Need help on how to use Miller Brake Gauge MT-19 tool kit.

[MarcDeSoto]

I am getting ready to make a brake adjustment on my newly installed brakes on my 48 DeSoto bus. coupe.  I have the Miller brake gauge tool kit, but don't really understand how to set it up.  I don't have any instructions.  The sleeves or cylinders that I have are 32, 33, 41, 47, 70, 74.  I read that the 41 sleeve is for post 1938 Mopars for the rear axle.  Does anyone know what sleeve is for the front axle? Also I don't know how to set up the tools for measuring the brake drum.  I think you have to balance it on those cone shaped pieces somehow.  Does anyone have any more information?  Thanks, Marc.

Hey Marc,

I have the AMMCO 1750 Brake Gage, which allows you to measure the trueness of your drums, and adjust the Mopar brakes. Not sure if what you have functions similarly, but here you go...

And...I'll probably  catch hell for saying this..

Have you read the factory DeSoto shop manual for the best answer to your question?

Ok Dodge, here's your hell.  You know as well as I know, that the shop manual says very little about the M-19 tool.  They have pictures of it yes, but they don't say how to set it up.  I'm perplexed about how you set it up to measure the drums for example.  Bob, yes thanks for the instructions on how to use the AAMCO tool.  I do own one, but it's missing the micrometer shaft.  If I can't figure out how to use the Miller tool, maybe I could borrow your shaft.  Thanks, Marc.  My number is 951-331-1941

I talked to Rick Hartung today about the M-19 brake gauge.  We discovered that I must have the wrong brake shoes.  The two back shoes on the rear axle are supposed to be shorter than the other shoes, about 8" as opposed to 12".  But mine are the same length as the others.  I bought these shoes back in the 80s, so too late for a return.  Can you still buy these shoes from a local source like NAPA, or do I have to go to a specialized dealer?

Ok I accept the hell you have showered me with...

Thank you.

Don't forget to arc your shoes...the ones on the car.

 

[MarcDeSoto]

Can I use the shoes I have, or do I have to change those shoes on the rear axle?  The book says the rear shoe lining are supposed to only be about 8" long.  When I look at parts dealers like AB or Moparpro, they don't specify what shoes you are getting, front axle or rear axle.  Is that a mistake?  Do garages still arc brake shoes?

After talking to Rick Hartung, I think I know how to use the M-19 brake gauge now.  I found out from Rick that I use the 41 sleeve on the rear axle and the 70 sleeve on the front.  I'll see tomorrow when I try it.  Just wondering if it's OK to go against the shop manual and Parts Book and put in a 12" shoe on the rear of the rear axle brakes?  The book says it should be about 9" in the back.
