Identifying Some Common Causes of Brake Failure

Last updated 3 years ago

Automotive brakes require friction to bring the car to a stop. But a number of things can interfere with the braking system’s ability to generate friction. To take a closer look at how brake failure occurs and how you can prevent it by going to a reputable automotive repair shop, read on.

Greasy or Oily Brakes

One of the most common causes of brake failure is exposure to oil or grease. If an oil seal fails and begins to leak oil on the components of your braking system, get the leak fixed and the braking system cleaned as soon as possible.  

Extreme Heat

Overusing the brakes by riding them or making frequent panic stops, especially when traveling at high speeds or down a sharp incline, will cause the brakes to overheat. When the brakes overheat, the brake rotors or drums develop hard spots, also known as hot spots, which interfere with the proper functioning of the shoes and pads, effectively reducing braking power.

Worn Brake Pads

Do you hear a high-pitched whine when you apply the brakes? This usually means the brake pads have become worn out, and need to be replaced at an automotive repair shop right away. Failure to replace worn brake pads can result in damage to the rotors, which is characterized by a grinding sound during braking.

Low or Dirty Brake Fluid

Automotive repair specialists recommend changing the brake fluid every 48,000 miles or every 4 years. When the brake fluid becomes dirty or starts to leak, the brakes will lose effectiveness and eventually fail.

If your vehicle is exhibiting some of the common symptoms of brake trouble—unusual noises or vibrations during braking, or pulling to one side during braking—come to Dekalb Tire for brake maintenance as soon as possible.
