I have 2 honda recons and bought 2 disc kits. I can’t build any brake pressure from the kits. There is no air in the line, brand new master cylinder lever, hoses have no leaks or buldges

No one seems to know the problem, I noticed others have had the same problem too.

I feel as if there isn’t enough fluid being pushed into the caliper

If anyone has had this problem and has corrected it, please let me know
