• How To Determine If Boat Trailer has 10 Inch or 12 Inch Brake Assemblies
  When determining if you need 10 inch or 12 inch brake assemblies there are a couple of easy things to check to confirm the fit for your trailer. The first thing is you can measure the diameter of your hub. The second thing is you can look at the brake flange, if it has 4 bolts then it is 10 inch if it has 5 then it is 12 inch. Because you know you have a #84 spindle we can be confident that you have a 3,500 lb axle and you will need the 10 inch assemblies. I recommend the Hydraulic...

• How to Determine Which Hydraulic Brakes to Use on a Trailer
  There are two different types of hydraulic brakes used on a trailer which are disc brakes and drum brakes. A drum brake has a small round drum in which the shoes inside the backing plate push up and out to slow the trailer whereas a disc brake assembly is composed of a circular round rotor and half moon shaped caliper which clamps down on the rotor to slow the trailer. I have attached a photo of both to give you a better understanding. The part number you provided "KH8444" was manufactured...

• Difference Between Demco 10 inch Drum Hydraulic Brakes and etrailer.com Brand Brakes
  The big differences is basically pricing and brands. The part # AKFBBRK-35-D is a pair of Dacromet coated drum, hydraulic brakes that are free-backing. The part # 40716-15 is essentially the same thing buy made by Demco. The etrailer brand is going to cost less since it's our brand and there's not as much markup so it's the better deal. Now the part # 40716-15 is basically just the part # 40716 and # 40715. What doesn't make much sense though is the pricing difference. It would seem...

• Comparing Free Backing and Duo Servo Hydraulic Brake Assemblies
  Good questions. The difference between free backing brakes like the # AKFBBRK-35-D and regular hydraulic drum brakes like # DMSB18794M-93M (referred to as duo or duel servo) is that the wheel brake cylinder has pistons on both sides of the regular/duo servo brakes instead of just the one side on the single servo free backing assemblies. The amount of braking doesn't change much between them, they just function differently yet under the same amount of hydraulic pressure. The duo servo...

• Difference Between Single, Dual and Free Backing Servo Brake Assemblies
  The biggest difference between the servo styles that you'll notice is between free backing plates and the others. The free-backing plates will allow your trailer to back up without having the brakes lock up. With surge brakes typically when you go to reverse the trailer it pressurizes the brake system which locks the wheels up. Free backing setups are designed to allow the pressure to build but not activate the shoes of the assembly so the trailer can back up. Some surge brake trailers...

• Replacement Brakes and Hubs for 1987 Moody Boat Trailer with 7 x 2-1/4 Hydraulic Brakes
  The 4-bolt mounting pattern of 7-inch brakes is the same as for 10-inch brakes; both use bolts/holes spaced apart by 2-7/8-inches on center. Moving to larger brakes will naturally require new hubs and these new hubs must use the same set of bearings and the same wheel bolt pattern as your current ones. Also note that larger brakes and drums will be compatible with different wheel diameters than your 7-inches brakes were. The free-backing 10-inch hydraulic brakes you referenced, kit #...

• Replacement Brake Assemblies and Brake Line for 3,500 Hydraulic Trailer Brakes
  Do you by chance have a 3,500 ALKO axle 8500? Or an 8,500 lb axle? I believe you'd have the 3,500 lb axle but wanted to be sure.
