try bleeding all 4. do you have any leaks? are any of your calipers on upside down?

I don't see any leaks anywhere and I'm not sher but I don't think they are upside down idk how to really tell though. Ill try and bleed all 4 when i get a chance

the bleeders should be pointing UP not down

Like top side of the caliper not bottom

Well that would be one thing that's wrong then the breeders are at the bottom ... that causes funky pressure?

Yes, air is staying inside the calipers. Bleeders on the bottom, so the air just sits above the caliper bleeder. Switch the calipers to the opposite sides.

keep bleeding it...it maybe easier to do the task with a help. One pumping the brake pedal and the other taking care of the bleed valve or whatever you call it.
