How To Diagnose A Bad Brake Caliper

How To Diagnose A Bad Brake Caliper
It is common for many people to go to a machinist explain that they have problems to brake their vehicle, thinking that they should change the whole system, when the trouble may be good the brake caliper .
Hence, the importance of knowing how to diagnose a bad brake caliper, so here we will give you the answer to this and many more questions on this subject .

What Are The Symptoms That The Brake Caliper is Failing?

The signals that show that the brake caliper has problems are the pursuit :

Escape from brake fluid

When the brake calipers have problems it is normal to see how the brake fluid escapes, this, because the calipers work with the help of the atmospheric pressure of that liquid .
therefore, the dominate cylinder in which the tweezers operate has gums that allow the liquid does not escape, but over time, the wear, function, and inflame generated by the constant brake rubber seals they release or lose pressure, causing the liquid to spill .
The above will not merely cause the lapp escape of liquid to damage the protective rubber but besides, in the absence of sufficient press, the braking capacity of the car is well reduced .

Pulling the car sideways

A vehicle with a adept brake system and with the braking caliper in full condition brakes mechanically when placing the metrical foot on the brake pedal point, but if the vehicle turns to the right or to the left when brake, that is a polarity that the brake caliper is in bad circumstance .
This happens because the heat to which the brakes are subjected by friction can affect the grip capacitance of the caliper piston .

In fact, a clamp piston with this problem can not be retracted, consequently, there is a drag of the wheel when brake .
then, the car will pull or pull to the side where the trot is in hapless discipline .
besides, the driver will notice that one steering wheel is slower than another because of the impossibility of brake .

Rare sounds

Those who know their car very well, are very clear of the normal noises and the abnormal noises of their cars .
Hence, detecting that a peg brake is failing is simple, barely listen to a sudden blow when braking to detect that there is a problem .
Regarding these noises, you have to be very alert, since a loose, tangled clamp or one that is not well attached to the braking system american samoa well as reducing the serve life of the brakes, can cause problems to stop the fomite, which can generate a serious accident .

Vehicle vibration

If when braking the steering roulette wheel vibrates or the brake pedal vibrates, it is necessary that it be attended to quickly, as it is a symptom of damage to the brake arrangement that may be directly related to the brake caliper .

Causes By Which The Brake Caliper Can Be Damaged

The causes for which the brake caliper can be damaged can be very varied, among them are

Old brake fluid

The brake fluid must be replaced frequently ; it is advisable to at least change it every 3 months .
The brake fluid that is not changed frequently does not fulfill its lubrication functions correctly, therefore, this generates the oxidation of the piston walls .
so, if the brake fluid is not renewed, the corrosion produced can cause the brake arrangement to collapse when the mechanism is locked and will besides cause the piston to degrade .
In twist, the brake fluid used absorbs moisture which is another causal agent of the corrosion of the piston walls.

In addition, the old fluid is dirty, cold and can generate cracks in the brake system, which can besides degenerate into wrong to the piston .

Brake pads worn

Another cause why the brake caliper may be damaged is that the brake pads are not replaced .
In fact, every clock the brake pads are replaced, it is necessary to check the bang area very well, because if the area is in dear condition .
The protective covering of the brake pads and consequently the protection of the brake pads are guaranteed bracken caliper .
In turn, we must take limited wish in changing the brake pads to lubricate the pins, keep in mind that on these pins is that the caliper slides .
consequently, it is necessity to constantly find sufficient lubrication to prevent dust and water from disturbing the brake capacity .

Deterioration of the brake caliper

The enactment of time wreaks havoc on any mechanical firearm .
And while it is significant to maintain the brake system constantly, it is besides authoritative to check the brake caliper and consider replacing it if necessary .
Every mechanical part has its utilitarian life, consequently, the brake caliper besides .
indeed, depending on the use you give to your car and according to the year of the car, consider a review to the brake caliper .

Breakdown of the brake caliper

just as a brake caliper wears out, it can besides be damaged. fortunately, today ’ second cars have sensors that can warn the driver of a problem in the brake system, which besides implies the notice of a problem with the brake caliper .
therefore, if your car issues an alert or lights a light on the dashboard that warns of a brake failure, do not hesitate to stop the fomite immediately and contact your mechanic or trusted specialist .
then, if the blame is in the clamps, logically it will require a substitution of them .

Solutions to failures with the brake caliper

The solutions depend on the problem that occurs with these, among the possible solutions are :

  • If the problem is queueing the brake fluid, you must replace it or put enough for the system to work properly.
  • If the problem is with the master cylinder tires, they must be replaced so that there is no brake fluid leakage.
  • If the problem is with the brake pads, they must be rectified or replaced so that they do not cause further problems affecting the calipers.
  • If the problem is damage or deterioration of the clamps, the solution is definitely to replace them immediately.
  • Check the braking system every 200,000 kilometers, thus avoiding future problems.

Frequent questions of How To Diagnose a Bad Brake Caliper

Why is a brake caliper adhere ?

  • Because of the humidity.
  • Because of the dirt.
  • For not using a good liquid or lubricant.
  • By deformation of the own clamp of wear.
  • Due to radical changes in temperature.
  • For driving with worn pads.
  • By exposing the car to chemicals or abrasives that reach the brakes.

What can I do to extend the life of the brake caliper ?

  • Do not drive abruptly and suddenly brake steadily
  • Change the brake pads every 6 months
  • Apply a special liquid to the clamp to make it more resistant to heat
  • Applies anticorrosive liquids preventatively to the clamp

What can I do if the brakes fail in my cable car while I drive ?

  • Release and press the brake pedal continuously, this can reactivate the system and generate pressure
  • Try to break the vehicle with the engine through the change of speeds
  •  It seeks to leave the road and enters the emergency braking zones
  • Do not go to the hand brake quickly, you can lose control of the vehicle
  •  Never turn off the engine of the car so you will not stop your progress

never forget to constantly check the brake caliper, this is an important element of the brake system, so constantly have it checked by a technician or specialist machinist, in this manner you can determine in time if you need sustenance or successor .
