On my truck, two fingers is the entire life of the pads.
Ron: We went through this whole bit last time. If you want reassured that there is nothing wrong with your brakes, you are in the wrong place. We want your truck to be safe and for you not to die in a crash.
If you have to pump the brakes up, they have air in them. If you have gotten them bled and flushed multiple times with no change in that behavior, you have a leak that is letting air in.
If you are still losing fluid on the scale of it being measurable in 4 months (the last time you told us you had the system flushed and bled was 6/20), your leak is non-trivial. It could very well only leak under pressure and that is why you don't see it on the floor, but you are leaking.
Please Ron, get this fixed correctly before someone gets hurt.
