So, using the long tubes method, I got my brakes bled tonight. The pedal is *really* solid.

But, when I went to each caliper, the Drivers front caliper was tight against the rotor. Passenger front was dragging, but not as much. Both rears were dragging a little. On each rotor I was able to turn it, and it started to come free. However, especially the drivers front, they are not free wheeling.

The rears are easy, I just re-vent them.
The fronts, though. Whats going on there?

I was really stomping on the brakes getting the prop valve bled. I can't imagine that I damaged something. According to Haynes there is no front adjustment. What is to keep them from dragging?

The pedal cluster has also been rebuilt and bushed with bronze bushings. Everything with the brakes has been renewed (rotors, pads, calipers [ E.Shea in the back, I rebuilt the front] hard lines, soft lines) except the prop valve (which does not need it).

Can you describe your rebuild process? Did you clean out the knock back mechanism's in the pistons?

The fronts will rely on a bit of runout to knock the pads off the rotor. Are you driving this or is this just garage testing at this point?

Make sure you adjust the rears on the high side of the runout and adjust to .004"
