Mark,I once had the hydraulic line at the top of the right landing gear strut fail on brake application on the rollout during a loaded landing at Porterville in B-17 Tanker 65.All of the hydraulic fluid went overboard and there's no backup for the brakes on the B-17s that I've flown.So,I had no brakes at all.I managed to do a more or less controlled ground loop at the end of the runway to the taxiway using the throttles.It wasn't pretty,but it worked.
So far,so good.The real trick was trying to stop on the narrow taxiway.Even with the tail wheel locked and no wind,the airplane wanted to drift off the taxiway when I shut the engines down.I was only moving about 5 miles per hour,so full rudder and aileron had zero effect.I had to quickly fire up a couple of engines while my co-pilot found a wheel chock in the airplane and managed to toss through the front entrance hatch to under the left main wheel.
It's a really helpless feeling moving along with zero control.You can't even retract the gear if you are headed for something expensive or about to go over a cliff.Someone once told me that all friction in the wheel bearings disappears when you step on the brakes and there's nobody home.I think that he might have been fight.At the time,I thought about a story of a Liberian oil tanker that ran over a sailboat and it took about 5 miles before they could stop.I can believe it.
This is actually a picture from the nose hatch of T68 at Alamogordo in 1980, but it gives the idea of tossing a chock under the left main wheel stopping T65 with no brakes

Here's a shot of T65 at the Porterville Tanker Base in 1982 at about the time of the hydraulic line failure.
