I experienced a complete hydraulic failure three weeks ago. I noticed the hydraulic pressure fluctuating between 500 and 450 psi. I pulled the Aux. Hyd. Circuit Breaker and saved some fluid. I didn't follow Wing Commander Gordon's advice- Mea Culpa, Mea Culpa, Mea Maxima Culpa.
I was surprised how slow one must fly for the nose wheel to extend. About 80 kts. Made a no flap, landing and held the nose off until about 30 kts. and turned off of the runway. I had a little hydraulic fluid left and the Aux. Hyd. Pump provided some brakes. Once clear of the runway, I shut it down and got a tow to the ramp.
The culprit was the hydraulic pressure switch in the left nacelle under the Hydraulic Reservoir. There was no metal in the filter but we changed both pumps and replaced the switch. There was also a small leak in a hydraulic line similar to the one described by Ray Mayfield; we changed that one also.
Kindest regards,
Bill

I think that all of them have power brakes.

I have read that Bob Hoover has only two mods to his Strike, one an electric
un-feather pump and two an electric aux. hyd. pump so he had brakes when
flying with both engines feathered.
