I swapped my rear end out to a 8.5 4.11 posi from a 8.2. Added right stuff rear disc kit / and PV valve at the time of swap. Why not? Makes sense right?
Worked fine for few 100 miles. No issues. Driving around breaking in the diff and the rear brakes start to drag. I made it home with red hot discs. Assumed the issue was a failed brake hose. Replaced the hose coming from the chassis, calipers, rotors, and pads. No pedal ever since.
I have since replaced the master cylinder twice. I bench bleed it before I put it on. Tried bleeding the brakes with a friend a few time with no luck. Bought a pneumatic bleeder that hooks up the air compressor. Use a little grease around the bleeder and I can drain the master in about 1-2 minutes. I have bled the brakes so many times I cannot remember how many now.
I do not have any leaks that I can see. I have checked checked and re-checked and gone thru about 2 gallons of DOT3 fluid.
I obviously have a leak somewhere. No physical leaking from brake lines/hoses. Master is brand new and bled. Can a PV valve cause this? I bought PV72 from right stuff when I did the swap.
Any ideas?
