Proportioning Valve ??

[JohnnyF]

So I have a Mechanic working on my brakes, had most all the parts for the job(4wheel drum). Now I couldnt find a valve that was for all 4 drum, the only one I could find even in LMC was one for drum in the rear and disc in the front. Will this work ???

Also had my gas can dipped and boiled and now it leaks, really sucks

No a proportioning valve for discs in front and drum in the rear won't work on a 4 drum setup. You'll need to get one for a 4 drum setup.

You might be able to seal the gas can with tank sealer.

POR-15 FUEL TANK SEALER or other brands are available on the net.

i have seen the pressure differential block on that auction site. i have been know to get them from junkards for others who cna get the lines out of thiers. you can take apart clean and replace the orings in the pressure diffential valve pretty easily. here is link that was posted awhile back that shows how to do it. althought this isnt the same valve it can be rebuilt the same exact way. http://www.musclecarresearch.com/valve-rebuild-wagner i cant think of who it was that originally posted the link. but they also showed how they did thiers.

Would a random adjustable proportioning valve for any front disc, rear drum work if I know the specs of the preasure.
thats my second question, what are the preasure specs for the rear drum and the front drum for factory or normal settings. Then, what are the specs of the front disc for the LMC part that I got to see if that would work.
I either need to return this LMC part, or see if its close ill use it, if not then i need to rebuild my old valve, or buy an adjustable one and make it work

using all four drums doesnt require the use of a proportioning valve. only the pressure differential valve. i don't know the rest about the pressures. but generic pro valves that are adjustable are made for fine tuning the system and are suppose to be used in conjunction with the regular pro valve oon trucks with discs on front and drums on back.

Ok well I might be saying it different then. so i just need a new preasure differential valve for my 4 drum, or I should rebuild the old one by cleaning it out and putting new o rings on it like the link you sent.

i dont look through the vendors catalogs that much. so i am unsure if they sell new ones. myself i would rebuild mine. unless it was broken then i would get a used one and rebuild it.
