How to adjust tag brake pressure

[luvrbus]

#86. Trailing wheel pressure regulator.  Should be specs in your service manual.

He will need to check his serial number MCI will have dozens of schematics for the same model bus ,I looked at a MCI 12 the lines run from the relay to the tags no regulator in his system

Edit, never mind it needed to be forced from inside a program, wouldn't open one by itself.

Jack, my phone refuses to open the pdf, what software is likely to want to open in?

Happy coaching!

This is great! Some new, obscure, but very important, thing to learn, that mci installed, trying to fix their problems, in the gap before abs happened.

All i would do is confirm pressure is equal side to side, and that it isn't set too high.

All it takes is one slide on an off ramp, and you ruin an expensive tire and forever get to listen to it announce your speed.

I would be way more suspicious of the drive axle relay valve, whether it is delivering a comparable rate of pressure increase in relation to treadle travel.

You're almost on your own, few peeps at ground level have any training or the equipment to first, measure this, and second, evaluate the findings.

I thought Scott had a 92 102c3, but yes, he'll need scematic for his particular model and year. Also he should have a shop manual for his if he doesnt already have one.

I do have the shop manual. But I'm 1000 miles from the bus at the moment and trying to come up with a game plan before I'm back at it. I'm leaning towards not messing with it too much since BW reminded me that I really don't want to be flat spotting my tag tires. It's permanent and hugely annoying (I've done it on a past bus).
