining ?
Brake pads frequently get blamed for this. The real culprit
though is incorrectly finished discs. After machining, always
clean off the disc surfaces with 240 grit emery. Then clean up
using a non oil based solvent. Repeat the process after fitting.
A thorough wipe down will remove graphite and grease.
What is DTV?
Disc thickness variation (DTV) is where the rotor or disc varies in thickness,
as indicated in the diagram, around the rotor
