Abstract
A vehicle brake assembly including a brake caliper defining a caliper housing and defining a plane of rotation of a brake disc, the housing having an opening facing the plane of rotation of a brake disc, a cover plate for closing the opening and an actuator assembly at least partially mounted in the housing, wherein the actuator assembly includes at least one piston for moving a friction element into contact with a brake disc, an adjuster mechanism for adjusting the effective length of the at least one piston, the adjuster mechanism including an adjuster shaft, the adjuster shaft being fixed to the cover plate by a spring clip arrangement.
Claims11
A vehicle brake assembly comprising:
- a brake caliper defining a caliper housing and defining a plane of rotation of a brake disc, the caliper housing having an opening facing the plane of rotation;
- a cover plate for closing the opening;
- an actuator assembly at least partially mounted in the caliper housing, wherein the actuator assembly includes at least one piston for moving a friction element;
- and
- an adjuster mechanism for adjusting an effective length of the at least one piston, the adjuster mechanism including an adjuster shaft, the adjuster shaft being fixed to the cover plate by a clip arrangement.
A method of assembling a vehicle brake assembly comprising:
- providing a brake caliper defining a caliper housing and defining a plane of rotation for a brake disc, the caliper housing having an opening facing the plane of rotation;
- providing a cover plate for closing the opening;
- providing at least one piston for moving a friction element that is adapted to contact the brake disc;
- providing an adjuster mechanism for adjusting an effective length of the at least one piston, the adjuster mechanism including an adjuster shaft;
- providing a clip arrangement;
- providing a bias device;
- providing a subassembly by fixing the adjuster mechanism to the cover plate via the clip arrangement such that the bias device biases the adjuster shaft away from the cover plate and the adjuster shaft is prevented from moving away from the cover plate by the clip arrangement and attaching the at least one piston to the cover plate, the at least one piston and the adjuster mechanism at least partially defining an actuator arrangement, the subassembly being provided remotely from the caliper housing;
- and
- subsequently assembling the subassembly to the caliper housing such that the actuator arrangement is at least partially mounted in the caliper housing and the opening is closed by the cover plate and the cover plate is secured to the caliper housing.
