Brake swap, soft pedal need ideas.

I found this on mark Williams site

1) Air in system. Bleed brakes, making sure that the bleed valve is the highest point.
2) Disc warped (saucer shaped). Replace or surface rotors
3) Calipers not square with disc. Check housing end alignment, both concentricity and squareness.
4) Linings worn on taper. Make sure that caliper is centered over the rotor and the caliper bracket is not deflecting.
5) Master cylinder bore too small creating excessive high line pressure. Match master cylinder to system.
6) Master cylinder deflection. Stiffen master cylinder mounts

Only problem I can see is the 1" master. Im good on all other counts. I don't see how I could still have air.

I sent the better part of 3 days bleeding my MX-6 when I redid the entire brake system. Sometimes you just have to keep going.Also every time you pump the brakes you push the bubble back down so if you are positive pressure bleeding you may just be pushing the bubble back and forth with out actually pushing all the way out.

I was/am using a bleeder that sucks from the caliper out.

did you bench bleed the master?
power bleeders like mighty vac do work well.
