Abstract

The invention is particularly concerned with a caliper for a disc brake assembly. The caliper includes a cylinder and a bridge, the bridge having an inboard portion which attaches to the cylinder, a central portion, and an outboard portion. Inboard and outboard friction pad assemblies are arranged to be brought into contact with opposite faces of the disc. The bridge is formed of a resiliently flexible material and is shaped and configured such that under braking conditions the outboard portion is able to resiliently deflect relative to the inboard portion in a direction transverse to the axis of the cylinder and substantially parallel to the direction of movement of the disc at the region where the friction pad assemblies are in engagement with the faces of the disc. The bridge and cylinder may be separately formed and connected together or they may be integrally formed.

Dependent claims

A disc brake assembly engageable with a disc rotatably mounted on a vehicle, comprising,

an anchor bracket adapted to be mounted in fixed relation on a motor vehicle,
a caliper comprising a bridge and a cylinder, said bridge having an inboard portion and an outboard portion on opposite sides of the disc, said inboard and outboard portions being connected by a central portion,
said cylinder mounted to said inboard portion,
a piston slidably mounted in said cylinder,
inboard and outboard friction pad assemblies having planar faces adapted to be brought into frictional contact with opposite faces of the disc,
the rigidity of the central portion being such that the outboard portion of said caliper is resiliently deflectable relative to said inboard portion in a direction transverse to the axis of said cylinder and parallel to the direction of movement of said disc at the region where said friction pad assemblies are adapted to engage said disc, the rigidity of the caliper in a plane perpendicular to said deflectable direction being sufficient to substantially prevent said pads moving out of parallel with each other under braking conditions.
