Thread: brake plumbing questions for my T bucket

Tweet

we are probably talking about 2 dif. things. most factory GM cars put all this together and call it a combination valve. that would include the brake warning light, proportioning valve and the residual valves, but after i go back and read it i guess you don't have the warning light sw. (cut the pressure off if a cylinder fails )and thats the biggest reason to have a duel MC, so if one wheel blows out, the combination valve will cut the pressure off to that wheel, and you can keep on driving. i put a drawing in with this that show the cutoff valve. you don't have to have it, but without it you don't need the duel MC. see if the drawing helps any.

see if this makes more sense.

That sounds alot like what I removed from the T when I did the upgrades...


Here are the components I have attempted to install...
part # WIL260-8419

part #'s WIL-260-1876 for the red 10lbs, and WIL-260-1874 for the blue 2lbs

(T Performance) part # BS1915

... and below are a couple pics of what (sounds like the all-in-one you mentioned) I pulled out (I cleaned it up for the pic )...

http://auto.howstuffworks.com/master-brake2.htm read this braundc, maybe it will make more sense. what you have is what i would put on my round track race car. the valve you took off is what i would have used on my st. rod. so i would have the "The pressure differential valve" that you dont have now.
