Looks like I may have a problem here. What is this supposed to be connected to? this is in the engine bay next to the firewall and next to the air filter. It is spewing air and brake fluid out whenever the brake pedal is pressed.

and just out of curiosity, since I have used the pedal pushing method to bleed these brakes twice and still seem to have air in the lines, did you use the pedal pressing method or a brake bleeder on your 1987-1988 air force Deuce?

I would really like more info on bleeding the residual pressure valves that are built into the master cylinder on my type of dual circuit A2 system. Is there anything available? I didn't see anything on it in the TM you referenced. Did I miss it?

thank you. My brakes were not stopping the truck well at all so I thought I would rebuild the air packs.

Is there a TM for the brakes on my truck? How do I order a replacement Master cylinder? is it the same master cylinder and rebuild kit? I have rebuilt the air packs Bled the brakes. Still not acceptable stopping ability. Advice and suggestions for getting these brakes squared away are...

That is really weird because all my paperwork says its a 68 or 69. It still has the numbers on the bumper, should I look up that? Anyone know how to do that?

Now I am unsure how many master cylinders there are.

Since I have a dual system from the Air packs down, what is the correct bleed pattern? My guess would be to bleed the Air pack on the left then the rear left cylinder, then the middle left cylinder and then the front left cylinder with the same idea on the right from back to front after the air...

It sounds like it might be easier to just have the truck running, let the air packs assist and have someone pump the breaks while I open and close the bleed valves, is that an acceptable approach or will I break the brakes?

yep, just added pics above. thanks.

with that type of master cylinder, what is the best method for plugging my pressure bleeder into it?

QUOTE=theeDIZ;1785039]If what's in there Isnt dot 5 you don't want to mix them. And two air tanks or two booster packs ? I have two air tanks and two air booster packs. I believe the yellow is also dot 5, just not sure if I can mix dot 5 of one type with dot 5 of another type

Yes, you're correct rustystud. I have one master cylinder and 2 air packs. I am thinking that means it is a dual system after the master cylinder? I ordered rebuild kits for the air packs and have walked through the rebuild procedure. That was an interesting process. One thing that seems...

Are those rebuild kits available from boyce also? or is there another source with a better price currently?

Thanks for the feedback. I originally posted the wrong amount. I wasn't thinking clearly on it. Thanks for straightening me out there. I will just live with the 288. The main issue still is that the m185 has a different pedal adjustment and two sets of brake masters. I haven't examined it...

Apologies for asking these questions that must be answered on this site. I just can't find what I need. 1. Which TM shows the proper maintenance and adjustment for the different brake system for an M185A3 1969? I tried to look at the normal M35A2 or M109A3 and the brakes and adjustments seem...

I just did it. it is pretty cool.

ah, thanks.

huh?
