What Are the Most Common Causes of Car Brake Failure Key Factors to Watch For

The brake system of your car is something that is completely associated with the safety controls while driving. Being a car enthusiast, you must know it helps your vehicle to slow down or stop completely as per your wish and circumstances. However, like any auto part, it may rupture over time and behave abnormally, which can not only degrade the overall quality of the ride but also offer you a dangerous driving experience, risking your life from hazardous road crashes. Don’t fret! You are not alone. Here is the breakdown explaining the potential causes behind your car’s failing brake system and the methods to eliminate this issue as soon as possible to get everything back on track.

1. Damaged brake pads

Well, to be honest, the brake pads used to wear each time you push the brake pedal since their work is to produce friction to slow down or stop your vehicle. After carrying out this task consistently, they degrade and start producing unusual sounds like squealing or grinding. Moreover, you may also feel a brake pedal to be spongy due to the pads that have become ultra-thin from rigorous usage. If you continue driving with worn-out pads, it could damage the rotors, leading to expensive repairs down the line. To prevent the rotors from further wear, inspect the pads periodically and replace them before it's too late.

2. Brake fluid leakage

Brake fluid is crucial for optimal brake system operation as it transfers the force to different brake components while pushing the brake pedal. Thus, when the fluid starts seeping out, the brake performance might feel sluggish or may show delayed response, leading to longer stopping distances. If you notice fluid spots or puddles under your car, especially near the wheels, it might be the brake fluid. Address this issue immediately with the help of a trusted mechanic to avoid permanent failure of the brake system.

3. The brakes getting too hot

One of the most common causes behind an overheated brake system is frequent braking, especially on downhill slopes or in heavy traffic streets. This phenomenon is known as "brake fade," and it reduces your ability to stop quickly. In addition, when the brakes become too hot, its pads and rotors struggle to grip. Thus, you could also smell a burning odor or experience a delayed response from the brake pedal. So, you must reduce excessive braking to ensure the system performs at its peak.

4. Air trapped in the brake system

The brake system usually functions through hydraulic force. So, the brake pedal can be spongy or become soft when air gets into the lines. This makes it harder for your vehicle to slow down or stop. But how does the air enter the lines? Well, leaks or improper brake fluid replacement are the potential culprits behind this inconvenience. In this case, you must bleed the brakes to release the trapped air. If braking feels off, it's best to have the brake lines inspected and bled by an expert.

5. Worn-out brake rotors

Your vehicle stops due to the combined action of rotors and brake pads. Thus, you may feel unusual shudders or rough braking even if one of them gets bent or excessively degraded. Overheated rotors often cause warping, particularly after sudden stops or when brake pads are worn out. Moreover, if the steering wheel shakes as you apply the brakes, it might be a warning sign indicating that the rotors need resurfacing or replacing.

The bottom line

With this, you have come to the end of this comprehensive guide. Hopefully, you have grasped a lot of information about the factors that are responsible for triggering the brake system malfunctions. As you have learned, a failing brake system is not something to stand for since ignoring it can be truly dangerous for you as well as your fellow drivers on the road. The best part is most of the brake troubles can be identified at early stages, but only if you pay attention to the minor symptoms like weird noises or a softened brake pedal. Routine maintenance, checkups, and prompt repairs help maintain your brakes and keep you safe while driving.
