ABSTRACT:
The spacer (50) comprises a generally C-shaped member which is disposed about a complementary shaped pin (40) which connects a caliper housing (12) to a torque support member (16) of a disc brake (10). The pin (40) has radially opposite flat side portions (42, 44) connected by curved surfaces (46, 48). The spacer (50) includes a pair of oppositely disposed and axially spaced apart upper flanges (58) at opposite ends of a bowed upper portion (54), and axially spaced apart lower flanges (60) which are bent axially inwardly toward one another. Each of the lower flanges (60) has a corner ear (62) adjacent a curved portion (52) of the spacer (50) which are bent outwardly away from one another. Adjacent the ears (62) where the lower flanges (60) engage the curved portion (52) are axially opposite notches (64) which prevent stress cracking of the spacer (50).
