The brake/pilot pump (1) is a variable displacement pump that provides oil to the brake combination valve and pilot oil to the steering and implement hydraulic systems via the brake combination valve. The brake/pilot pump is attached to the steering pump (2) on the right side of the machine below the cab. The brake/pilot pump replaces the fixed displacement pump on the H Series machines. The pump compensator valve (3) controls the oil flow to the brake combination valve. When pressure in the brake system is less than approximately
