Yesterday and today I finished up bleeding the brakes. My 1st attempt was an all day afair and I still had bubbles in the plastic lines. Yesterday I stopped in to see Jerry and Mickey, and Jerry pulled out this pressurized brake bleeder that he machined and welded himself! The fitting from the bleeder fits secrurely right on the bleed valve from the brake. But 1st I secured the Bonaco lines to the landing gear with tape. I seriously thought about using adel clamps, but I was concerned that they would make the line interfere with the gear legs. So I ended up with the tape again. I connected the overflow tube to the top of the brake reservior with a fitting from Ace Hdware, and safetywired a piece of 1/4 tube to it, Stuck the other end in a bottle taped to the leg of the stool, I pressurised the bleeder with 5-15 psi from the compressor, then filled it with 5606 and hooked it up to the left brake. I opened the valve and watched the overflow tube until it ran clear. I closed the valve, and then pumped both brakes to try and work out any air trapped in the valves. and then opened the valve again. Some minor bubbles appeared but not much. Repeated the process on the right side with same results. After removing the bleeder, I worked both sets of brakes several time to again get any air in the cylinders to move and then let everything sit over night. Today I went back out and hooked it all back up an re did the process to see it any bubbles might have settled in/formed during the night. Only got some very small minor bubbles. Tested both brakes by sitting in cockpit and applying pressure, they seem to be good to go.
