Part 2 was getting a bit long so I decided to start a new thread......................
Went at them again this evening. Drank beer, threw empty cans at my truck, swore alot, etc.
Anyhow, I took the proportioning valve apart via the threaded end caps and visually inspected the pieces parts. Everything appeared to be in good shape. Removed the sensor and tried to move the plunger back to center position.
Put it all back together (that back cap was a real PITA to get back on) and here's what I have now:
Brake light stays on and no pedal until I pump the shit out of the pedal (motor running) at which point the light turns off, the pedal firms up and I have about 75% of the brakes back. If I let it sit for 10-15 seconds the light comes back on until I pump em' up again at which point it goes off and I get brakes again.
I'm hardly getting any fluid at the rears, lots from the fronts. From what I understand the metering valve will hold off pressure to the fronts until the backs kick in. Because I'm getting no pressure to the rears, the fronts are holding off giving me a real shitty pedal.
So, no pressure to the rears means one of three things:
1) Collapsed rear flex hose. 2) Iso/Dump stuck open (replaced with new unit a few days ago) 3) Proportioning valve f**ked.Pretty sure it's number 3. Gunna bite the bullet and order my $206 valve. Anyone know how to verify if the dump is stuck open without opening the ABS hydraulics and rigging up a block to the valve? If it was stuck open I think I'd have an RWAL code set eh?
Thoughts?
