Rancho through another 4 rounds of the JScan ABS bleed. Im at the mercy of how long my wife will sit and hold the pedal for me. I didn't visually see any air come out the lines BUT there was a sizeable increase in pedal firmness. First 1/3rd is still super soft second third it picks up some stiffness and last third is decent. Still not what I would call good or done but at least I'm finally trending in the right direction and seeing results

making progress!

take it out and slam on the brakes to activate the ABS, take some fluid to add to the reservoir if it drops any then do it again.

Dont you have to immediately bleed the calipers after doing that?

I didn't on my JKU, I could hear a pump running, took it on a side road, slammed on the brakes to activate the ABS and it worked.

about a week later I did a motive brake bleed with the diagnostic tool ABS bleed, and they firmed right up.

Another thing, sitting dry for that long may have affected the master and there's a chance it needs replacing
 
When I did mine I did add the J8 booster. Not sure how the pedal would be affected without it, but I have to say my brakes aren't super firm at the top 1/3rd of the pedal travel, but after that they are. I'm still perplexed by the wheel weights hitting your calipers. Did they change rotor size I wonder? There's roughly 1-1/2" between the wheel & rotor on mine

The brakes on my Dynatrac 60/80 never felt as stiff as stock. I think that’s a thing. They always stopped but it’s basically impossible to lock them up like stock. It takes some getting used to.

Yep - my Dynatrac set was the same thing. Also took some time getting used to being in 4lo on an edge of a dropoff or going over the dropoff. It'll stop but you just don't get the warm fuzzies doing it. First couple times you gotta engage the ass brakes on the seat to get em to work right.
