Brake Fluid Leak problems of the 2007 Honda Ridgeline

1. At a constant speed of approximately 45 mph, level surface or slight uphill grade, transmission in od, torque converter locked, I experience a serious vibration and audible tone coming from the engine compartment. In addition, that tach reflects a slight pulsation in engine rpm at approximately 1500 rpm. This is the same description as in the odyssey and element recalls which indicates a faulty torque converter. 2. Brake pedal is spongy and soft. When applying brakes, the pedal drops to a level close to the floor. Braking is minimal. When applying 2 pumps of the pedal while braking, the pedal becomes firm and high, as it should. Braking then appears fine. My brakes were bled two times. On both occasions, a considerable amount of air was removed from the lines. The problem quickly reappeared after bleeding the brakes. There were no brake fluid leaks anywhere, just air in the lines. Similar to the odyssey and element recall, the vsa modulator is allowing a small amount of air into the system on initial start. 3. The right rear outer brake pad wears prematurely. My Ridgeline just turned 100k miles. I recently installed the third set of rear brake pads and the second set of rotors. The caliper pistons and attaching hardware moved freely and was free of corrosion. I believe issue # 2, air in lines, may contribute to this. The brakes with the least amount of air in the lines are performing the majority of the braking, therefore wearing those particular pads before the others.
