4104 Brakes

[pd-drag]

Greetings,

looking for information on the braking system.  the PO has modified my braking system and I am looking for part/model numbers to return to original condition.  specifically
application valve
double check valve
icc valve
cutoff valve
two way limiting
limiting quick release

also the discussion in the GM coach maintenance manual on front brake limiting and two way control valve.
for those using that configuration is it useful and worth installing

thanks in advance

We should probably take this decision with some brakes
Some of the earlier valves were and can be replaced with a new valve that combines some of these you mention and so addressed by application designs in the newer brake valves. So in these changes they may well be great that they are an updated system part. Its a great question and I'm sure your going to get some answers especially with some valve numbers handy.
its Friday so have a good one

? why do want the ICC brakes ,forget about the front axle limiting brakes buses need all the brakes you can have I am old enough to remember the limiting valves they were a PITA.
ICC brakes are a low air pressure 60+years brake technology often called "Hail Mary" brakes in the 50's and 60's

      I was in a different situation. All my braking system was. sly deteriorated - tanks rusting through, metal air lines leaking, valves corroded,  cans shot _ plus the emerg/parking brake was a 5/8" steel rod running from a 3' long lever next to the drivers seat.
      I had to pull it all out anyway so I read a lot of the Bendix tech data, analized new components, got really valuable info and assistance here, and went to Bendix brake school. Now I have a air dryer, modern service/park-emerg cans on the rear axle, modern design valves, safer design on separation of brake tank systems, up to date park-emerg valving etc.

Not cheap but I had to do it and I'd never go back. Ymmv but I'd advise you to think hard about your system.
