Disc brake caliper.

摘要

The calliper is for a disc brake having a bracket (1,2,4) straddling the disc (D) and floats in the bracket at right angles to the disc. The calliper comprises a hydraulic cylinder (13) with piston working in a direction parallel to the direction of calliper movement. Brake shoes (5,8) acting against opposite sides of the disc are secured one to the piston (16) and one to the part of the calliper (12) opposite the cylinder. The bracket has a support (17) with cylindrical guide (18) at right angles to the disc and passing through the thrust centre of the shoes. The piston has a coaxial tappet (20) sliding along the guide and coupled to one shoe (5). The calliper position on the bracket is stabilised by spring components acting between them.
