Comparing Different Hydraulic Trailer Brakes for Boat Trailer
Question:
Im working on my 2 axle boat trailer with 10 inch hydraulic brakes. Id like to get the full assembly for both sides. On your site I see the AKFBBRK-35, another AKUBRK-35-D, and another 40716-15. This trailer holds a 22 foot fiberglass boat. My question is will all of these work.... is there one you recommend of the others? Thanks!

Essentially yes, all of them will work for your trailer assuming you have 3,500 pound axles and a 4 bolt mounting flange. However, there are some differences between the brake assemblies you mentioned.
The # AKFBBRK-35 are free-backing brakes, meaning they will not engage when reversing with your trailer. If your trailer has a reverse lockout on it then this feature is not necessary. They're coated with an e-coat used for corrosion resistance.
The Demco brakes # 40716-15 are galvanized which will help resist corrosion better than the e-coat. The springs are also stainless steel and the cylinders are zinc-plated. It does include the free-backing as well like the etrailer brakes.
The Demco brakes don't include any hardware. For hardware use nuts # 6-17, bolts # 7-75, and lockwashers # 5-8.
The etrailer.com brake assemblies # AKUBRK-35-D are coated in Dacromet which is great for marine applications for resisting corrosion. Also, the springs are stainless steel and the hydraulic cylinders are aluminum. However, these do not have the free-backing feature. For the same brakes that do use # AKFBBRK-35-D.
All of the etrailer.com brakes include the mounting bolts. For the nuts and washers you can use # BRKH10B.
