Brake pedal height question

Looking at the pic in post #2, I see the brake pedal [ unapplied ] is well above the acc pedal. I would think that is normal height & you wouldn't want it any higher.
You seem to losing about 2.5" - 3" of travel, before the brakes apply.
There can really only be there reasons for that:
- what I said in post #16
- some thing wrong the caliper piston/retraction process creating a lot of clearance that has to be taken up with m/c travel
- brake pedal p/rod travels too far before it contacts the rear piston in the m/c
