What is the permanent condition caused by the brakes overheating on numerous occasions?

• A. Brake Glaze
• B. Brake Fade
• C. Warped Rotors
• D. Brake Chatter

Answer: (A)

When brakes overheat repeatedly, the friction material on the pads can become glazed. This creates a hard, smooth, glassy layer on the pad surface that dramatically reduces friction during braking. Because this glaze sticks to the pad and doesn’t disappear with cooling, it becomes a permanent-type condition until the pads (and often the rotors) are replaced or resurfaced. This is different from brake fade, which is a temporary loss of braking power during a heavy stop, and from rotor warping, which is a physical deformation of the disk. The glaze caused by repeated overheating best fits the idea of a lasting surface condition resulting from heat.
