9 Common Failures of the Brake System & How to Repair Reliably at Thanh Phong Auto Garage Hcm 2024
Latest update date: February 11, 05

During operation, the brake system is one of the most important and complex structures of a car. With the task of ensuring safety for the driver and passengers, the brake system always faces strong impacts from friction, high temperature, and great pressure. This causes system components such as brake discs, brake pads, brake fluid, and brake cylinders to be easily damaged or worn out over time.

According to a study by Bosch, a leading auto parts manufacturer in the world, about 17% of road traffic accidents are related to brake system failure.

Common problems in the brake system include brake disc tire wear, brake fluid leaks, stuck or damaged brake cylinders, and loss of braking performance due to sediment or gas in the brake fluid. Additionally, problems such as vibration when braking, strange noises from the brake system, or the vehicle dragging can all be signs of a problem in the brake system.

The following article Thanh Phong Auto Please send to you the 9 common damage of the brakes and the simplest way to repair, to achieve the best performance. Along track the following article!

Low brake oil level

The case when the level phenomenon occurs Car brake fluid The low may be due to an internal leak of the system or a worn-out brake pad. If it is caused by a leak, the brake light on the tap will light up at this time. In the brake system when a leak occurs, it is dangerous because the worst case scenario that can happen while the vehicle is in motion is the brake not eating.

The details that need to be checked now are the cylinders, brake lines, brake cylinders on the wheels and brake shackles. Damaged parts should be replaced if leaks are found. Never use a vehicle before the problems are fixed and repaired.

Brake pedal low

When the brake pedal adjustment bar is stuck on the rear wheels or the brake pads are adjusted incorrectly, a low brake pedal phenomenon may occur. Now to restore the height of the brake pedal, you just need to reinstall the brake pad adjustment bar.

Light brake pedal

Some causes of light brake pedals include:

  • The exhaust procedure in the brake system is not correct
  • Brake fluid is low
  • In the brake system contains air

To be able to fix the pedal error quickly and easily, simply add a little brake fluid to the system or take steps to release the wind again.

Reasons Why The Brake Pedal Is Too Light
There are many causes of a brake pedal that is too light

Large brake pedal travel

Some possible causes for a large pedal pedal include:

  • Incorrect setting of brake pads height in the rear wheels
  • In the brake system contains air
  • The rear brake pads and front brake pads are worn

If this is the case, you can tell very simply because your brakes will not eat, or if the brakes do eat, you need to step on the Pedal brake more.

Car brake pedal vibration

If you feel the vibration of the brake pedal while you are driving, it could be due to the irregularity of the brake pads and disc. Now you just need to review the brake discs or immediately replace the brake pads to make them fit together.

When braking, noise is made

Once the brake lining has worn out and the brake pads only remain hard material inside, it shows that the brake pads are worn out. At this time you apply the brake pedal, the brake disc and the brake pads will rub against each other and emit an extremely hard to hear. In order for the brake disc not to wear quickly and do not appear scratches, you should immediately replace the brake pads.

Brakes Make Noise Due to Worn Brake Pads

When braking, the car jerks to one side

When the feeding of the two front wheels is not equal, the phenomenon of causing the car to crash aside when braking will occur. This may be because the brakes on the right wheel eat more than the left and vice versa. The height of the brake pads of the two front wheels you adjust are not equal or when braking a wheel is stuck, it will cause the car to be pushed aside.

To be able to overcome and repair this problem is not too difficult, you just need to check to see if the wheel cylinder is stuck or not? or adjust the brake shoe height of the two front wheels.

Car Brakes
The car's brakes are shifting to one side due to uneven wear on both sides

The brake pedal is stiff

In order to help support the braking force, there is usually a brake assist mechanism, so you do not need to exert too much force on the brake pedal, but now the brake is still eating and operating normally.

When the pedal has a stiffer phenomenon, the brake force is broken. When this happens, you may need to immediately replace the new brake force or should check whether the vacuum hose of the brake force is good.

Lock the brakes

Braking occurs due to problems in brake operation such as: incorrect adjustment of the handbrake, incorrect foot brake, damaged brake pad springs, cylinder jam, master cylinder failure, dry battery oil, etc. Although the driver has Stop applying force on the brake pedal but the brake still won't release.

The situation of brake lock is quite common, so car drivers need to catch the signs to have a quick and effective remedy.

Note when repairing car brake system

Brake pads are one of the most important parts in the car brake system, they help the braking process safely and greatly determine the stopping speed of the vehicle. After a period of use, car brake pads will gradually wear out, become damaged and need to be replaced promptly. Therefore, you need to pay attention to the following points:

Knowledge About Car Brake Pads
Car Brake Pads

Bad habits cause brake pads to wear quickly

Brake pads wear out due to the following reasons:

  • The brake is folding and the brake is jerky, which causes the brake pads to wear quickly, and damage the brake clamp.
  • Checking the brake on a slope will cause the brake temperature to rise and cause damage. In particular, when the brake pad temperature reaches 600-700⁰C, it will cause brake loss and easily cause an accident.
  • Frequent overloading also affects brake braking and reduces brake life.

Indication of a damaged brake pad

Signs of damaged brake pads include:

  • Brakes are misaligned: If the car tends to misalign (left or right) when braking, the brake pads may be damaged. If not replaced, loss of control will easily occur.
  • Warning of wear sensor: Car brake pads are often equipped with a sensor. When the brake pads are worn beyond the standard, the sensor will give a warning.
  • Some other signs such as: Brake pedal has no force, Hard brakes, Locked brakes, Loss of brake grip,...

If you notice signs of damage to the brake pads, you should immediately go to the garage to have it checked for safety.

Pay attention to when to check - replace brake pads

Even if you use your vehicle carefully and do not see any signs of brake damage, you should check your car periodically according to the following milestones:

  • After 80.000km or after 2 years of using the car.
  • Check earlier if using a car in a densely populated area with frequent traffic jams.
Advantages and Disadvantages of Types of Car Brake Pads
Types of Car Brake Pads

Note, on the market there are quite a few types of brake pads for cars such as:

Commonly used types of car brake pads include: metal brake pads, ceramic brake pads, and organic brake pads:

  • Metal brake pads: made from metal, works well even at high temperatures.
  • Ceramic brake pads: made from copper and ceramic fibers mixed together, good to use and highly durable.
  • Organic brake pads: made from non-metallic organic fibers, use smoothly and make little noise.

Depending on the needs of use as well as the economic conditions, you should choose the right brake type.

Most frequently asked questions about car braking systems

1. How often should the brake system be inspected and maintained?

You should periodically check your car's brake system every 10.000 - 15.000 km or every 6 months, depending on vehicle usage conditions. If you frequently travel in crowded urban areas, you should shorten the inspection cycle to 5.000 - 10.000 km. Read the article now to share everything about it car brake/braking system most detailed.

2. What is the average lifespan of car brake pads?

The lifespan of brake pads depends on the material and conditions of use. Typically, metal brake pads have a lifespan of about 60.000 - 80.000 km, ceramic brake pads about 80.000 - 100.000 km, and organic brake pads about 40.000 - 60.000 km. However, if you frequently brake suddenly, brake jerkily or are overloaded, the life of the brake pads will be significantly reduced.

3. How to deal with brake lock on the road?

If you encounter a brake lock situation, you need to calmly handle it by following these steps:

  • Take your foot off the accelerator and hold the brake pedal and steering wheel firmly
  • Set the gear to position N (forward gear)
  • Turn on hazard warning lights
  • Stop your vehicle safely on the side of the road or in an open space
  • Call emergency services to check and handle the problem

4. What is the minimum and maximum brake fluid level in the reservoir?

The minimum and maximum brake fluid levels are usually clearly marked on the tank wall. Normally, the minimum brake fluid level is the “MIN” or “LOW” line, and the maximum level is the “MAX” or “FULL” line. The brake fluid level should always be maintained between these two lines.

5. Should you arbitrarily change brake fluid at home?

Do not arbitrarily change brake fluid at home if you do not have specialized knowledge and tools. Changing brake fluid incorrectly can cause air in the brake system, making it dangerous to use. Ideally, you should take your car to a professional garage to have the brake fluid checked and changed safely and technically.

6. Can you check the wear of brake pads yourself?

You can check brake pad wear yourself by:

  • Observe through the wheel gap: If you see the brake pad layer is less than 3mm thin, you need to replace the brake pad with a new one.
  • Listen for braking noise: A harsh screeching sound when braking is a sign that the brake pads are worn beyond the allowable limit.
  • Check the indicator light on the dashboard: Some cars are equipped with sensors to indicate brake pad wear. When the brake pads are worn to the limit, the indicator light on the dashboard will light up.

7. How to prolong the life of car brake pads?

To prolong the life of your brake pads, you need:

  • Avoid sudden braking or jerky braking
  • Slow down slowly before braking
  • Avoid braking continuously when going downhill
  • Do not overload more than recommended by the manufacturer
  • Check and maintain the brake system periodically

8. What are the signs that the brake booster system is having problems?

Some signs of a problem with the brake booster system include:

  • The brake pedal is harder or heavier than usual
  • Brake pedal travel is longer than usual
  • There is an unusual screeching or noise when applying the brake
  • The vehicle moves to one side when braking

9. Can deformed brake discs self-recover?

No, deformed brake discs cannot be repaired on their own. At this time, you need to take the car to the garage for convenient inspection and replacement of new brake discs if necessary. Using deformed brake discs can cause the vehicle to vibrate when braking, even causing loss of control and leading to an accident. Additionally, you can refer to the article: Causes & signs of warped car brake discs most effective and simple.

10. Should brake pads and brake discs be replaced at the same time?

If only the brake pads are worn out while the brake discs are still good, you only need to replace the brake pads with new ones. However, if the brake disc is thin, deformed or cracks appear, both the brake pad and brake disc need to be replaced to ensure safety and optimal braking performance. Normally, brake discs have a longer lifespan than brake pads and only need to be replaced after 2-3 brake pad changes.

11. Is it necessary to replace brake pads for all 4 wheels at the same time?

Experts recommend replacing brake pads for all four wheels at the same time to ensure balanced braking force and avoid the vehicle skewing when braking. Replacing brake pads for only 4 or 1 wheels can cause the vehicle to lose balance, affecting operating safety, especially in slippery road conditions.

12. What are the dangers of using fake, poor quality brake pads?

Using fake, poor quality brake pads can cause dangers such as:

  • Reduces braking efficiency, causing longer braking distances
  • Wears out quickly, even peels off during use
  • Causes damage to brake discs due to uneven friction
  • Affects other details in the brake system
  • Potential safety risk when operating. Therefore, you should choose genuine brake pads or from reputable brands with guaranteed quality to replace your car.
