To determine which hydraulic drum brake assemblies will fit on your 2,500 pound axles you'll need to measure the dimensions of your drums.

For example, if your drums are 10 by 2-1/4 inches you can use # AKFBBRK-35-D. Since you have a boat trailer I suggest getting galvanized or dacromet brakes to resist corrosion.
