Nej ! Det opstår som resultat af overophedning :
"When a friction compound is used in a substantially higher
temperature range than intended, the material can quickly lose its
ability to perform correctly. Continued use under these circumstances
may result in complete brake failure. This occurs when certain
ingredients in the friction compound break down and cause glazing of
the rubbing surface of the brake pad. "
"Pad fade can be caused by several factors. All friction materials
have a coefficient of friction curve relating to temperature. Friction
materials are designed to work at an optimum temperature when the
coefficient of friction is the highest. When brakes are used too
frequently,if the pad material is not adequate for the temperature,
then the coefficient of friction can decrease. Brake materials are
different, and with enough temperature the material can melt and
cause the coefficient of friction to rapidly decrease to the point
where the material will melt and/or change its frictional
characteristics and cause a lubrication effect.
As temperature increases, the friction material can melt and the
resins that bind the friction material can vaporize and “out-gas”.
These vaporized gases prevent intimate contact with the
rotor which, in turn, reduces friction. Some pad materials change
slowly at elevated temperatures while other materials react with a
sudden and dangerous loss of friction. The result is “glazed”
brake pads and rotors."
