why do i still feel like theres air in my brakes??
ok i replace my rear brake caliper due to old 1 the shaft poped out because a bolt was loose on the caliper and im asuming alot of air got into my system during tat time ,because i seen it leaking for a week untill my brakes finally reached to the floor when i stop,i replaced my whole hub assembly because of bearing went bad,i tryed to bleed all 4 brakes and still fell like there was air in my system when i stop?? ok well i ordered a rear abs sensor for it thinking that would do the trick,installed it and bleed all the brakes again, its still feel likes theres air in the brakes!!! what could this be??????????did too much air get into the system? or is there another problem going on here

If you are not seeing air bubbles during the bleeding process, it is unlikely you have air. What type of pedal feel are you looking for? The brake pedal should not go to the floor during normal braking operation.
With all the work you've done, I'm presuming the brake lines are in good shape. No bulges, kinks or other issues that may cause a different pedal feel.

The brake should be even feeling and as the pedal is pushed for progressive application of the calipers. If it is "surging" there is additional issues to look into. Are the vacuum lines to the booster and ABS-TRAC unit in good shape? This may be a part to look into. You would usually get a warning light on the dash.
Hard to qualify what you are feeling, are the wheel bearings good, warped rotor are the other calipers in good working condition?

I dont know if surging was a good word but just feels like theres air in my lines,there are no brake lights on my dash popping up at all,do you think completly bleeding them fresh should do the trick??? Oh sorry about the caps lol

Simply put, how does the brake feel after all these fixes? Take the car into a shop and have the technician inspect the brake system. You have only stated it feels like there is "air in the lines" but you have not described any additional symptoms to indicate.
What brake pedal feel are you expecting?

That's not air in the lines. Your ABS may be coming in and thus an ABS sensor or unit. It can also be the wheel bearings are shot, front strut bushing as this will allow the LCA to shift position but you would normally hear it clunking while braking and going over bumps. Master cylinder and or brake booster. This is why I asked if the vacuum lines are in good shape to all these components.
I suspect the ABS unit, brake booster, master cylinder assembly and sensor.
