Brake system for vehicles

A vehicle brake system housed in a casing, comprising:

• a brake housing formed in an end of the casing, the brake housing having a closed end and an open end;
• a cover mounted to the open end of the brake housing;
• a differential case rotatably mounted in the casing;
• an axle rotatably mounted in an opening in the cover;
• at least one first rotary friction plate mounted to the differential case;
• at least one second rotary fiction plate mounted to the axle;
• and
• a plurality of stationary friction plates mounted to the brake housing such that a stationary friction plate alternates with a rotary friction plate, whereby pressing together of the plurality of stationary friction plates and the at least one first friction plate and the at least one second friction plate brakes both the differential case and the axle.

• a fixing ring mounted to the cover;
• a cam ring rotatably mounted opposite the fixing ring;
• a plurality of ball bearings mounted between the fixing ring and the cam ring, wherein each ball bearing of the plurality of ball bearings is seated in opposing sloped cam grooves in the fixing ring and in the cam ring;
• and
• an operating arm rotatably mounted between the cover and a wall forming the closed end of the brake housing, wherein the cam ring has a projection extending from an outer circumference that is in contact with a side of the operating arm, whereby rotation of the operating arm rotates the cam ring to bring about the pressing together of the plurality of the stationary friction plates and the at least one first rotary friction plate and the at least one second rotary friction plate.
