Brake Repair and Brake Systems Information

In order to quickly stop the momentum of the average 4,000 pound car, the braking system uses a network of hydraulics, levers, and springs to transfer the right amount of energy that will stop the vehicle's wheels. Replacing the brake pads is a common brake repair issue. Brake pads are situated between the calipers and the rotors. When the brakes are applied, the caliper applies the pads to the rotor, which slows the vehicle's momentum. Although there isn't a specific mileage milestone for replacing the brake pads, they are equipped with a small metal indicator tab that will rub against the rotor and create a squealing noise when they have worn thin. If the pads are not replaced within a reasonable amount of time, the rotors will become damaged from constant metal contact; and although the cost to replace the pads is fairly inexpensive, replacing the rotors can be much more costly.

The amount of energy needed to stop the vehicle is far greater than the force applied when the brake pedal is depressed. Hydraulics are used in the braking system to transfer the force from the driver's foot on the pedal through to the wheels to actually stop the car. Often times, the hydraulic fluid will need to be replaced because old fluid tends to attract moisture, which can cause rust and corrosion. Bleeding the fluid can remove air pockets in the system that can affect the amount of force needed to slow the vehicle's momentum.

An anti-lock braking system (ABS) is an added feature to the brake system that prevents skidding in the event of a sudden stop, or slippery road conditions. When the brakes are applied in these situations, the wheels tend to lose traction, which causes the wheels to spin, unless the vehicle operator pumps the brake pedal. The ABS automatically pumps the brakes to prevent the wheels from locking, giving the driver added traction and safety. Along with the other components of the braking system, the ABS also uses a network of wires and computer sensors to operate properly and repairs to this system will require advanced skill and tools.

Brake repair can be expensive, but it is necessary for safe operation of any car. There are common repairs, which can be performed without a mechanic's skill. However, do-it-yourself projects on brake repairs may not be efficient for novice auto mechanics. Many times, it may be difficult to diagnose the brake repair issue, and a skilled technician can accurately and confidently service the car for safe operation.
