I just installed a new set of front pads and flushed out the old brake fluid. I connected 1/4 ID clear tubing to the bleeder valve and had the tubing submerged into container of brake fluid. During the flushing process, there was a good amount of pressure on the brake pedal. The old fluid and possibly air was bled out of the system working from farest wheel to closest wheel from the master cylinder. I bled the each bleeder valve until fresh clean air free brake fluid came out. When I took the car for a test drive and all of the pressure that was felt on the brake pedal has turned into a spongy feel. Where did I screw up?
