I'm sure this has been covered on many threads but none that I've been able to dig into, as a newbie, that have led me down to a path of success.
Please tolerate me, as I'm as old as my jeep, and I'm just a damned partsmen whom is clearly over her head these days!
Background :
My '86, 2.5, 2WD has been sitting in a field since 2005. It was then towed beside a garage that eventually caught fire...tons of melty issues, all have been worked out but this. I bought "Darnit Daisy" in hopes to relieve myself from a JK fuel mileage of 20L/100 (outfitted for overlanding) daily driver that isn't so happy as a daily. Canadian here. :)
Issue:
. I replaced as much as I could... master, calipers, rear cylinders, new friction, lines from the master to the directional valve under the master. I haven't done the other lines as they cracked fine when replacing the brake hoses and rear cylinders. No leaks. But the front kinda seems to keep pushing air? No leaks visible on the booster area either.
I bench bled the master so many times, I've had hands on deck to assist me with bleeding too. The rears are a-ok while bleeding, pumping builds pressure, pedal drops after the cracking, no air in the bleeder tube or in that side of the master, the rears are happy.
Once we get to the front, there's no pressure building on the pedal, and no pedal drop on "hold". The front brake portion of the master foams with air. Still, there are no visible leaks anywhere.
100% factory system, from the parts diagrams it all looks bueno. The rear proportioning valve is hanging out and dry, doing its thing and probably having a drink toasting our suffrage.
I think I understand the brake bleeding process, passenger rear, driver rear, passenger front, driver front, ignition on, crack front, brake light, bleed rear, close front, go back to passenger rear, do it again
We can't get past the passenger front.
Where do I start diagnosing from here? I'm not looking to get fancy with swaps, deletes or anything that isn't warranted past stock if I don't have to. It's fishing season :)
Thank you for any input you may have, I greatly appreciate it. I'm a bit worn on patience with this 'ol gal, and I'd like to see more road and less garage floor these days. I'm pooped trying to sort it out.
