Re: [Chevelle-list] Proportioning Valve Problems

The proportioning valve has a button on the front of it. You need to hold the 
button in to bleed the rear brake. I believe it is for safety incase one of the 
lines break all the fluid wont leak out

  Hey Guys

  I did a front power disk brake conversion on my '71 Chevelle. Everything fit 
together very well and looks as it should. My problem is I can't bleed the rear 
brakes. I can crack the brake lines ahead of the wheel cylinders, and get fluid 
when the pedal is pumped, but can not get any air or fluid out of the bleeders 
on either rear wheel cylinder. I have completely removed the bleeder valves to 
look for an obstruction of some sort, and they are clear. The visible portion 
of the needle valve on the proportioning valve block does extend slightly when 
the brakes are activated, but it only moves about a 1/16th of an inch. Is this 
the way they are supposed to work ? The kit came with a new proportioning valve 
for front disk/rear drum brakes that is supposed to be correct for all GM "A" 
bodies of this era. I suspect this to be the problem, but don't know how to 
test it. Any ideas ?  I am stumped.

On mine, there was a rubber covered button that I had press to get fluid to
go to the rear.  Not sure if that was reqequired or just happened at the
same time.

  Larry,
   
  Ill snap some pictures today for yah. Mines right underneath the 
  master cylinder, held up by the lines. However I hear this is bad, because 
  of the p-valve jumping around, over time the lines will crack. There is a 
  L bracket that mounts right there, that you can actually bolt the 
  p-valve to also. Or you could always mount it low on the frame, which is 
  what they did stock. Once my camera batteries charge up I will send you 
  some pictures!

Re: [Chevelle-list] Proportioning Valve Help

[Larry Shouse]

I appreciate it. I am curious where you have 
yours mounted. I've seen a picture of one where it was positioned directly under 
the master cylinder, with nothing more than the brake lines themselves holding 
it in place. I would imagine most people have it mounted on the 
frame?
 
Yeah, if you don't mind, I wouldn't mind 
seeing a picture or two of your setup.
 
Thanks
Larry

John,
I 
looked at the stock one from my 71 that I replaced.  Not the same.  
Mine has Bendix cast in the side.

Sorry John, I have no idea about the

give them that part # & see if they'll look it up for

There is a rubber boot on one end, with a pin switch
under it.
Just push in the switch.
You can reach it from the top of the engine
compartment.
