MFI Trailer Calibers Upside Down

[Captbob]

I had to bleed the brakes due to a new backup solenoid I had to install.. I could not get all the air out so I took the trailer to an expert who showed me that one set of calibers were put on upside down at the factory. The bleeder valves were on the bottom causing air to be trapped in the line. He said all bleeder valves should be on the top. Air travels up in a liquid. He simply switched the right side to the left and the left to the right. Air easily removed and problem solved. He guesses that as the trailer came down the assembly line upside down and then were in stalled as if it was right side up. The dealer installed, at sale, a second set of brakes due to our state law and they were right side up. Their mechanic must have seen no reason to mention it. Can you imagine!!!!!!!!!!!!!

Might not make any difference until or unless you have to change something like the master cylinder or backup solenoid where you get air in the line that far forward.
