So I just finished up some brake work on my Bronco. Keep in mind I have the GM disc brake conversion up front. Here's the situation: I had a leaky front brake line. Decided that I would replace both of them with SS braided lines. I also decided to replace the pads in front, and add a GM style proportioning valve and thus, ended up replacing the M/C (Corvette style). I also replaced one caliper because it got brake fluid in places and that ate some of the lower rubber bits. Problem is, I still have a super spongy pedal. I've bench bled the M/C twice and have tried bleeding this thing four times (twice with a vacuum pump, and twice with someone in the seat pumping the brakes). I'm getting a little frustrated ! Is there something I'm missing or not doing?

Make sure you have enough pedal travel to get the air out. If you have an adjustable length rod you can raise the pedal position to push more fluid.
