    I'm working on a sinking brake pedal issue. New master cylinder, new abs unit, new soft lines up front, blead and still persists. Does this abs unit have to be auto bleed by a diagnostic tool to solve this problem?

    I found quite a helpful post on this over on t4r.org. Certainly worth a read through. Hope this helps you sort your problem

    I had this issue on my FJ, turned out to be a miniscule leak on a new brake job. Caliper connection, if I remember correctly.
