How to Measure to Determine the Size Trailer Brakes Needed For Hydraulic Drum Replacement
Updated 08/18/2020 | Published 05/14/2017
Question:
Where does the measurement come from to determine if I have 2-1/4 or 2-1/2inch brakes? I need to replace the brakes on a Road King boat trailer with 3700# axles. It seems the wheel cylinder is blown out and rather than buying piece parts you kits seem to be the best option.

Helpful Expert Reply:
To determine the size of the brake assemblies you need you have to measure the depth and width of the hub drum on the axle like what you see in the picture I attached. The most common size is 2-1/4 inch wide like the # T4071600-500 that you referenced.
