Re: Faulty proportioning valve or master cylinder?
Did the wheel spin free with the caliper off?
I'm in the process of doing my '86. Rotors were scored up, so got them turned. I only ask because mine wouldn't turn with the scored rotors. Caliper removed they turned fine, that eliminated a bearing issue.
Check this thread, might give you another direction. http://67-72chevytrucks.com/vboard/s...d.php?t=501102
