Abstract: A disc brake system of the kind comprising an axially fixed hub and at least one slideable brake disc comprises a resilient device acting between the disc and the hub to control certain aspects of the movement of the brake disc during use. Despite the thermal differential arising in use between the brake disc and the central hub due to the localized heat generation of the brake system and the mass and thermal capacity differences between the hub and the brake disc, whereby the hub would be expected to provide a more satisfactory mounting, the resilient device acting between the disc and the hub to control the disc dynamics is mounted on the disc.

Abstract: A spot-type automotive disc brake of floating-twin disc and fixed-caliper format utilizes one or more single wire springs to bias the two floating friction elements with respect to the fixed caliper. Each spring exerts a differential resilient effect on the central friction element with respect to the floating side friction element by virtue of differential connection arrangements, thereby meeting the differential springing requirements.

Despite the thermal differential arising in use between the brake disc and the central hub due to the localized heat generation of the brake system and the mass and thermal capacity differences between the hub and the brake disc, whereby the hub would be expected to provide a more satisfactory mounting, the resilient device acting between the disc and the hub to control the disc dynamics is mounted on the disc. Such provides independence of the resilient bias with respect to disc position and disc relationship to another disc and with respect to simplicity of mounting and avoidance of dirt entrapment.

Abstract: Spot-type automotive disc brake (10) of floating-twin disc and fixed-caliper format. Utilises one or more single wire springs (44) as resilient means to bias the two floating friction elements (18, 20) with respect to the fixed caliper (34). Each spring exerts a differential resilient effect on the central friction element (20) with respect to the floating side friction element (18) by virtue of differential connection arrangements, thereby meeting the differential springing requirements.
