m211 brake system

We have recently bought a m211 and have brake problems. It seems the air pack has quit working. I dont know much about these brakes can anyone help?

You might look in the TM section of the SS site for the manual for the M211. The air pack is probably rebuildable. I have one out of a M135, unknown condition, if you need parts. The brake system is similar to the M35 series trucks. I never really dug into the brakes when I had my M211, so can't help much there. Good luck.

We have a TM and it really dosent say much about that. Someone said there is another manual just for the brake booster but i'm not sure. I also looked at a m35 and its close but not the same.

My dad has a M135 and the guy that restored the truck just took the booster out and it stops fine but if your going to use it to haul with you need that booster. My dad uses his for parade use only.

RE: TM 9-1827B BRAKE MANUAL

You use to be able to get a rebuilt airpack from menphis equipment. I'm not sure what it will cost now though. I got mine like 10 years ago. Take your time and go through the brake system. Fix and replace any bad wheel cylinders and any adjusters. Repack your bearings and you should be good to go. I loved the brakes on the 211/135 they stop on a dime and give 8 cents change. You will notice a big difference once you get it working. Don't let anyone fool you into thinking the air pack off a M35 will work..it will not.

I have already been told to take one off of an M35 but it is totally different. Is there anything you can do to the airpack or do you have to rebuild it?

You can check it to make sure it's clean....clear out any mud wasp nests etc. There is a diaphram in the large cylinder that moves when the air is applied to it. This pushes the slave cylinder which in turns pushes the brake fluid through the system. i.e. power brakes. If that diaphram has gone bad you need to rebuild. But for me it was easier to pull the old one and give it as a core for the rebuilt one. Make sure your getting air to the pack too.

Ill try that. I know its getting air so we should be ok there.

Did you ever get this fixed? I tore apart the M135 this week, if you still need an air pak I have a takeout one, looks newer, but still unknown condition. PM me if interested.

Hey if tjmilitart dosen`t claim the m135 air pack I will take it off your hands..........Let me know.... Tim

No still didn't get it fixed. I did however get a take off to try and rebuild but haven't got the kit yet.

I would bet theres alot of corrosion and dirt in there.

Why do we have TWO same exact threads, by two different people, this realy healps search
