ABSTRACT:
A multiple disc brake apparatus provided with at least one rotor rotatable with a vehicle wheel, a housing secured to an unrotatable portion of the vehicle, at least two pads supported by the housing and located on both sides of the rotors, a cylinder member secured to the housing, and a piston member mounted on the cylinder member to urge each pad against a frictional surface of the rotor responsive to a supply of a pressurized brake fluid to the cylinder. The cylinder member includes a main part fitted sealably in the cylinder member, a sub-part disposed between the main part and the pads, and a first heat-resistant member provided between the main part and the sub-part, in such a manner that the main part, the first heat-resistant member and the sub-part are arranged in series. The cylinder member is independently provided from the housing, and the cylinder member is fixedly secured to the housing through a second heat-resistant member.
