The drum above shows the tell tale
signs of "heat checking" caused by sustained high temperatures. |
Brakes work by converting kinetic energy into heat
energy so brakes are going to get hot. But when brakes get too hot bad
things can happen. The most dangerous thing about hot brakes is a
decrease in braking power known as brake fade. To see how dramatically
hot brakes can increase stopping distance click here.
Heat increases brake wear...
High heat also substantially increases brake
wear. According to a study by a major brake manufacturer for every
increase of a 100 degrees over the normal operating temperature brake wear
doubles. The longer brakes stay at high temperatures the more wear
they experience.
Heat causes brake fade...
BrakeTurbines work to reduce heat by blowing a
steady stream of air in between the drum and the friction material.
This air helps dissipate the heat from the surface of the drum and shoes to
reduce wear and lower incidences of brake fade.
