I ordered a new park brake regulator from mci for a friend of mine. He is installing it himself. Does anyone know if the regulator comes pre-set ? I believe the correct setting is 85 psi. Thanks for your input. Marc
I never got one from MCI that was pre-set.
I always check 'em after I replace them - any adjustable air pressure regulator.
Yes, 85 psi is the correct setting. Should be a fitting next to valve that you can hook up an old a/c line and guage to it.
