- Oil or grease on your brakes can lead to failure. Unlike your engine, the brakes do not need lubrication, and if lubrication such as oil or grease make its way to the brakes, this interferes with the friction needed to come to a stop. Keep an eye out for oil leaks. If you notice a leak, this can indicate that an oil seal has failed. Get this checked immediately to prevent further damage.
- Your brake pads are built to work up to a certain temperature. If your brakes get severely overheated, they start to break down. If this happens, the metal in the rotors or drums can develop hard spots, also known as hot spots. These spots interfere by resisting the friction from the brake pads and shoes. If these don’t have friction, braking power is lost. A symptom to look for here is a change in feel on your brake pedal. If you notice that you’re having to press harder on the pedal, and seeing less of a reaction, get this checked immediately.
Common Reasons for Brake FailureJuly 21, 2017
One of the scariest situations a driver can experience is their brakes suddenly failing. Before you get into a panic about this scenario, let’s understand how your brakes work, and then unpack causes that can lead to their failure. The brake pedal is connected to the pistons. In most modern cars, you’ll see disc front brakes and drum rear brakes. Functioning brakes stop your vehicle by using friction. If something interferes with this friction, this can lead to brake failure. Here are a couple factors that can become an interference:
