Abstract
The present invention provides a disc brake with an integral parking brake, in which a push rod, a push rod biasing member and a spring cover are formed into an assembly in the form of a single cartridge. The push rod is divided into two separate bodies, namely, a front body portion threadably engaged with a clutch member and a rear body portion engaged with a cam rod. In this disc brake, it is possible to prevent a loss of an output force of a piston under a high fluid pressure. There is no need to increase a diameter of a piston for compensating for such a loss of an output force of a piston, and a reduction in size of a disc brake can be achieved.
