Service Brake and Parking Brake Operation
Service Brakes Released
Illustration 3 g01109434
Brake Control Valve (8) Parking Brake Valve (9) Secondary Brake Valve (13A) Reducing Spool (Left Brake) (13B) Reducing Spool (Right Brake) (16A) Line to Left Brake (16B) Line to Right Brake (17) Pump Supply Oil (24) Proportional Brake Solenoid (26) Parking Brake Solenoid (27) Secondary Brake Solenoid (BB) Cutaway Section (CC) Component Surface (FF) Activated Components (GG) Tank Pressure (JJ) Pump Pressure (KK) First Pressure Reduction (PP) Pilot Pressure (SS) Trapped OilWhen the operator releases the service brake pedal, the position sensor sends a signal to the power train ECM. The power train ECM increases the current to proportional brake solenoid (24). The amount of current that is sent to the solenoid is directly proportional to the position of the service brake pedal.The increased current increases pilot pressure to reducing spools (13). Reducing spools (13) move downward in order to allow pump oil to flow to brake lines (16). The pressure releases the brakes.Service Brakes Engaged

The following text explains the engagement of the service brakes from zero engagement to full engagement.When the operator pushes the service brake pedal toward the floor, the position sensor sends a signal to the power train ECM. The power train ECM decreases the current to proportional brake solenoid (24). The amount of current that is sent to the solenoid is directly proportional to the position of the brake pedal.The decreased current reduces pilot oil pressure to reducing spools (13). Reducing spools (13) move upward in order to relieve oil pressure in brake lines (16) by partially opening the brake circuits to the drain.When the operator pushes the service brake pedal all the way to the floor, secondary brake solenoid (27) is energized. Secondary brake valve (9) allows any remaining pilot pressure to flow to the drain. Reducing spools
