Common Reasons for Brake Failure

Brake failure is a serious issue that can lead to accidents and injuries. Here are some of the most common reasons for brake failure:

  1. Loss of Brake Fluid: Brake fluid is essential for the proper functioning of the braking system. If there is a leak in the brake lines, the brake fluid will slowly drain out, and there won’t be enough left to transmit the pressure from the pedal to the tires. Loss of brake fluid is one of the most common causes of brake failure12.
  2. Worn-out Brake Pads or Shoes: Brake pads and shoes create the friction that is used to slow down and stop the wheels. Over time, they can become worn out or damaged, and if they wear down too far, the performance of the braking system can become severely compromised. Worn-out brake pads or shoes are a common cause of brake failure3.
  3. Overheating: Brakes can overheat due to excessive use, such as driving down a steep hill. Overheating can cause the brake pads to become hard or brittle, decreasing their ability to properly grip the wheel rotor disk and increasing the distance required to stop the vehicle4.
  4. Contamination: Grease or oil on brakes can cause brake failure because it interferes with friction. If oil leaks, it may indicate that an oil seal has failed. Contamination is a less common cause of brake failure2.
  5. Poor Maintenance: Brakes, like many other parts of an automobile, have a limited lifespan and should be occasionally inspected for wear. Neglecting to maintain your brakes can lead to brake failure56.

If you experience brake failure while driving, it’s important to stay calm and take immediate action to stop the vehicle safely. Pump the brake pedal continuously to build residual pressure in the brake system and slow the car. If you feel brake pressure return, gradually press the brakes until you come to a stop. Use your horn to warn other drivers, downshift to a lower gear, and use your emergency brake if necessary78.

To prevent brake failure, it’s important to have your brakes inspected regularly, replace worn pads, rotors, brake fluid, and hoses, and avoid sudden stops, hard braking, and excessive speed. Following these tips and tricks will help you keep your brakes in top condition and prevent brake failure96.

Now, let’s dive into the step-by-step process to fix your bike brakes and ensure they function flawlessly.
