D6M Breaking Issue

Yes sir that’s where I am currently. I had a parking break solenoid stuck causing some of the problem and I believe the secondary solenoid is also potentially causing the remaining problem. This tractor sat for several years and getting it back up and moving has been a chore. At the moment I’m waiting on a second solenoid and o rings to check inspect the spools. I appreciate all the help I’ve learned quite a bit in the last couple weeks

Owning equipment really is a learning experience

Alright I have pulled the brake valve, cleaned and disassembled, and found the culprit. Between the valve body and park brake housing are 2 tiny check valves 133-3248. One is no longer checking and cat has discontinued these parts with no successor. Their solution is a 8,000 brake valve assembly. Does anyone know of a place to get these check valves in the aftermarket world?

That's a bummer, although at least you have identified the problem. I doubt if the check valves are going to be available aftermarket. A used complete brake valve might be an option but it would always be a worry that the check valves in said used part might be in a similar condition to what you have right now.

Maybe u can rebuilt the valve, sometimes (at least in my planet) Hydraulic shops install valve cartdriges in place where a built in valve were... Very often this valves are eroded away after decades of usage.
