I have been having a little trouble with the rear brakes on my '83 6.2L, and I was wondering if someone more knowledgable than I might have any ideas. /forums/images/graemlins/thumb.gif Not too long ago, my brake light came on, and the rear brakes stopped functioning. I reset the Combo Valve, checked the whole rear system for leaks and kinks, and I even pulled the Master Cylinder apart, cleaned it, and checked all the seals (they all seem to be in good condition). After putting the whole thing back together and bleeding both the front and rear brakes, No Rear Brakes! /forums/images/graemlins/angryfire.gif Has anyone experienced anything like this before? I hate to take it to a shop and give them my life savings, especially if it is a small detail that I have missed somewhere.
