In a disc brake assembly, the combination of, a torque member disposed adjacent a rotor to be braked, a pair of pin assemblies extending from the torque member in a direction opposite the rotor, a caliper slidable on said pin assemblies and cooperating with a pair of friction elements to urge the latter into engagement with the rotor, each of said pair of pin assemblies including a sleeve defining an opening, a bolt extending through said opening to engage said torque member, and a pair of washers, said bolts being secured to said torque member in order to retain said sleeves fixedly disposed relative to said torque member, said washers of one pin assembly engageable respectively with opposite ends of said sleeve of said one pin assembly and cooperating therewith to substantially prevent lateral movement of said sleeve of said one pin assembly relative to said bolt of said one pin assembly, said washers of the other pin assembly engageable respectively with opposite ends of said sleeve of said other pin assembly and cooperating therewith to permit angular orientation of said sleeve of said other pin assembly relative to said bolt of said other pin assembly, said washers of said other pin assembly also permitting lateral movement of said sleeve of said other pin assembly relative to said bolt of said other pin assembly, said washers of said other pin assembly defining openings therethrough substantially equal in diameter to said opening in said sleeve of said other pin assembly to form a large clearance with said bolt of said other pin assembly, said washers of said one pin assembly defining openings therethrough substantially equal in diameter to said bolt of said one pin assembly to form a close fit therewith, said washers of said one pin assembly being formed with conically tapered surfaces and said opposite ends of said sleeve of said one pin assembly being tapered to receive said tapered surfaces of said washers of said one pin assembly therein to thereby prevent said lateral movement, said washers of said other pin assembly being formed with arcuate surfaces and said opposite ends of said sleeve of said other pin assembly having corresponding arcuate surfaces engageable with said arcuate surfaces of said washers of said other pin assembly to thereby permit said angular orientation and lateral movement.
