I have a 1994 yj born with a 2.5. I bought it originally with a 9 in in the rear and a 9/44 hybrid front axle with what I believe are cj front brakes. Before my coil over build the brakes worked ok. After sitting for 2 years I now cannot get my brake system to bleed well enough. my master was dry as I changed all the brake lines and wheel cylinders etc. Before I go buy a new master cylinder because I'm assuming it's bad from sitting dry so long does anyone have any input on if the 4 cylinder master cylinder is good enough for 37s. Or does there a trick to bleed the system or is it just that I need to bleed the master before I bleed the lines etc there is so much info online it's hard to know what to do first to trouble shoot.

Any help is appreciated

could have rust from sitting dry, or leaky piston seals. Usually the MC will gravity bleed if it sits with fluid in it for a while.

I always bleed the MC first, then bleed the wheel cyls/calipers starting at the furthest from the MC and working my way to the closest.

Usually, the pass rear is the furthest away.

Update: I pulled the MC and the found a broken c clip that hold the MC plunger in place. I can only assume since it was broken and not depressed like it was supposed to be it was letting air in the system. Today i'll be getting a new MC, bench bleeding it, and see what happens.
