BRAKE FAILURE IN CARS - POSSIBLE CAUSES

CHECK

1.  Brake Caliper ...... Brake Caliper Piston Sticking Causing Brake Drag

2.  Brake Release Handle Cable ..... Parking Brake  Cable Seized.

3.  Brake Power Booster ... Incorrectly Installed Brake Power Booster.

4.  Stoplight Switch ..... Misadjusted Stoplight Switch.

5.  Brake Rotor  ...... Warped or Uneven Brake Rotor Surface.

6.  Brake Pad/Shoe Rear ... Brakes Installed or Adjusted Incorrectly.

Excessive pedal travel, whether soft or hard pedal, can be an indicator that serious problem may have developed in the brake system. It could a leak in the hydraulic system or brake shoes/pads have worn-out unevenly.

Fluid leakage may be as a result of wear in the master cylinder parts. Usually, when the brake is marched, the fluid is forced to flow from the cylinder to each of the wheels. Any little fracture or hole in the system can force the fluid to leak away leading to loss of pressure necessary to press the pedals to the wheel drum.

The wheel cylinder is also the source of many brake problems. If brake fluid leaks from the wheel cylinder, the vehicle could experience unreliable stopping, damage to new brake shoes, or partial brake system failure. A sticking wheel cylinder may cause brake drag, excessive pedal effort, and reduced braking efficiency.

Another cause of brake failure in vehicles could be as a result of malfunctioning wheel drums of the rear wheels. Worn drums and shoes can cause unreliable stopping, excessive pedal effort, or brake pedal pulsation.

. Disc Brake Assembly When the brake pedal is pushed, brake fluid from the master cylinder compresses the brake pads against the rotors attached to the vehicle's front wheels. The friction between the stationary pads and the revolving rotors causes the rotors and wheel to slow and stop. As car is driven during the day, these rotors and pads are subject to much abuse, and should be checked periodically for wear. Faulty disc brakes can cause excessive pedal travel, pumping or fighting pedal, vibration during braking action, and brake failure.
