6 Brake Problems to Beware Of

No matter how you drive, brake problems can surface and put you and your family at risk. When you develop a brake problem be cautious and call for service. Do not drive the vehicle to another location unless you are stuck in an intersection. The following is a list of the 6 most prominent brake problems:

ABS Brake Warning Light Appears

The ABS warning light means that your car's onboard computer has shut off the ABS braking system. The computer will shut it off when it has picked up on a problem. Your car's brakes will stop you, but you will have no protection against a brake or wheel lock-up. You will be able to get to an auto repair center safely.

Brake Warning Light Appears

This can simply advise you that the car's emergency brake is still engaged. Release it if it is on, and see if the light goes out. More seriously, your brake lubricating and cooling fluid may be low. Take the vehicle and have the fluid checked and filled.

If refilling the brake fluid does not turn the light off, you may have a fluid leak in one part of the braking system. If you are at the auto service center, alert them to check the entire brake system.

Locked Brakes

If your vehicle has ABS, but you still lock up your brakes when applying them, a dangerous problem exists. It could be due to a damaged brake pad, shoe or both, or it could be related to the disc calipers or wheel bearings. Call for roadside assistance and get tow truck right away.

Brake Pedal Won't Go Down at All, "Hard" Brake

This problem has causes ranging from simple: something stuck under the brake pedal; to complex: pinched or failed brake fluid line, or a failure of the power brake boosting mechanism, among others. Check under the brake pedal for a blockage, often just a crumpled floor mat. If this does not solve the problem, contact roadside assistance for a tow to an auto repair center.

Brake Pedal is "Mushy", Goes Down Well Beyond Normal Level

Mushy or spongy brakes can result from air in the brake fluid line. Also, there may be a more serious problem, brake fluid leak or damage to the master brake cylinder. Call for a tow truck and bring in your car to a service center.

Brakes Squeal

The squealing noise made by brakes has many sources. It could be dirt trapped in the wheel. Run the vehicle through the car wash to see if it can be cleaned out. An intermittent brake squeal that sounds only when brakes are on can be from worn brake linings, worn, warped or cracked brake shoes or brake adjusters that need realignment. A continuous brake squeal, even when they are not applied, indicates either wheel bearing damage or that your brake pads have reached the replacement point. Have this repair done soon to prevent brake rotor damage.

Your brakes are your car's key safety system. Have them inspected and maintained regularly.
