I am getting slower in my uptake on details.
What make, year, size truck is being referred to regarding a mix of Huck and Bendix brakes?
In at least one year (1951?) larger GM/Chevrolet-trucks did have mix of Huck and Twinplex brakes. As I dimly recall, in that year the Hucks were on the front and the other style brakes (Twinplex - a self-centering/self-actuating/self-energizing style of brakes) were on the rear?
