My grandparents owned a couple of 34 Chevy trucks, dual rear wheel rigs set up as tractor-trailers to haul beer from St. Louis and Milwaukee back to Nashville. Mechanical brakes on the trucks, and NO brakes on the trailers. Eventually, Grandpa converted both trucks to vacuum-boosted mechanical brakes! Still had no way to brake the trailers!
