Hi Steven,

The wheel cylinder on the Hydraulic Trailer Brake Kit # AKUBRK-35 you purchased uses the standard 3/8" x 24 threads per inch brake line fitting. The Kodiak Hydraulic Brake Hose # BH-3MFS-1-5 is one example that will work with the brake assembly you purchased, but it connects to a 3/16" brake line. So the correct brake line or fitting will depend on the size of the line you are working with.

Are you using the standard 3/16" brake line?
