Hey all. I need a little help. Yep, I've searched. Yep, I read the manual. I need experience talking to me from someone who has had this issue. Please read all my info-it does not seem to match up well with any other posted problem, although I may have contributed to the problem!
1. I have air blowing out the vent tube from the master cylinder constantly. Not a lot, but still blowing out.
2. My brakes are EXCELLENT.
3. I have power bled everything, new DOT 5, and no leaks anywhere.
4. I removed the air control portion of the air pak. Exhaust valve was not stuck, all clean inside, and piston glands looked worn but OK. I did not take apart the air pak to see inside the big cylinder or the hydraulic end. As I said, brakes are great.
5. My gauge never goes above 35 psi or so.
6. If I disconnect the output line on the compressor I can hold my thumb over the port and basically block it off. Doesnt seem like enough air. I have a Midland brand OE governor on the firewall-havent disassembled it but did peck on it. Compressor never changes its tune.
7. Here is where I may have shot myself in the foot. I ran a 1/4 nylon line to the air pak from the tank replacing the original copper line which I damaged. To do this, I tapped the fitting ID in the valve 1/8-NPT and screwed a push connect (all DOT approved) in to the original fitting. Could it be that pressure alone is not enough? I dramatically reduced the volume of air available to shift that valve.
8. My brakes do not drag, lock up, or otherwise act abnormal. I may not have as much boost as I should, but I can slide it on gravel.
9. Ive soapy watered it to the point that it is VERY clean underneath!! No leaks!
Do I need to rebuild the air pack?
Is my compressor bad?
Is my governor bad? If so can I get a new Midland?
Is that small line messing with the valve and venting off what the compressor makes?
Any and all help is appreciated. Please see the pic on "The Deuce" where I posted this as well.
