hey no worries... I've responded to posts years old if it was open ended...
so I have all the brake lines, connections, joins hoses and everything all plumbed up. I had alot of problems with leaking connections..not only with all three of the flares I made, but with store bought lines & brass fittings/connections... It's the rear lines that are giving me the most trouble. But also the lines from the m/c to the prop valve, and then out the rear of the prop valve...
can someone tell me why

&

have different sized m/c & prop valve connections between them & also different size for rear line? WTF??? why isn't the entire system ALL 1/4 or ALL 3/16? Right now I have around 5 different sizes between the m/c, prop valve, and rear line...
anyway, I've bench bled the m/c, I've individually bled each brake, starting from the brake farthest from the m/c.
and have just finally sorted out a huge pile of other problems and finally have all four tires on the ground... lemme tell you, a front axle swap that includes a disc brake upgrade may seem easy on paper, even to a novice, but in reality is VERY difficult, at least when you're upgrading from the 60's to the 80's !!!
I'm shy of pics right now. I'll take some today for sure and post em up soon. I'm very much hoping to have this truck on the road today...
