It's not at all as hard as bleeding your brakes to get the air out after a complete brake job. First. Remove the fluid in the master brake cyl reservoir. This can be done with paper towels. Don't let brake fluid get on any painted surface. You must use water to remove instantly. Then put a little brake fluid into the reservoir to use as a cleaner. More paper towels to clean the reservoir. 2. Power your new brake fluid into the reservoir. If the fluid you remove at the start was very dark. Forget doing the next step. 3 If the fluid was fairly clean. Put some food coloring in the first fill of the reservoir. Use a vacuum pump, or a helper to work the brake pedal. Start at the right rear, rear brake bleeder. Drain till cleaner fluid appears. Or the colored fluid first shows up. 4 next do the right rear front. then left rear rear, then left rear front. Next the right front, then left front. At this point. If you used coloring. Clean reservoir of all colored fluid. 5 Start at the right rear rear. And repeat as before till all points show clear, and clean fluid. A clear bleeder tube works best. And never let the reservoir run dry. When I take any one of my 4 Yenko's to a track event. I change my brake fluid after every track event. So I have to use the food coloring. In our GMC's. The fluids will more then likely have some discoloration to it. So the food coloring probably will not be needed. Bob DunahughMember GMCMI
