Parking Brake Valve trouble potential

[SierraYankee]

Greetings Folks;
anyone have a diagram or sketch of the C337 parking brake valve.?
Need to see if a worn valve could leak 5606 fluid simultaneously from both Left and Right hydraulic lines.
THANKS in advance

Yes it can if the seals are bad. Mine had a bad bore and I sleeved it. Make sure to undo the fittings to get the small pins out so you can pull the actuator rod out. The actuator rod has the seals on it.

Thanks for the info Dan.

I’ve had to reseal several valves. As a matter of fact I had a spare valve I would rotate around
