Brake caliper assembly having guide pin with non-circular cross-section

Abstract

The invention concerns a guide pin for a brake caliper assembly and a brake caliper assembly for a vehicle disc brake, the vehicle disc brake comprising a brake disc that rotates about a rotation axis, the brake caliper assembly comprising: a brake caliper housing having a receiving section for a brake piston; a brake pad carrier configured to slidingly receive a pair of brake pads; and at least one guide pin configured to guide a relative movement between the brake caliper housing and the brake pad carrier. At least a first section of the guide pin has a cross-section comprising a main axis and a minor axis. A dimension of the cross-section along the main axis is longer than along the minor axis. An angle enclosed by the main axis and a radial direction is smaller compared to an angle enclosed by the minor axis and the radial direction.
