ABSTRACT:
In a disc brake a piston is axially slidably mounted within a cylindrical space in a cylinder with an opening in the end of the cylinder communicating with the space. The piston is arranged to move axially through the opening and to press a friction pad into engagement with a disc. The piston is in sliding contact with the surface of the space in the cylinder body. A boot protector covers a boot extending between the inside of the cylinder body and the piston. The boot protector is formed, in part, of a rigid ring body fixed to the opening in the cylinder body in which the piston is housed and of an elastic ring body secured to the inner circumference of the rigid ring body. The boot protector covers the surface of the boot facing toward the disc. The boot covers the surface of the piston disposed in sliding contact with the surface of the cylinder.
