Hi Clark, you are correct there is a flow divider in the MCV valve that splits the 9 GPM output of the hydraulic pump into 3 GPM for PS and PB and 6 GPM for 3pt and remotes. The brakes are supplied by hydraulic oil from the return side of the hydraulic oil cooler in front of the rad. The brakes are also a dead end circuit so any air that gets in the brake system stays there until the brakes are bled. Re your problem, try activating the remote control valve until your hear the relief valve squeal. Sometimes this will dislodge dirt stuck in one of the MCV valves. If the above dosen't cure the problem then it is time for diagnostics with hydraulic flow and pressure guages to determine if it is a weak pump or MCV valve problem.
