Abstract
The present invention comprises a heat shield element (60) having a central opening (62) for receiving the reduced diameter portion (40) of a piston (16) of a disc brake (10). The heat shield element (60) is disposed between a metallic retainer ring/heat shield (50) and the convolutions of a flexible boot seal (30). The retainer ring/heat shield (50) maintains the axial position of the heat shield element (60) and a bead (36) of the boot seal (30), such that the heat shield element (60), which extends radially outwardly of the retainer (50), provides effective shielding of the boot (30).
