I'm with Welding Man, for setting up slacks on air brakes.

Hello,
You are both correct!
Now the other part of the challenge.
Are the tools used for the setup of drum brakes or disk brakes?
Guido.

 

[Welding man]

I have personally never worked on a set of Air disc brakes, in fact I have never even seen a set. I have heard they do exist,but not in my neck of the woods. The only difference in the gauges you have and the ones I have is the little radius cut out on the big end, which would make no difference that I could tell considering you are using the holes to align the pins.

Hello welding man,
We had them at work back in the 80's. Good brakes , but very expensive, and about 1/2 the life of the drum brakes. But they were ligther so we could carry more product. The setup tool were color coded.
If you look at the picture there are 2 different colors.
Both are for drum brakes, one is for tractors and the other is for trailers.
Disk brakes had a yellow setup tool.
Here is the other side of the tool. :arrow:

Hello welding man,
Here iations the picture of the other side of the
tools. Eavh application requires A DIFFERENT SETUP, that is why the different tools.
Clamping force required is differentfor each application. Disk brakes require more clamping force.

The other guys hit the nail on the head. I"ve got at least two or three of them in my toolbox left over from putting automatic slacks on a Peterbilt for Franklin Equipment Co. back in 1989/90. The guides direct you to the right position/length for the brake chamber pushrod and the clevis pin positions in order to work most efficiently. Automatic slacks were a new thing back then and mighty expensive. Franklin Equipment at that time had trucks that ran coast to coast and couldn"t afford to pay every Tom, Dick and Harry to adjust brakes on the road for them . They worked out well and nowadays they"re standard equipment on all new trucks with air brakes. I"m surprised sometimes when I go up under a truck/trailer and find old manual adjusters on it!! Then I look at the unit and its an old vehicle. Main thing with the auto adjusters is to keep them lubed regularly.

Hello Phil9N3667,
We had some trouble with them adjusting.
The units auto adjust would advance 1/8 of a in. but more often then not, the combined wear on the clevises and the rest of the pins, would be more then that.
The units then would not adjust. They have since improved on the materials, now they are the norm, as you said. Manual adjusters is now old school.
