Abstract
A disc brake of a type incorporating therein a hydraulic pressure generator, the disc brake having a pair of friction pads disposed on both sides of a disc to be braked to confront each other across the disc; a guide shaft; and a caliper which is provided with a thrusting piston incorporated therein for pushing one of the friction pads against the disc with hydraulic pressure and is arranged to push the other friction pad against the disc as said caliper is moved on the guide shaft by a reaction to the thrusting action. The hydraulic pressure generator is disposed within the guide shaft and is provided with a cylinder which is formed within the guide shaft, a hydraulic pressure generating piston which slidably engages the cylinder and a hydraulic pressure generating chamber. The hydraulic pressure generating chamber communicates, through a passage means, with a hydraulic operation chamber which exerts hydraulic pressure on the thrusting piston. The hydraulic pressure generating piston is operated by an external force to raise hydraulic pressure within the hydraulic pressure generating chamber for performing a braking action by driving the thrusting piston with this hydraulic pressu…
