Did you use a power-bleeder?

Did you bleed the airpack also?

I had planned on bleeding mine with compressed air on the master cylinder. I thought that opening the rear right wheel cylinder (furtherest) from the master cylinder would get most of the air out on the first try. Then doing the rest of the wheels to complete the job. By the way, where did you find a rebuild kit for your master cylinder? Are they a cross reference number you would be willing to share. Having dial up its hard to navigate around on here.
1/8" stud to an 1/4" adapter will allow you to use an air quick connect. This will screw right in the top of your master cylinder cap.
