Abstract
The vehicle brake with brake cylinder bore insert (30, 130) comprises a cast disc brake cylinder (12, 112) which includes a bore (14, 114) into which the bore insert (30, 130) may be disposed. The bore (14, 114) may have an opening (22, 118) at either one (20, 120) of the opposite axial ends for inserting the bore insert (30, 130). The insert has lock ribs (34) disposed about the perimeter (32) thereof, and at opposite axial ends a pair of perimeter extensions or crush ribs (36) which tightly engage the surface (21, 121) of the bore (14, 114) when the insert (30, 130) is disposed within the bore (14, 114). The insert (30, 130) has opposite flat sides (50) which permit an adhesive material to be disposed between the lock ribs (34) and the surface (21, 121) of the bore (14) in order to fix the insert (30) within the bore (14). The insert (30, 130) contains a central opening (39, 139) which may be of different diameters or shapes for receiving a piston (40) and seals disposed about the piston (40).
