Beware! Brakes Failing: How Common is It?

Brake failure is a serious concern for drivers, but thankfully, it is uncommon. In general, brake failure occurs only in extreme cases where regular maintenance has been neglected or initial brake system defects have gone unnoticed.

Brakes are one of the most critical components of a vehicle’s safety systems. As such, their failure can cause catastrophic consequences. Despite this, brake failures in modern vehicles are rare. Most modern vehicles have advanced braking technology, including anti-lock brakes, traction control, and electronic stability control, which make it more difficult for brakes to fail.

However, brake failures can occur in some cases. This can happen due to a lack of maintenance, such as worn-out brake pads or a leaking brake line. Additionally, design and manufacturing defects are also possible factors leading to brake failure.

Beware! Brakes Failing: How Common is It?


Causes Of Brake Failure

Brake failure is a terrifying situation that no driver ever wants to face. It’s essential to understand the causes of brake failure to ensure your safety and that of others on the road. Here are some common causes of brake failure:

Wear And Tear Of Brake Components

The constant use of your brakes leads to gradual wear and tear of various brake components, including the brake pads, rotors, and calipers. Over time, these components weaken and eventually fail, leading to brake system failure. Squeaking noises and reduced stopping power of the brakes are the usual symptoms of wear and tear.

Adequate maintenance and replacement of damaged components can help avoid brake failure.

Overheating Of Brake Components

Overworking the brake system can cause brake components to overheat, leading to reduced stopping power and eventual brake failure. Hard braking or driving in hilly areas without giving the brake system some rest in between can cause overheating of brake components.

Regular rest periods and avoiding overworking the brake system can help prevent overheating.

Contamination Of Brake Fluid

Brake fluid contamination can occur when moisture or air enters the brake system, leading to brake failure. Moisture can cause rusting of brake components, resulting in damage that negatively affects brake performance. Regular replacement of brake fluid can help avoid moisture build-up and rusting.

Malfunctioning Of The Brake Master Cylinder

The brake master cylinder is responsible for converting the force applied on the brake pedal to hydraulic pressure, which activates the brakes. Malfunctioning of the brake master cylinder can cause brake failure, leading to accidents. Regular inspections and replacement of damaged brake master cylinders can help prevent brake failure.

Natural Wear And Tear Of The Brake Pads

Brake pads wear out naturally with constant use, resulting in reduced stopping power and eventual brake failure. Worn-out brake pads can scrape against brake rotors, producing screeching noises, and damaging other brake components. Regular maintenance and replacement of brake pads can help prevent this kind of brake failure.

Inadequate Brake Maintenance

Inadequate brake maintenance is a leading cause of brake failure. Skipping routine check-ups and inspections can cause brake components to wear out and eventually fail. Regular maintenance and inspections can help identify any problems and address them before they cause brake failure.

Stuck Brake Components

Stuck brake components, such as brake calipers, can cause the brake system to overheat, leading to accelerated wear of brake components. It’s essential to identify and replace stuck brake components to avoid brake failure.

Understanding the causes of brake failure is crucial in avoiding accidents. Regular maintenance, inspections, and replacing damaged components can help prevent brake failure and ensure your safety and that of others on the road.

Signs Of Brake Failure

Your vehicle’s ability to stop is dependent on the functioning of the braking system. Unfortunately, it’s impossible to tell if your brakes are working correctly just by looking at them. Knowing the signs of brake failure is crucial for spotting potential issues before they turn into something more dangerous, such as an accident.

Below are the most common signals that indicate brake failure:

Unusual Noises From The Brake System

If you hear any strange noises from your brakes, it could be a red flag. Grinding, screeching, or squeaking sounds are the most noticeable. These noises usually indicate the brake pads need replacing, but if the noise is persistent, it may indicate something more serious is happening with the brake system.

Difficulty In Applying Brakes

A brake pedal that is difficult to press, or feels spongy, can be a sign of air in your vehicle’s brake lines. An unresponsive brake pedal is dangerous, and drivers need to contact a mechanic and avoid driving until the issue is rectified.

Spongy Brake Pedal

A spongy brake pedal is indicative of a hydraulic system problem or a possible brake fluid leak. If your brake pedal feels like it goes down too far, it may be time to have your brake system checked.

Vibrations While Braking

If you are feeling unusual vibrations while braking, it could be an indication that your brake rotors are warped. Warped rotors can happen over time with normal use, or often occur after sudden high-braking scenarios. It can also indicate a problem with the brake caliper or suspension.

Braking Imbalance Between Wheels

It’s important to keep in mind that each wheel in your vehicle’s brake system should work in sync with the other. If you notice that one wheel is slowing more quickly than the other, it’s a symptom of brake failure.

Brake Warning Light On Dashboard

Almost every modern vehicle is equipped with a brake warning light on the dashboard. If it lights up, it indicates that there is an issue with the brake system. It could mean anything from worn brake pads to a major hydraulic system failure.

Ignoring signs of brake failure can have serious consequences. Drivers must keep their brakes operating smoothly by getting regular maintenance checks and repairs by qualified technicians.

Preventive Measures And Maintenance Tips

Regular Maintenance Of Braking System

To avoid brakes from failing, regular maintenance of your braking system is essential. This ensures that all components are properly functioning. Here are some key points to consider:

  • Check your brake system every 12,000 miles or every 12 months.
