Disk brake devices.

摘要

The invention relates to a disk brake device (100) which makes use of the excellent heat insulation of zirconia based ceramics material to effectively insulate braking heat generated during braking, thereby avoiding any increase in the temperature of the brake fluid contained in a hydraulic chamber (114), and is characterised in that a coating layer (138) of said zirconia based ceramics material is provided on at least one of the opposed surfaces of the brake pads (130) and the engaging members (112, 118) which urge the brake pads into braking engagement with the brake disk (120).
