ROTOR FOR A DISC BRAKE ASSEMBLY

摘要

A rotor for a disc brake assembly is provided with a first portion (52) adapted for attachment to a wheel assembly (28), a second portion (54) engageable with at least a pair of friction elements and a connecting portion (56) extending between the first and second portions. The second portion (54) defines an inboard surface (60) and an outboard surface (64) facing the first portion (52). The connecting portion (56) cooperates with the second portion (54) to define a heat sink (78) at the radially inner edge of the inboard surface (60) to substantially offset tilting of the second portion toward the first portion in response to temperature expansion of the rotor second portion (54).
