All pipe connections from tlie brake pipe auxiliary, the 12x33 service reservoir and and reservoirs are made to the mambracket, which is a fixture on the car,so that any of the movable or operationportions of the valve may be removedwithout disconnecting any pipes. The large emergency reservoir is some-times termed the quick recharge reservoirand the smaller reservoir is called thesmall emergency reservoir, and each res-ervoir has a separate connection with theuniversal valve bracket as well as thebrake pipe and brake cylinder. The brakepipe branch contains the usual cut outcock and centrifugal dirt collector. Theautomatic brake slack adjuster is used onthe brake cylinder and the brake cylinderpipe contains a cut out cock
