[AT] Now Ralph Video -- disc brakes

[Jim & Lyn Evans]

Older LA cases had drum brakes on the axles.  Some were mechanical, most 
were hydraulic actuated with a master cylinder.    I don't think any 
worked very well.   My 52 LA has dual disk brakes on a countershaft.   
It actually stops fairly well by Case terms. (Cases were made to go, not 
stop)  This would be the same type of brakes used in all the Case 
tractors from 52- 67 or so.
