MISUSE/THERMAL DAMAGE 2

APPEARANCE

Discs show colouring of varying intensity and shades (blue, violet, golden)

CAUSE

Poor bedding-in. It is normal on new installations to experience slight variations on the surface between the pad and disc. If not properly bedded, the surfaces where friction occurs become overheated leading to a metallurgical change on the friction surface

EFFECT

Poor brake effciency due to decreased friction. Vibrations can occur which may worsen over the life of the pad and disc

SOLUTION

Replace the discs and respect the correct bedding procedure, i.e. moderate use of the brake during the frst 200 kilometres
