Not sure about the per-aircraft options, etc. BoneDust indicated that it felt like the brakes were always partially on. My experience was the same. It felt like the brakes were on, and made it tough to turn a 180 and get lined up on the cat properly. Turns out, the brakes were on, and released only when I hit the toe brakes. After I inverted the brakes on my Crosswinds (via the MFG Crosswind calibration software) the F-14 can now taxi just fine, on the carrier and airbase.
