did install Sat morning and pulled the old one out Fri night... woof.

items needed:
10mm wrench for hard lines
12mm wrench for cmc rod adjustment
12mm socket for cmc bolts and booster bolts
10mm socket for cmc reservoir bracket
8mm short wrench for slave cylinder bleeder
swivel for left cmc bolt
needle nose for cmc pin and hard line clasps

unbolt cmc and disconnect pedal. loosen booster bolts as much as possible
unbolt cmc reservoir
disconnect hardline along frame rail
wiggle booster while pulling out hardline
wiggle out cmc and hard line all in one including reservoir... under brake reservoir

swap over needed parts from old cmc to new

reinstall

bleed via slave cylinder

Per ACT, they have come to the conclusion the feedback plate (triangular object at end of CMC) is to blame for failure
