Abstract: A hand brake lever assembly includes a plunger mounted on a support for axial slidable movement and for rotation about its axis and being connected at its one end to a parking brake, a locking mechanism associated with the plunger to retain the plunger in a pulled out position against a returning effort of the parking brake acting thereon and being arranged to be released by rotation of the plunger, a sleeve member secured to the other end of the plunger and having an annular end wall formed with a first annular cam surface and an axial key groove, a handle having a shaft extending therefrom and inserted into the sleeve member, the handle shaft being formed with an axial guide groove and being integrally provided with a cam member which is formed with a second annular cam surface complementary with the first cam surface and is axially slidably coupled within the sleeve member, a first spring for pressing the annular cam surfaces in contact with each other, a release rod axially slidably coupled with the guide

Abstract: A vehicle hand brake lever assembly for actuating the vehicle parking brake. The lever assembly includes an axially slidable plunger mounted on a support and having one end connected with a brake actuating member. The plunger and the support have a ratchet mechanism for holding the plunger at the brake applying position. The ratchet mechanism can be released by rotating the plunger about its longitudinal axis. A handle assembly is provided at the other end of the plunger and comprises a handle having a handle shaft. A sleeve fitted to a cylindrical guide member is secured to one of the sleeve and the handle shaft, and a lock member to the other. The lock member is axially slidably received in the guide member and provided with a cam profile for cooperation with a cam profile provided on the sleeve. The lock member is spring biased toward the sleeve so that the cam profiles are normally engaged with each other to thereby maintain the handle shaft at a predetermined relationship with respect to the plunger.

Abstract: A fluid reservoir for a master cylinder has intergral flanges at the rear and front portions thereof which are able to absorb expansion and contraction due to the change in the surrounding temperature.

Abstract: A fluid reservoir for a vehicle tandem master cylinder is made of a resin material and provided therein with first and second fluid chambers for supplying fluid to the cylinder body chambers. A pinched-in portion between the first and second fluid chambers forms a wall between two fluid chambers of reduced area.

Abstract: An anti-skid brake control system comprises a cylinder casing having a first chamber connected with a master cylinder and a second chamber in communication with wheel brake cylinders, a cut-off valve disposed within the first chamber for selectively interrupting fluid communication between the first and second chambers, and a hydraulic capacity controller including a plunger axially reciprocable within the first chamber and operatively engaged at its both ends with the cut-off valve and a piston reciprocable within a vacuum servo-motor, the plunger being retracted by the piston to activate the cut-off valve and thereafter to increase the capacity of the second chamber to decrease the braking pressure applied to the wheel brake cylinders.
