I recently took my front left brake in to get the bottom hole redone/sleeved from being stripped. anyways I had no brake problems before this other then the bolt coming off (abs light is on don't know if that matters that much), but nothing wrong with fluids. and I've since drained it all, no bubbles, no old fluid, and still the first press every couple of seconds without pressing the brake the first press can goto the floor with pretty much no stopping power, then the next presses back to back work fine, then i lift off for a couple seconds and the process repeats. I guess I'm asking what could be the problem, any help is appreciated and sorry if i worded that horribly not my strong suit lol

 

You def have air in the brake system and need to get it out.
