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.
