Changed the Brake Hoses on the Deuce

Well, the brake hoses on my deuce and a half were probably original to the truck. The outer covering of the hoses were cracked from age, but they were still fine, except for one. My front drivers brake hose had been apparently rubbing against the rim of the tire for a while, and the hose was worn smooth. So, it had to get changed, especially since the brake system on a deuce is only a single-circuit system. This means that a single brake part failure anywhere in the system means no brakes at all. So, while I had the brake system open, I decided to change all the brake hoses on the truck. I got them all swapped except one hose I forgot to order, then went to bleed them. I had a vacuum bleeder, but after bleeding 12 oz of fluid and still getting tons of air bubbles, I wasn't getting anywhere fast.
So, I checked out a forum dedicated to military vehicles, and found out that you can build a "power bleeder" for relatively cheap that makes the job a snap. Boy, did it! I went to Home Depot and bought a pump-up chemical sprayer, and a couple fittings, and was on my way. The deuce master cylinder cap has a 1/8" NPT hole in it for a vent. So, you hook up the bleeder to that vent, pour the DOT-5 brake fluid in the sprayer tank, pump it up, and go bleed the brakes. I was able to bleed all 6 brakes in under an hour with the brake bleeder. Wonderful tool to have around for this! So, now I have nice, reliable brakes again.
