Title: Disc brake with dual operating system - has self adjusting device and can be operated by handbrake lever
Inventor: KARASUDANI YASUO
IPC: F16D65/18
Filed: 1976-10-15
Abstract: A disc brake with a self adjusting device and which can be operated by a handbrake lever, has two pistons (2, 3) forced apart by the pressure of fluid entering the chamber (A) through an upper orifice (20'). Fluid also enters the chamber (B) through a lower orifice (20) and initially acts on the shoulder (14) of the rod (16) pushing it to the right. This motion relieves the load on the nut (16) allowing it to rotate and take up brake pad wear. Increasing pressure overcomes the spring (15) and the piston (5), rod (6) and nut (16) are pushed to the left to exexert a force on the piston (2). The pressures in the chambers (A) and (B) can act independently of each other, thus providing a dual system. The brake can also be operated by rotating the cam (7) which is linked to the hand lever.
