Wait does that mean my truck WAS an m925 but no longer one? The plates say m923.

Thanks artisan i have been reading those manuals for the past few hours and have now figured out how to take the pods off. It even showed me how to rebuild the service chambers but not the spring brake chambers. I will probably end up rebuilding the service chamber and the taking the spring...

Success i found the leaks. Yeah unfortunatly more than one but I finally found them after crawling under the truck for an hour. Ok so I took the white line off the chambers like you guys told me to do and felt if there was any air coming out of the chamber. I started at the back of the truck and...

Thanks those files are exactly what i need.

I tried downloading the p2p file but on both my computers were unable to read the file. Anybody have a different format of the file that may work with my computers? Also when the truck is building pressure and the compressor is turning isnt there a pressure valve that releases pressure when the...

Doesnt the larger one have spring brakes as well as a service chamber as well. In other words dosnt the larger one have two chambers, 1 for service and one for spring brake which would be the emergency brake if you lost all pressure in the system. So how do I tell which one it is? If the larger...

Ok so as you guys suggested, i hooked up a quick disconnect air coupling to the truck. I then air up the beast (after blocking the wheels) and had a buddy of mine push the brakes while i listened around and crawled around the truck. I found 1 very obvious leak in a airline on the front left tire...

I will try that when iam diagnosing the place where it is leaking, i didnt think of that. Anyone know where to get a whole new chamber for the 5 ton rockwells? If the diaphragm is bad i dont want to try to rebuild it, that would be suicide. Or should i just take the chamber off and take it to a...

I am rigourously studying all the paper work for the airbrakes and i am getting a much better understanding of the operation. I am almost certain it is a diaphragm I just need to get under it and figure out which one. Also "Artisan" i appreciate the input you have given, so please keep posting.

Yeah I accidentally hit the six instead of the nine but I am actually elligible for a cdl.

Like I told everyone I am planning on getting a cdl. I have literally driven this truck 3 times because I know there is an issue with the brakes I am just trying to resolve this problem. I am trying to learn as fast as I can about every system on it including its AIRBRAKE system. Also...

Thanks i found the file now lets just hope i can understand it.

Thanks for the input and i am planning on getting my cdl and air brake certification hopefully being 16 wont be a problem. Right now I am just trying to resolve this problem that it is having, I am used to tractors and cars not military trucks so i am working on the understanding of this big...

Ok i went and checked the gladhand and it was closed, no air leaking there when i pushed the brake. I figured out when i push the brake and hold it, the air being released is coming out of the air intake tube at a constant speed. So i think that cancels out the idea of the brake pod. I am...

Thanks i will check that in the morning. If its not that what else could it be?

Yeah i checked that but wouldnt that mean it couldnt build air at all if the gladhand valve was open? Also is there a central gladhand shutoff valve if so where? I know there are four different gladhands on the truck, one at each corner of the truck. Is there a master valve for the gladhands?

Hi, i am new to the forum and new to the military truck world. A few weeks ago i got a m923a1 truck and it works fine and drives around like it should but whenever i am at a stoplight waiting for the light to turn green the air pressure starts dropping fairly rapidly. It only happens when i have...
