ABSTRACT:
A disc brake of pin-sliding caliper type having a boot protector including an extension of a liner disposed between a side end surface of a brake pad and an opposite torque receiving surface of a torque member movably supporting the brake pad toward and away from a friction surface of a disc rotor axially thereof. The boot protector protects from heat a boot covering an exposed portion of a slide pin which guides a caliper to urge the brake pad against the disc rotor. The protective extension of the liner extends along an axis of rotation of the rotor away from one end of the torque receiving surface remote from the rotor axially thereof, and is interposed between the boot and a heat source such as the brake pad and the rotor. The liner is preferably provided with a resilient section biasing the brake pad in a direction parallel to the surface of the disc rotor to thereby serve as an anti-rattle spring. The boot protector may further include another extension of the liner extending substantially radially outwardly of the rotor away from another end of the torque receiving surface proximate to the periphery of the rotor radially thereof.
