How To Determine The Correct Replacement Brakes For Your RV/Boat Trailer

Question:

Hi I’m looking to buy new brakes for my boat trailer but I am not sure where to begin with what parts to buy. I know it’s a calkins trailer and they seem to have gone out of business so I can’t find any info from them. If you can point me in the right direction that will help

Hi Isaac,

When replacing trailer brakes there's a few things to check to figure out the correct replacement. The first thing I start with usually is the axle capacity. If you can find the axle tag sticker on the axle tube we can use the information on it to determine the capacity. If the axle tag is gone then you can also just measure the hub/drum assembly like I have pictured below. We can then take those measurements to find the correct brake assemblies to fit the hub/drums.
