Page 287 278 OPERATION Both circuits are piped into a dual brake valve, which simultaneously applies front and rear axle service brakes during each brake application. In the event of a failure in either one of the circuits, the other circuit becomes the emergency circuit for applying the brakes.
Page 288 OPERATION 279 W3005171 Master Warning Tell-Tale An important feature of the brake system is that an automatic spring brake application does not take place as a result of an air loss in only one of the two circuits. In this case, brake control remains in the foot brake valve.
Page 289 280 OPERATION Foot Brake Valve The foot brake valve is directly connected to the brake pedal. The valve gives a progressive output against the pedal travel. This allows better control of the pressure in the first half of the pedal travel. In the last half of the pedal travel, the pressure output increase is faster.
Page 290 OPERATION 281 1 The best possible stop will be made when the first brake application is as firm as the speed and road condition permit. Then, ease off as the speed is reduced. Never apply the brakes lightly at first and increase the pressure as the speed diminishes. 2 DO NOT fan the brake pedal.
