I actually did have it capped off. That’s the frustrating part. I bought some vacuum caps off Amazon, capped the hardline, went over to my bench to try and fix the extended brake line fitment and the cap apparently failed because when I came back to the 4Runner there was a puddle of brake fluid. It looks like it only drained from the rear of the reservoir. The front is still full. Seems off to me.
Is there a picture of the shop manual on how to bleed the abs unit?

If you have a 96-98 with the old ABS system (a rectangular box with a bunch of brake lines in and out) it can only be bled successfully with the engine running. I just had a heck of a time getting a small bubble out of mine that was causing a soft pedal. There is no procedure in the FSM for bleeding the ABS, it just says to bleed the lines until there's no more air coming out. Except that the ABS unit sits so high up that it's very hard to force a bubble all the way down to the brake caliper.
