Maintaining a vehicle is more than just a way to protect one’s financial investment. Vehicle maintenance can protect against accidents and make the road safer for drivers and their passengers as well as their fellow motorists.

Fully functioning brakes are an important component of automotive safety. In its 2015 Crash Stats report, the National Highway Traffic Safety Administration said that brake-related problems accounted for 22 percent of crashes where vehicular failure was cited as the cause of the collision. Bad brakes are particularly notorious for rear-end collisions. Faulty, worn brake lines, antilock brake system malfunctions and worn brake pads and discs are some potential brake problems.

It is important that motorists learn to recognize the first symptoms of brake trouble so they can address issues before they put drivers, their passengers and other motorists at risk of accident or injury.

• Unusual noises: Screeching, grinding, rubbing, and high-pitched sounds are common indicators that brake pads, rotors and other parts of the braking system need attention. Worn pads can cause damage to other vehicle parts, resulting in more expensive repairs if they’re not addressed promptly.

• Pulling: If the car pulls to one side when applying the brakes, this may indicate brake pad linings are wearing down unevenly. A brake adjustment may be necessary. Pulling also may be indicative of an object or debris caught in the brake fluid.

• Less responsive: If when pressing on the brake pedal the brakes just do not seem to be as effective as they once were, or it is necessary to press the pedal harder for the brakes to engage, there may be a brake fluid leak or an air leak. Check under the vehicle to see if any fluids are pooling.

• Pungent odors: Firestone Tire Company says a burning smell may be indicative of worn out brake pads and friction on the tires. Each of these issues require immediate attention.

• Vibrations: Certain vibrations may indicate brake issues. Rotors can become warped from metal-on-metal rubbing, potentially leading to a failure of the vehicle to brake properly. Vibrations also may indicate tires are misaligned. These problems can be properly assessed by a trained mechanic.

Do not let potential brake problems go unchecked. Keeping brakes in good working order helps drivers stop more readily and avoid collisions.
