6 Common Causes of Brake Failure
Author: Toby Date Posted:22 November 2024
Brake failure is one of the most frightening experiences any driver can face, and it's no surprise that vehicle defects rank among the top causes of road accidents. Fortunately, most brake problems give warning signs before a full failure occurs.
Here are some common causes of brake failure, along with tips to help you spot potential issues before they become dangerous.
1. Worn Brake Pads
Over time, the friction between your brake pads and rotors causes the former to wear out. If they get too thin, they can’t generate enough friction to stop your car effectively. If you hear squealing or grinding noises when you brake, it’s a good sign your brake pads need replacing. Don’t compromise on safety—check out DBA brake pads for reliable performance.
2. Brake Fluid Leaks
A leak in the brake fluid system means there’s less fluid to create pressure, resulting in weaker brakes or even total brake failure. Signs of a brake fluid leak include a soft or spongy brake pedal and fluid puddles under your vehicle. It’s important to regularly check your brake fluid levels to ensure the system is functioning properly.
3. Overheating
Brakes generate a lot of heat due to friction, but under extreme conditions like hard braking or towing heavy loads, they can overheat. Overheated brakes, or brake fade, reduce the braking efficiency and can lead to failure if the system can’t cool down. If your brakes feel less responsive after a long downhill drive or heavy use, give them time to cool before driving again.
4. Faulty Brake Lines
Your brake lines deliver brake fluid to the wheels. If these lines get damaged, pinched, or corroded, the fluid won’t reach the brakes properly, resulting in reduced stopping power. Rust and road debris are common culprits for damaged brake lines. If you notice your car pulling to one side when braking, it could be a sign of a brake line issue that needs immediate attention.
5. ABS System Malfunction
Modern vehicles often come equipped with Anti-lock Braking Systems (ABS) that prevent the wheels from locking up during hard braking. If the ABS malfunctions, your brakes might not engage properly when needed. Warning lights on your dashboard are a key indicator that your ABS needs servicing.
6. Misaligned or Damaged Rotors
The rotors are the discs that the brake pads clamp onto when stopping your car. Warped or damaged rotors can reduce your braking power, cause vibrations, and lead to longer stopping distances. Rotors typically get damaged due to excessive heat or general wear and tear over time.
How to Avoid Brake Failure
Preventing brake failure is mainly about regular maintenance and being aware of early warning signs. Here are a few tips to help avoid brake-related problems:
- Routine Inspections – Regularly inspect your brake system, especially the pads, rotors, and fluid levels. Early detection of worn components or leaks can prevent more serious issues later on.
- Replace Brake Pads on Time – Don't wait for the grinding noise to replace your brake pads. Stay proactive and change them before they wear down too far.
- Check Your Brake Fluid – Brake fluid is often overlooked, but it's essential to check its levels and quality. If it looks dirty or low, it's time for a flush or refill.
- Avoid Overheating Brakes – On long downhill drives or when towing, use engine braking to reduce pressure on your brakes. This will help prevent overheating and brake fade.
- Address Warning Signs Immediately – If you notice any issues—such as vibrations, pulling to one side, or a dashboard warning light—don’t ignore them. Address the problem as soon as possible to avoid further damage.
