The most common culprit of locked-up brakes is a malfunction in the master cylinder. The master cylinder is the primary operating system that produces mechanical force from the brake pedal to pistons that operate the drum brakes. The master cylinder system relies on seals leading to the brakes to maintain pressure so the brake system slides to a stop with ease.Know More
When the seals in the master cylinder break down, the pistons in the system do not return properly, and the line pressure to the brake pads becomes uneven. This chain of events causes the brakes to overheat and lock up. If just one set of brakes locks up, the cause may lie within a caliper piston that is dragging, ultimately causing friction and overheating the brake fluid that then throws off the in-line pressure of that particular brake system.
While replacing the master cylinder is the most expensive repair to fix the brakes, vehicle owners can have a certified mechanic check to see if replacing individual calipers and rotors might provide a solution to brakes locking up before embarking on more major repairs. Routine brake maintenance and brake pad replacement also serves as a preventative measure to reduce the risk of locked-up brakes.Learn more about Brakes
A person can determine if a vehicle has anti-lock brakes by consulting the vehicle's owner's manual to see information about the car's parts and features or by looking for an "ABS" indicator light on the vehicle's instrument panel when the car is first turned on. Anti-lock brakes are more commonly found in newer vehicles. Some benefits of them are that they are less likely to skid and they can be easier to maintain steering with while braking, helping the driver keep control of the car when braking suddenly.Full Answer >
When the brake pads come in contact with the brake rotor to slow and stop a vehicle, the pressure and friction occasionally cause a vibration that produces a squeaking sound. These squeaks are often normal, but they may also mean that the brakes are starting to wear out.Full Answer >
Brake squeal is most commonly caused by one or more of the following: worn brake pads, cheap brake pads, glazed pads and rotors or broken anti-rattle clips. Since there are so many potential causes, it is best to have a mechanic examine the car to determine the cause of the brake squeal.Full Answer >
The common causes of pulsating car brakes can include the Antibrake System (ABS), a poorly installed wheel or a warped rotor. In fact, pulsating car brakes is a common complaint regarding ABS brakes when the ABS system kicks in. This usually happens when braking on ice, wet roads, or gravel.Full Answer >
