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.
