Brake Bleeding Lesson (The Hard Way)

[Tackettr]

When bleeding your brakes with a pressure bleeder, "Do not push down on your brake pedal!" . It appears that if you have air in your lines and the pedal goes down too far, the pressure in the reservoir will push fluid in front of the piston and out of the front of the master cylinder on the ground. I wasted a lot of fluid and went chasing the wrong problem because of this!

If you want to "feel" your brake pedal travel be sure to take the pressure off your bleeder first!

I'm sure there was Caution about this in the thread telling me how to make and use my pressure bleeder. But I missed it!

The most simple way to bleed brakes is without the pressure bleeder. We've done it various ways, the best is to drain the air tanks, install a fitting into the drain plug opening to connect your shop air hose quick coupler, set your regulator on 15PSI. Bleed the entire system the old fashioned way gently pumping the pedal & opening bleeders starting at the booster. Pour a small amount of fluid into a glass container, use a rubber hose to connect to the bleeder & submerge it in the fluid in the container so air isn't drawn back in through an open bleeder. Very simple & gives a perfect bleed out every time.

I've done it the "old fasion way" also and after doing it correctly with my pressure bleeder, I will never do it the old way again.

The pressure bleeder is nice! Just don't push your brake pedal when its pressured up!

Also, not sure why you would need air pressure on the duece? I know its "air assist" but doesn't take that much pressure just to bleed the system.

Thanks for the heads up. I just finished building a pressure bleeder to take care of the brakes on my M35A2 and I'm sure I would have made the same mistake.

Since I'm Soldier A, B, and C..... I have to use the pressure bleeder

The reason I shared this is because many deuce owners who on occaision need to bleed the system don't have pressure bleeders, we've told our customers who work with the old way this method for years, never had a complaint come back as a result. If a brake system is built correctly, bleeding isn't something that will be needed often at all, most simply aren't interested in purchasing or building a pressure set up for such occaisional use has always been the line I've heard. What ever you prefer is what you should use.

I made one of Kenny's..recovery4x4...power bleeder out of a hudson sprayer. Works better than a pressure pot!

 

[Stan]

Thanks for the input Charles. Haven't had to bleed them yet but nice to know some tricks.

mseriesrebuild,

you might want to search out the recovery4X4 pressure bleeder. it uses a garden sprayer, and costs about $12 total from lowes or home depot. i built my version of the bleeder, and had the brakes completely bled in well under 30 minutes. there is no reason to bleed the brakes anyother way unless you are broke down on the side of the road. the best part of all this was i do not have to get my always unwilling wife to "help" when i need to work on the brakes.

I have a commercial pressure bleeder that has connections for late model Fords and one for my CUCV. I made a connector to adapt it to the deuce. It is just like a bug sprayer but has a built in pressure gauge so you do not pump it up too much. You must be very careful when using a pressure bleeder and not pump it up too much.

[buccaneer]

Why?

You must be very careful when using a pressure bleeder and not pump it up too much.

Why is that? cavitation of the fluid? WHat if I'm using DOT3/4?

Thanks?

IIRC, your exposing the secondary seal to pressure. It's not intended for high pressure. Only the primary seal is.

 

[buccaneer]

OKay, I'll take your word on it as I don't know anything about a secondary seal...

I agree!!

Do you have some info on this assembly? Pictures, schematic, parts list?

So what is too much? I have been using mine @ 15 psi.

i use about 15 psi on mine when i do the 819
