Brake Pressure Modular Valve
The Electro-hydraulic Control Unit (EHCU) is located on the frame below the drivers side and regulates hydraulic pressure in the brake system during
an antilock stop.
The BPMV is split into 3 hydraulic channels; right front, left front and rear brakes. Each channel has an isolation valve and a dump valve. The front
channels share a low pressure accumulator, attenuator and pump. The rear channel also has a low pressure accumulator, attenuator and a pump. The
rear brake channel of the BPMV controls both rear wheel simultaneously.
