The Source of Most Disc Brake Problems

Learn about the problems that can occur with disc brakes, what they do to the safety of the vehicle, and when repairs may be required.

Overheating is the most common cause of issues in every part of the disc brakes. It’s logical since the main purpose of the brake system is to convert energy into heat via friction.

Learn about the many possibilities of problems to diagnose the problem from the road. Ask about the appropriate concerns when the mechanic offers you an estimate, or you can do it yourself.

Disc Brakes: Rotor Problems

Overheating is the leading cause of damage to rotors. While cross-drilled rotors can help disperse heat, they also create the possibility for stress cracks to form due to intense heat. The more likely scenario is that rotors overheated can begin to warp. Rotors that are warped create an elongated sound that could be felt by the brake pedal when it is engaged. Rotors that are damaged by rotors will eventually cause damage to other components in the system.

Disc Brakes: Brake Pad Problems

Intense braking, for example, stopping in an emergency situation due to the speed of a car or continuous braking on an inclined slope, could cause overheating of brake pads, which causes the pads to glaze, essentially turning what was supposed to be a rough surface into an icy one. Glazed brakes lose a lot of the ability they have to grasp the rotors, drastically reducing the braking power. It is advised to replace them as soon as possible.

Disc Brakes: Caliper Problems

For disc brake calipers overheating is often caused by the issue. A piston that is seized in the caliper results in the brakes failing to engage or disengage. The first causes a reduction in braking power in the wheel. The second causes the brake pads to be active, causing the vehicle to move toward one side, overheat the brake rotors as well as the pads, and, in the end, start to smoke. If you experience any of these signs, then pull over. A tow to the mechanic, or DIYers who are able at home, a repair is the best option in this case.

Disc Brakes: Brake Fluid Problems

Overheated pads and rotors can transmit excessive heat through the piston of the caliper to brake fluid leading the fluid to become boiling. In this case, it loses the fluid’s capacity to compress and reduces braking effectiveness. This is a very risky situation, and you shouldn’t drive your vehicle until repairs can be made, and not even until you can get it back to your home.
