<p>A disc brake assembly (12, 14, 112) is provided with heat insulators (26, 126). The heat insulator (26, 126) is disposed between a piston (24) and at least one friction member (22) to prevent heat transfer from the friction member (22) to the piston (24) and the actuating fluid. The heat insulator (26, 126) has a first end (60, 160) with a first end surface (61, 161) received in the recess (50) of the piston (24), a second end (62, 162) with a second end surface (63, 163) and a side wall (64, 164) extending between the first and second end surfaces (61, 63, 161, 163). In one embodiment, the side wall (64) has a protrusion (66) extending from the side wall (64) to space the heat insulator (26) from the piston (50). In an alternative embodiment, the second end (162) has a groove (174) formed in the second end surface (163). <IMAGE></p> |
