Scope

This document describes two methods for measuring the thermal expansion of disc
brake pads: the heating plate method and the oven method to determine the dimensional
change as a function of temperature, as well as its heat conduction.
Dimensions include:
-- thickness;
-- certain profile dimensions of a disc brake pad whose variations may cause brake
failure.
This document applies to molded or bonded disc brake pads with a solid backplate and
with a width not greater than 120 mm, a height not greater than 80 mm, and a thickness
not greater than 20 mm.
