Front brakes seized after rebuild

[Mr_Riley]

Hey all,

I have scoured the forums and online threads but can't come to a solution.

I have a 99 Sahara that I replaced the rotors, pads, calipers, soft lines in the front, and master cylinder. The reason behind the upgrades is that I have been going through brake pads every 4-6 months with simple highway driving - nothing spirited because it's still a wrangler.

I have replaced numerous pads and rotors without issue but now after everything is reinstalled and bled, the front brakes are locked up and it will not drive forward or reverse. It's like I'm doing a brake stand.

We have bled several times, enough to put 64+ fl oz through the system and no bubbles or air pockets.

Brake booster is checked and good
Master cylinder is brand new
Proportioning valve is checked and good
Hard lines flow both ways
Soft lines to the calipers are brand new
Calipers are brand new
Slide pins are greased and good
Pads/rotors brand new

Just at a loss for what the issue could be here.

Probably installed early rotors, 97-mid 99 on later unit bearings. Later being 2000-06 which require a shallower rotor. Curiosity forces me to want to know how more bleeding fixes locked up brakes?

Measure inside of rotor hat to top of rotor. You likely have the 3" versions and need the 2 3/4" versions.
