What causes brake failure?

Knowing when to replace your brake pads is important, however, knowing what causes them to fail is equally crucial. If you think your brakes are broken while on the road, do not continue driving. It might cause a serious accident. It’s best to get to the side of the road as safely as possible and get help. To avoid this from happening, here are the most common causes of brake failure that you have to know:

  1. Loss of brake fluid 

The brake fluid provides the force created when you press the brake pedal. This force is applied to each of the brake rotors on the four corners of your car. When pressure is applied effectively, the wheels slow or stop the movement of the car.

If there’s a leak in your brake fluid, it can cause a loss of brake pressure which means your car won’t be able to stop. You’ll know if your brake fluid is leaking when there’s liquid dripping from your engine down to the floor. If you notice a leak, get it repaired and replaced first before driving.

  1. Damaged brake cylinder

The brake cylinder is a hydraulic pump that feeds brake fluid into the brake circuit to convert the pressure on the brake pedal to hydraulic pressure. A bad brake cylinder can cause your braking system to lose power.

If the brake fluid is leaking past the seals inside the cylinder, your brake pedal may feel firm for a moment but it won’t hold steady. You will start to feel it go spongy, and mushy, and may sink far down when pressed.

  1. Bad brake booster

As the name suggests, a brake booster helps to boost the performance of your brakes. This makes it easier for you to brake by increasing the force exerted without the need for the additional force applied on the foot pedal.

If the brake booster fails, it loses the ability to amplify the force from your foot. This means you’ll have to use more effort when stepping on your brake pedal. This can reduce the hydraulic pressure in the brake fluid, making it harder to brake.

TOP TIPS TO CARE FOR YOUR CAR’S BRAKE SYSTEM

The health of your brake system is crucial to the performance and safety of your car. Poor brake system maintenance not only compromises the efficiency and longevity of your vehicle, but is also a major cause of road accidents.

The brake system is somewhat complex, but fairly easy to maintain. It is critical that you have your brake system inspected regularly and necessary repairs done on time. Some of the key components in the brake system include brake pads, brake lines, master cylinder, rotors and calipers.

Key Brake System Maintenance Tips

1. Have Brake Pads and Rotors Checked Regularly

Due to its nature of operation the braking system endures a lot of wear. Brake pads and rotors form the point of contact between the braking system and the tires. These two components wear more quickly and hence require more attention and maintenance. Brake pads endure a lot of heat which causes a lot of wear. It’s critical that you use high-quality brake pads that offer sufficient resistance to wear.

If you notice you need to apply a lot of pressure to your brake pedal, an increase in your stopping distance or a burning smell you need to have your brake pads and rotors checked.

2. Get a Brake Fluid Flush

When you step on your brake pedal, pressure builds up and is transmitted through brake fluid from the master cylinder, via brake lines and into the calipers. These in turn transmits this pressure to the brake pads and rotors. Brake fluid is therefore a critical component of the braking system since it acts as the messenger of the braking system.

Unfortunately, with time it attracts moisture, which can damage your braking system. This moisture corrodes the metal components of the braking system, reduces the boiling point of the fluid hence compromising the effectiveness of the braking system.

3. Have Your Brake Lines Bled

Apart from getting a brake fluid flush, bleeding of brake lines is also important so as to remove the excess air. When air gets trapped in the brake lines, it compromises the efficiency of the braking system.

4. Replace or Upgrade Brake System Components

From time to time you will need to replace some components of your braking system. This is an opportune time to upgrade to specialized or higher-performance components. Some of the popular brake system upgrades are slotted disc brakes which are more heat resistant and quieter ceramic pads that also emit less brake dust.

5. Brake System Care

There are some external factors that can cause excessive wear to your braking system. Carrying too much weight and heavy breaking are just but some. It’s important that you avoid such situations to preserve your brakes and chances of brake failure.
