With Randy Brooks' help, we got the left brake bled and operating properly. The pilot's left pedal had tightened up overnight and was working properly, but the passenger's left pedal was still flat. Randy and I attempted to bleed the left brake line thru the bleeder valve and depressing the passenger's left pedal, but that did not result in any air or fluid coming out. Fluid would be pushed out when the pilot's left brake was applied. Our guess was that there was a large air bubble caught in the line between the two left brake pedals.
Randy had brought his pressure bleeder with a few different size fittings with him. The bleeder bottle was filled about 1/4 full. I screwed in an AN840-4(?) fitting into the brake reservoir. This fitting allows a tube to be slid onto the end. A 3/8" tube was placed on the fitting and clamped in place. The tube was also placed onto the hose fitting on the pressure bleeder. The reservoir had already been filled to the top. The pressure bleeder was pumped up to about 12 psi. The left bleeder valve was opened and the passenger's left pedal was depressed continuously many times. This resulted in some fluid finally coming out. Pumping of the pedal was continued and air finally was pushed out thru the line. The left brake line was finally completely bled of air. The process was repeated on the right side. There was only a little air left in the right line, but it was pushed out.
All four brake pedals now properly apply brakes!
