i recently had a break in a rear break line, passenger side, i also replaced the front breaks along with the rear line, i spent over an hour trying to bleed the rear break, no luck. anyone have anything that could help. i bled the front breaks and they run fine, the rear breaks just wouldnt bleed. there is next to no pedal pressure until half way to the floor.

 

Theres a valve in there thats not opening correctly. Try putting it in drive, locking the parking brake ableeding them that way.
