air pac ?

[2ndamndmnt]

hope these pics posted. dont know how to make them fancy red circles around things in pictures so bear w/ me please. found my brake light problem to be that the air line in the pic was not connected so i didnt have enough pressure to the switch to activate it. (good part) trouble is when i hook the line up and the lights work then my brakes are locked up solid.(bad part) does anyone know why this would be?

Airpak not venting = valve problem or blocked vent line.

would lubricating the pac free up the valve?

If that's the problem, probably not at this stage, if the valve(s) are stuck, you will have to rebuild it.

Rebuilding is quite easy, but for one part. Follow the TM. Clean everything.

The gasket for the piston end cap is too small. Soak it for several days in the brake fluid and squeeze it into place. It should work fine after.

I posted some pics a while back. I think the easy thing is to get a brake cylinder hone from the auto supply for the hydraulic cylinder.

You may have the short cylinder version. So a rebuild kit probably will have to be bought at Memphis.

Is this a dual circuit system?

do not know, how can i tell at a glance?

2 airpacks or 1? Is this one under the driver's seat?

If your data plate indicates it is a M35a2C it will have dual air packs.

fogive my ignorance please, there is only one airpac (pic) and it is on the drivers side. thank you.

Not all M35A2C's have dual air packs, just the mid to late '80 Air Force truck's. And all the M35A3.

I know.
