PURPOSE: A brake control device is provided to perform maintenance by independently removing a load corresponding valve without disassembling a main body unit. CONSTITUTION: A brake control device(10) comprises a pair of relay valves(33,34), a pair of double check valves, a load corresponding valve(15), a first electromagnetic valve group, and a second electromagnetic valve group. A pair of relay valves generate operation pressure for a brake through air pressure generated by a first air supply source. A double check valve delivers the operation pressure from a second air supply source or relay valve to the brake. The load corresponding valve outputs pressure according to air spring pressure. The first electromagnetic valve group generates pilot pressure from the air pressure of the first air supply source. The second electromagnetic valve group outputs the operation pressure according to the output of the load corresponding valve into the pilot pressure in case of emergency. |
