You're right. In was told the RABS valve was the rear proportioning valve assembly. I should've just said RABS instead .....evidently had another brainfart :-)- madmax401

My firm creepy pedal still occurred after bleeding the system a few times my manual foot pressure. I ended up using my buddies "BG brake bleeding machine" to pressurize the system. Just 3 tiny bubbles came out of the proportioning valve. Took the truck for a test ride and was still a firm creepy...- madmax401

I think you may have nailed the creepy pedal issue without a doubt due to my laziness. Too many projects got me overwhelmed/buried. Perhaps this weekend I'll get those rear wheels in the air. That new low vacuum warning switch should be here friday. You're probably right again that it was...- madmax401

I have less than a thousand miles on the truck since I last pulled the dorms and adjusted the shoes to snug the drum. Did that when I changed a leaky wheel cyl. I'll definitely recheck everything to make sure they didn't back off. I appreciate the insight- madmax401

No , I haven't done that . A few months ago I replaced the proportioning valve due to the rear brakes not getting any fluid pressure master was working fine. That solved that issue. Then my pedal had great pressure initially after 1 pumps but would start creeping to the floorboard. We bled it in...- madmax401

That would certainly explain why my AC doesn't get as cold as it should and also why there's more heat in the cab than there should be unless I have all heater controlls off. I'm goin to attempt to chase down any and all vacuum system leaks and try to measure vacuum readings somehow. I found a...- madmax401

I have also noticed that the white plastic vacuum line has been eaten or just dryrotted. The low vacuum switch looks older than dirt..... Definitely want to replace it any regardless. Any suggestions on recoupling the white vacuum by slipping rubber vacuum line over the ends ? It didn't appear...- madmax401

My pedal is rock hard and all the major components such as master cylinder,power brake booster,proportioning valve and Vaccuum Brake pump all replaced this week. Still rock hard pedal and not as spongy as before. Low vacuum warning switch 12A182 is the only other component it could be. No...- madmax401
