Common Braking System Problems

04/Oct/2023 129 |

It’s important to recognize the signs of brake problems and to know what to do if they occur. The ability to stop is more important than the ability to go. here are some of the more common brake problems.

NOISY BRAKES

The brakes should not make any noise when operating. If they squeal or make a metal-on-metal grinding sound, the brake pads are probably worn and need to be replaced. 

VIBRATION

You may notice the car shuddering as you apply the brakes and the shuddering slowing as the car slows down. This vibration is usually caused by a crack in the rotors, uneven wearing of the pads or shoes, or the transfer of friction material onto the rotor surface. If you find a crack in either the metal or ceramic coating of the rotor or drum, the rotor or drum will need to be changed. Replace unevenly worn brake pads, and have the rotor turned (resurfaced) to even out the surface. 

PULLING TO ONE SIDE

If you notice the car pulling to one side when you apply the brakes, it is likely due to contamination in the brake components, or a faulty caliper or brake cylinder. It can also happen if you have differently-sized tires, such as when you’re driving on a temporary spare. Worn suspension parts can also cause this problem.

SOFT OR SPONGY BRAKES

You may begin to notice over time that you have to push harder on the brake pedal to engage the brakes and bring the car to a stop. If the brakes are still working, the usual suspects include low fluid level, worn pads, worn out or dirty fluid, or a failed booster. As disc brakes wear, they don’t retract like drum brakes, so the level of fluid decreases. If you go too long without adding more fluid or changing the fluid, they can give you excessive brake pedal travel. If the brake pedal goes to the floor but you have little or no braking action, the brakes have lost the ability to produce pressure. This can be caused by a leak in the lines or brakes or a failure of the master cylinder or distribution block.

Inspect the Brakes

You should check your brakes or have them inspected about every 10,000 miles or 15,000 kilometers.
