Deuce Brakes

[Elk1111]

I have a friend stuck in Pecos Texas with a hard brake pedal and the rear brakes smoking. Any ideas how to do a roadside repair to get him rolling again.

Maybe open service side of air just a hair, to let vent.

Take the hotttest drum and disconnect the hydraulic line and plug it.

I had someone put tacks or small nails to seal off one of mine before. Head was perfect size to seal the line. Wondered why brakes wouldn't work.

I had him back off the brake shoes a bit and let it cool down. Pedal is back to normal. He’s rolling again and will stop every 25-50 miles to reassess. He’s got 225 miles to go.
Does anyone know how much a bobbed deuce weighs in case we have to trailer it?

approx 10,500, thats what mine weighs

Thank you. He’s almost home with no more problems. We’ll flush everything out and inspect everything when he gets here.

Bleed hole in master cylinder (small hole to the rear, at the bottom) clogged or sticky airpack! My 5 cents.

I knew I seen that before
Get the proper fittings and wrenches and kroil
That was my How to get home post.

And, IIRC, if the Master Cylinder rod doesn't have enough free play travel, then it can't vent the pressure when the brakes are released, through that little hole, back into the reservoir.

Bleed out some of the brake fluid, then follow the advice's posted by others.

That little hole is called a compensating port if anyone really needs to know.

This is exactly what happened with my m818, I had replaced the MC and the rod was just a tad too long... kept having to stop and open a bleed screw. Thought I got trash in the MC or air pack. Adjusted rod and was smooth sailing.

A bobbed deuce. Unless an A3, it has 1 3/8" cups in the wheel cylinders. The A3 uses a 1 1/2" cylinder on the front and has1 3/8" on the back.

Thing is, the 11/2" wheel cylinders will fit with a small rod length modification on both front and back on the deuce and since the back axle is removed, even the stock system single circuit, can deliver about 20% more force. The volume of fluid on 6 wheels with 1 3/8" is about equal to 4 wheels with 1 1/2"

With everyone going to even bigger singles than the 14.5 on the A3, there is a need for more braking force so please consider using the 1 1/2 like the A3 front allthe way around your bob deuce

One way or another Me thinks they been home long time now.
