    In response to junky


these are all great suggestions, I will try to upload pics hopefully after work today.

To answer some of the questions:

1. Yes, I rebuilt brakes to factory specs, hoses, wheel cylinders, shoes, OEM drums turned, etc. With new replacement parts.

2. The MC is manual, no booster.

3. I sold the oem master cylinder and separated the front and rear brake lines at the junction box for safety, so undoing all of that would be a lot of work. Brakes fine after those mods.

4. the shoes were not contoured because shops here in CA don't accept those jobs - at least where I went. I beveled the ends of the linings with a file.

5. The pedal travel and parking brake travel, and stopping power is all satisfactory IF all star wheels (verified correct placement) are adjusted to a slight drag on the wheel.

The rear brake hardware limits the adjustment at a point where the pedal travels about 6-7" to stop.

IF GM intended it that way, then all is working as it should. I just expected this self adjusting hardware to expand the shoes to leave pedal travel at about 3-4" which I liked and CAN be achieved IF I adjust star wheels myself, which is OK but a little more involved than the self adjusting feature that I was hoping for.

So is brake pedal travel of about 6-7" normal for self adjusting brakes? I just don't have access to any original set ups to compare mine to....

my next step is to mark the star wheels with a scribe and see if the mark rotates or not using the self adjusting feature.

thanks again!
