Hi there
The priority valve was removed and cleaned with no evidence
of debris also the pressure test on the ls line on the steering being move sometimes pressure and sometimes nothing unless another serviced was moved
I gather that the pump on stand by pressure supplies the steering orbital and then when steering being move charges it to system pressure
there is a odd problems with the brake and we are wondering if the main valve is leaking (thus loosing pressure )
JD in england seam to have no idea and looking into system the brakes system is suspect
please help its driving me insane
