Brake Pad Problems

Brake pads are a very important element of a vehicle's braking system. Although relatively cheap and easy to install, brake pads provide the main braking action of a vehicle's braking system. When brake pads develop problems, they can jeopardize the efficiency and functionality of the entire braking system. What follows is a list of the most common brake pad problems.

Brake Dust

All brake pads, regardless of the type, produce brake dust when the breaks are applied. Although a normal part of brake pad wear and tear, brake dust, especially in large amounts, can disrupt normal braking function, cause brake noise, and make wheels and tires dirty.

Vibration

While it is common for most brakes to exhibit small amounts of movement and/or vibration when the brakes are applied, excessive amounts of brake pad vibration can limit brake pad gripping power and also cause excessive brake noise.

Cracking

Although brake pads wear and become thinner over time, brake pads, especially pads that are defective and/or of low quality, can develop cracks in their surfaces, which can lead to brake pad breakage and/or failure.

Glazing

Brake pad glazing occurs when brake pads lose their roughened, porous outer covering and instead develop a smooth, polished covering. This type of brake pad condition reduces overall stopping ability by reducing the amount of friction that the brake pads can apply to the spinning brake rotor.

Overheating

When brake pads overheat, they can become soft and spongy, a condition that makes them more susceptible to breaking and/or flaking, and reduces braking power. Although most brake pads are made to withstand severe temperatures, many cheaper-quality brake pads are prone to overheating.
