Kawi 4 piston caliper (Tokico)

[masters6RR]

Having problems with a tokico 4-P caliper.. Pistons are not retracting, and heating up the fluid until the lever goes sloppy... Not much build up on the pistons, so dont think thats the issue... When pushing the pistons in by hand on the left side, the right side pushes out... I can't get a both sides pushed all the way in flush.. It's weird.. Banjo bolt, lines all from Bill at FTI.. First time I've ever had this issue..

Running the FTI dual quad bracket w/brembo footbrake..

Just changed from 8 piston to 4 piston HB, and ever since it's been a bitch.. Anyone run into this problem.....?
