Re: 77 GMC brake issue
I took the bleeder nipple off, cleaned it up... Fluid is flowing from it now.
Going to do the prop. valve reset tomorrow again..
One thing I was curious of,
If I'm doing this test, and i find a clogged or slow dripping line, should the truck be running or at least power on so I can see whether the brake light will go off or not.
Or rather should I just do it with engine off and hope to hear the "click" noise...
Also I read on another forum that driving about 25mph then slamming the brakes can reset the valve, i'm unsure of the logic of this but he swore it works...
Both front brake lines were outputting fluid at a very high level, where the two back ones seemed to be 75% less fluid than the front.
Motornut;
I'm unsure at this point if they are reaching the drum.
Im pretty sure the ebrake is good, forgot it on one day and realized it when the truck wouldn't accelerate in reverse.
