The 26-C Brake Valve, Figure 1, is a self-lapping type in which have been incorporated many modern design improvements. These include the replacement of the rotary valve by cam-operated вЂњOвЂќ ring-packed spool valves and cam-operated poppet type valves to provide the control over the locomotive and train br akes. Also incorporated - Be sure the Vacuum Release Valve (black knob on underside of brass pump body) is securely closed. - Begin pumping action to create maximum vacuum as displayed on the gauge. - Once vacuum is accumulated, loosen the vehicle bleeder fitting slightly to open it and allow the vacuum to draw out fluid and air from the brake system.

The effecTs of a vacuum boosTer on brake pressure The brake pressure that comes out of the master cylinder is a result of вЂњmanual brake pressureвЂќ and вЂњboosted brake pressureвЂќ. вЂњManual pressureвЂќ is the pressure generated by pushing on the brake pedal with out any extra force from the booster. The air over hydraulic system is a common application for trailers being towed by light and medium duty commercial vehicles equipped with air brake systems. Components of the air/hydraulic system are trailer mounted and consist of a compressed air storage tank, a control valve, an air chamber/master cylinder assembly, hy draulic lines and
