I have a Mityvac 6840 brake bleed kit that I am trying to bleed the brake system on my 2002 Ram.  None of the brake bleed adapter reservoir lid adapters in the kit work.  Has anyone used the Mityvac 6480 to bleed their brake system and if so, which brake bleed adapter did you use for this kit.  The Dodge Ram 2nd Generation is only one of the most popular pickup trucks in American automotive history........you would think they would include the brake bleed adapter for this vehicle!!!     Thanks in advance for any replies and help!  

I do something much easier. Mayo jar and a piece of vinyl tubing. Worked for years nothing fancy but it gets the job done without the price tag. 

I have a Mityvac 04000.  I attach a hose to the bleeders and suck the fluid into a sealed bottle with the vacuum pump. 

I spoke with Mityvac Tech Support this morning and they do NOT make a brake bleed adapter specifically for these trucks.  I asked them if the MVA809 which I ordered last night would work and they said most likely it would.  Figured I would post this so anyone else that purchases this bleeder can benefit.

I had been using a vacuum pump, but now have better results with a pressure bleeder, put 20 psi and run around to all the bleeder, no issue with sucking air through the threads. 

That is how this brake bleeder is supposed to work.  Just have to find the correct brake bleed reservoir adapter.  Hopefully this one is it.

The only difference between my mayo jar and this is the pressure is external to the system vs the master cylinder doing all the pressure work no difference though. Hook up the mayo jar, crack the bleeder, jump in the seat and pump the pedal. The vinyl tubing in the jar the tip is submerged in the fluid so it's not possible to draw back up the air and this can be done by a single person. 

 

Hold the bus!!!  I am not sure if this is a matter of having egg on my face or crappy tolerances in Mityvac's manufacturing.  Anyhow, I ordered a Motive Power Bleeder Model 0103 from Jegs.  Came right in the next day.  

 

So.......today I pull up the 2002 Dodge Ram 2500 FSM and go to page 5-8 and it reads the following:

STANDARD PROCEDURE - PRESSURE
BLEEDING
Use Mopar brake fluid, or an equivalent quality
fluid meeting SAE J1703-F and DOT 3 standards
only. Use fresh, clean fluid from a sealed container at
all times.
If pressure bleeding equipment will be used, the
front brake metering valve will have to be held open
to bleed the front brakes. The valve stem is located
in the forward end or top of the combination valve.
The stem must either be pressed inward, or held outward
slightly. A spring clip tool or helper is needed to
hold the valve stem in position.
Follow the manufacturers instructions carefully
when using pressure equipment. Do not exceed the
tank manufacturers pressure recommendations. Generally,
a tank pressure of 15-20 psi is sufficient for
bleeding.
Fill the bleeder tank with recommended fluid and
purge air from the tank lines before bleeding.
Do not pressure bleed without a proper master cylinder
adapter. The wrong adapter can lead to leakage,
or drawing air back into the system. Use
adapter provided with the equipment or Adapter
6921.

 

Hmmmmmm..........Adapter 6921 is peaking my curiosity (yes, I am kicking myself for not having reviewed this earlier) so I Google Adapter 6921 and the actual adapter comes up for sale on eBay for around $65 but the Mityvac MVA802 brake bleed adapter also comes up in the search.  Last time I tried it, I could not get it to properly thread onto the master cylinder reservoir.  I go the garage, get the MVA802 out yet again and AGAIN compare it to the master cylinder cap and they look really close but the tabs on the MVA802 are twice as long as the tabs on the OEM master cylinder cap.  This just pissed me off and I applied a LOT of force (way too much for what I would consider the limits of reasonable) and the damn thing just barely goes onto the master cylinder reservoir mouth.  I tried pressurizing it and it held pressure.  I'm going to use it.  The MVA 809 would work also but the one I recieved from an eBay seller was a counterfeit version or someone at Mityvac had a bad day on the production line.  The J bolt threads were incomplete and the fasteners would not thread on to them, the quick disconnect fitting was for compressed air and not the brake bleed adapter.  I requested a return and the guy told me to just keep it and refunded my money.  

 

Now I am able to pressure bleed the brake system........but wait!!!!!!  If you pressure bleed the brake system, you must follow the above procedure to bleed the front brakes which STILL requires 2 people or a special clamp!!!!!

 

At least I am making progress!  

 

 

This I believe will be helpful for anyone else doing this task.
