I'm not sure I'll be much help since mine practically bled itself.

I left the rear end of the Bronco up on blocks because the air
bubble release hole is at the very rear of the master cylinder.

Fluid poured out of my open bleeder after a few pumps.

The upper "fitting" is the bleeder and the lower fitting that's
still covered with its red cap from the factory, is where the
hydraulic line went on later...

Be sure you have a slight amount of play in the pushrod or
that air hole might not uncover enough to allow the air to
escape and/or not allow the master cylinder's chamber to
re-fill for the next push.

While you're at it check for lost motion in the pushrod too...

That pushrod and stud was from a 188k mile company truck.
I swapped it out with a larger brake pushrod and welded on
a new stud to match.

Since I've never had any trouble with mine that's about all
I can tell you about hydraulic clutch systems.

ps- At least this thread ain't about pin striping?

Thanks for the advice.

1} get a peice of hose & a old clear bottle to catch the fluid,attach one end of the hose to the bleeder,stick the other in the bottle.poor a lttle brake fluid in the bottle enough that the hose is submerged

2}have an assistant in the truck to work the pedal

3} fill the cylinder replace the cap,

4}crack open the bleeder then have the assistant push the pedal to the floor
& hold it there.

5}close the bleeder then release the pedal{this keeps air from being drawn back into the system in case that the hose is not submerged}

6} repeat as necessary till all air is removed.watch the bottle for air bubbles in the fluid.make sure you keep the cylinder full of fluid,if you run it dry,you will have to start all over.

Perfect!

Do this with brake systems for sure and if make sure the hose is submerged,
there is no need for a helper.

Save this as a sticky after more review and maybe a little refinement?

This method works, guys, my son taught me this one and I've used it many
times since.

Thank You Alvin....& yes if you keep the hose submerged in the fluid Bottle you can leave the bleeder open & self bleed without help,i should have added that for those who do not know...Bob
