Ok I have a 2008 toyota tacoma 4.0L 4x4. I ran into a problem with my calipers sticking so replaced them as well as the brake line hose, went to bleed the entire system and with assistance I found I had no pressure being built for the rear, no steady stream of fluid it just oozed out basically just dripped. Ive tried everything I can think of from manually bleeding with help, to vacuum bleeding as well as your basic gravity bleed. Btw I did have rear brakes before all this went down. Anyone else have this problem, or have any suggestions or tips?
