The old brake assemblies best resembled an old style Hayes 10" brake, even though the drums said Dayton on them. Close examination of the brake shoes showed that the shoes were about 1/8" short of being fully inserted into the drums. A 1/8" ridge of unworn brakeshoe material was on the inside edge. For lack of being able to locate anything that resembled the current brakes, a set of 10" Dexter's were grabbed for comparison. The Dexter assembies were about 1/8" to 3/16" taller than the old brakes. So the Dexter's installed with the brake shoes being fully inserted into the drums unlike the old brakes. The owner of this "classic" travel trailer now has 4 brand new Dexter brakes that fit better than the old ones did. He is now one "happy camper".
