There have been questions on some of the boards about basic should know air brake information. I know at one time someone had some wonderful educational material on air brakes. I have looked but can not find it again. Someone like Bendix, Haldex, Midland had it. The links below are not the detail I am trying to find again. The first and last one will give the reasons, I would like the information available to all.
Thank you for any help.

Craig,

I hope you pass that info along if you get it.  There was a class on airbrakes a while ago by Bendix and it cost dearly, as I recall.  I think somebody here conducts seminars for a profit at various bus Knut gatherings so I can easily imagine a "rice bowel" issue.  I tried some of Bendix sites but found I was unable to crack the functioning of various valves by their symbol.  Do you know where there is a legend of the symbols used in the airbrake world?

Good luck,

John

This link has a 117 page catalogue of air brake parts. Good pictures to ID your parts.

http://www.meritorhvs.com/MeritorHVS_Documents/100d1.pdf

Arvin meritor: makes many more truck parts then just air brakes, worth looking them up.

 http://www.meritorhvs.com/LODsearch.aspx?keyword=Air+Brake+Control+Valves&category_id=3&product_id=37&publication=All&page=1

Meritor wabco: look like they have stuff on air disc brakes. A google search turned up the above info.

I found this within my with one of my previous post sites. I think this might be worth looking at. I am going to try and order it, they say $25.00 for non members. They call it the industry standard for driver training.

http://cvsa.stores.yahoo.net/pracairinhan.html

This next link is practical air brake adjustment also $25.00 for non members.

http://cvsa.stores.yahoo.net/praibrad3.html


This is a sample air brake quiz. Click on the computer image to start it, not the pricing link. I was really surprised at my score not what I thought it would be!!!!!

http://www.practicalairbrakes.com/USA/usa.html

The above is the type of info I was looking for. I still have not found the internet site that has about a hundred pages of free down load. I believe it is just as good.

John,

Great time for putting in a pad/pit, can I use it?  Grin

All the brake links posted should get you more than enough information and guidance. Good reading for cold winter days/nights.

The assessment link for cvsa.org seemed to be 404, however here is a general assessment of air brake knowledge.

Zub,

The picture shown of the Flx with the LARGE hole in the front left corner belonged to the late Patrick (Poppy) Shlicht.

Cat and I worked on that bus in January of 2008 at a storage yard in lower Alabama, just across the bay from Pensacola, Fl.

We used luaun to build a temporary front and side for it, and got the engine, (427 Chevy) running again.

The problem with the brakes wasn't that they were mis-adjusted..... the problem was that the PO had installed an upgrade of spring brakes and did a really great job..... except he forgot to remove the cage bolts in the spring brake cans, so the bus only had the front brakes to stop with.

When coming up on a stopped flat bed truck, Poppy couldn't get enough brake to stop and the photo is the result of the joining of 2 motor vehicles.
He was thrown from the drivers seat to the floor, still hanging on to the steering wheel, and the drivers seat was torn from the floor and sent back about 6 feet.

I believe that bus is now in Chattanooga at Don Bowen's Garage. It has a whole new front and probably looks prettier than it has in the last 15 years.
