Brake Repair: Most Common Repair

The most common type of brake repair lies within the hydraulics of the system. Brake fluid is vital to the brakes because it transfers force into pressure, which helps the other components of the braking system work correctly. The force needed to stop the car is far greater than the force applied when the operator of the vehicle presses their foot on the brake pedal. The fluid provides the hydraulic force needed to efficiently operate the brakes with the force needed. Often times, it needs to be flushed out of the car, and replaced because old fluid has a lower boiling point, and tends to attract moisture.

The excess moisture can cause rust, and is especially damaging to anti-lock braking systems. Mechanics recommend a flush every 30,000 miles, it is good preventative maintenance toward keeping the system working efficiently. Bleeding is simply letting some of the fluid out to remove the air pockets that have become trapped in the system. Checking the brake fluid can provide details of any required maintenance from refilling, to leaks.

Another common brake repair is replacing the brake pads. The pads lie within the disc and provide a buffer between the calipers and the rotors. When the brakes are applied, the caliper squeezes the pads into the rotor, which stops the vehicle. Although there isn't a specific mileage milestone to indicate a need for new pads, the pads are equipped with a small metal tab that will rub against the rotor and make a squealing noise when they have worn thin and need replacement. Ignoring this warning signal for too long can lessen braking efficiency and cause serious damage to the rotors.

The master cylinder controls the volume of fluid that is forced through the system. When the master cylinder malfunctions, there is an internal leak that is not always immediately detected by brake fluid leaking from the car. Attention should be given to this component if the pedal slowly sinks to the floor when the pedal is applied, or if the operator must 'pump' the brakes in order for the pedal to return to normal pressure. A red warning light will also appear on the dashboard if there is a problem with the master cylinder. If leaking is more obvious, the problem my be with the tubes or hoses that carry the fluid from the master cylinder.

The braking system has many components working together that enable safe operation of a vehicle. Always pay attention to how the brakes feel when pressure is applied, and take the car to a certified mechanic for preventative maintenance. Never put off repairs to the braking system.
