Listen…
Have you ever heard a high-pitched screeching sound when you applied your brakes? That’s a small metal shim, called an indicator, which is giving you an audible warning that you need to replace your brake pads.
Reduced responsiveness or fading
If your brakes are not as responsive as they should be or if the pedal “sinks” toward the floor, this could be an indication of a leak in the braking system. It could be an air leak (in the brake hose) or a brake fluid leak. One telltale sign of a brake fluid leak is the presence of a small puddle of fluid when the car is parked. Brake fluid looks similar to fresh motor oil, but with a less “slimy” texture.
Pulling
If your vehicle “pulls” to one side while braking, it may be a sign that the brake linings are wearing unevenly or that there is foreign matter in the brake fluid. Your vehicle may need a brake adjustment or to have the fluid drained and replaced.
Grinding or growling
This loud metallic sound means that you have worn down the pads completely, most likely beyond replacement. The grinding or growling noise is caused by the two pieces of metal (the disc and the caliper) rubbing together. This can “score,” or scratch your rotors, creating an uneven surface. If this happens, do not be surprised if your mechanic tells you that the rotors need to be “turned” (a process that evens out the rotor surface), or even replaced.
Vibration
A vibration or pulsating brake pedal is often a symptom of warped rotors (but can also indicate that your vehicle is out of alignment). The vibration can feel similar to the feedback in the brake pedal during a panic stop in a vehicle equipped with anti-lock brakes.
