We replace a couple wheel cylinders and rebuilt the master cylinder. When we took the truck out the brakes built up and started smoking. We opened the bleed screw o a couple wheels and it squirted fluid out. the brakes were okay for a few miles and started smoking again. Had to bleed a little fluid again. How full do I leave the master cylinder? Is there something else I need to look at? 3 of four wheels were very hot. Thanks for suggestions.
