Suggestion is to gravity bleed or vaccuum bleed the brakes as it sounds that you have air in your lines still. I just dealt with what sounds like the same problem on my truck.
I am looking for a good welder to weld a crack in my truck (Chevy K1500) frame. The crack is located in front of the drivers side upper shock mount. The crack is approx. 1.5" long on the bottom of the frame and starting to go up the side. I need to get this fixed asap for a reasonable price. Please call me at 614-657-8305 or pm me with prices and locations.
