I lost the directions to my MittyVac II brake vacuum bleeder tool. I used it so long ago I don't remember how to use it. Anyone have the instructions on how to use this thing? I use to do it the old school way fo having someone pedal push and me craking the bleeder screw. I guess I could buy some beer and get a friend down here to help?

Thanks

 

Is it a hand driven vacuum pump?

 

ya, I remember hooking it up to the bleeder screw. BUt I don't remember the exact process for using it.

 

There should be two hoses, the hand pump and a fluid jar of some kind that the two hoses hook up to. The long hose goes between the pump and the jar, the short hose between the jar and the bleeder valve. Make sure the master cylinder is full. Hook the pump up to one of the wheels, draw a small vacuum, crack the valve and draw more vacuum. Fluid will be drawn into the jar. You shouldn't need much (unless you're purging the system ... then you've got a LOT of pumping to do). Close the valve ... done.

 

Thanks.

I have all the bits to the pump, hoses, tips, and the jar.

I replaced the master cylinder, so hopefully I don't have that much bleeding to do.


The last timei used it I replaced the rear axle on my $300 truck and had half the brake lines empty and needed to pull all the air out of that.

 

I think you've actually got a TON of bleeding to do. You're supposed to build some lines that come out of the side of the master cylinder that then run up to dump into the open resevoir. Pumping the pedal will then bleed the MC itself. You might get away with then just hooking up the lines to the system.

 

I bench bled the MC before installing it. This fills the body of the MC with fluid, and the where the lines connect were plugged. My only fear is that I took my time connecting each line so air probably got in then.

 

I'd check a manual but I am pretty sure that you have to hold open the metering/proportioning valve to bleed the rears. Pressure bleeding is the way to go. You don't have to worry about that bench bleeding crap. There's a specific procedure to bleeding on the Rams.

Good luck.

 

Hey ... road test it ... the only person you need to satisfy is you. If you like the pedal ... be happy. If not ... you've got ... um ... quite a bit of bleeding to do. Maybe you can most of out through the left front. [8D]

 

Thanks guys.

I followed the directions for bench bleeding that the manufacturer provided and the ones in the haynes manual. The pedal is pretty good right now, I just want something better. If I don't feel safe then I can have a shop power bleed them, I did that when I swapped the axle out on my beater.
