What happened that made you work on your brakes? Leak? Did you try bleeding the master cylinder?

I am guessing a helix is a euro version 2R5 of a tacoma. Only question I have is, is it diesel vac pump or gas engine vac driven booster?

I am also guessing there might be a diesel in there as all if not most have that option where as we don't. Never seen a diesel in a canada tacoma before.

I need to know this as masters may differ from one option to the other. You may have reversed a cup seal in the master when doing the initial bleeding proccess. That could account for your brake pedal going to floor if no outside leaks are found and you are sure no air is left in system. There is no automated bleed process to speak of for the abs unit, not like a GM.
