Video Transcript for Dexter Axle Trailer Brakes - Disc Brakes - K71-638-639 Review

Speaker 1: Today, we're gonna take a look at the Dexter E-Coat Disc Brake Kit, 12" Rotor and Hub with the 6 on 5 1/2" Bolt Pattern for 6000 Pound Axles. Now, this trailer brake assembly will make it easy to upgrade from your drum brakes to your disc brakes for better performance. Gives you more consistent stopping even at highway speeds and dramatically shorter stopping distance, and it is easier and less expensive to maintain.All these parts have a nice E-Coat finish to them to provide corrosion resistance for freshwater and limited salt water use. Now, this kit will include everything shown here on the table. It is two full brake assemblies for one axles. Comes with the two E-Coated rotors, the two E-Coated hubs with the bolt's studs already pressed in, the two E-Coated ductile iron calipers with the four semi-metallic brake pads, also the two E-Coated caliper mounting brackets with the bolts and nuts to install it, and if you notice all the bearings and the hardware to install everything is also included.Now, the rotors on this, they are a vented rotor which will help regulate temperature, prevent overheating.

It'll dissipate the heat. Also included are these hubs which will replace your existing hubs, and the calipers are a self-adjusting caliper to ensure maximum surface control for nice, smooth, equal braking. They do include the semi-metallic brake pads to help resist heat and provide excellent grip.The mounting brackets that they install to, they are also a ductile iron mounting bracket. Prevents strength and durability. Again, all the hardware's included.

Also what's nice is the grease caps they give you are easy lube grease caps which feature the removable center rubber plugs, so when these are installed, you can just pop out that rubber plug, gain access to the grease zerk fitting that's on the end of an easy lube back, so pump your grease in there and there's no need to remove the hubs.Now, this kit does require a hydraulic brake actuator and brake lines that are to install these to activate the brakes, and those are sold separately on our website, and they're usually listed on this product page as a related product. You do want to make sure when you do get the actuator or the brake lines that they do have to have at least a 1600 PSI rating. These parts are made in the USA.Again, they are designed to fit axle capacity of 6000 pounds. The wheel size that'll work on these hubs are 15", 16", and 16 1/2". The bolt pattern is 6 on 5 1/2" bolt pattern.

The wheel bolt or wheel lug diameter is half an inch the rotor diameter is a 12" rotor diameter. On the mounting brackets, they are a five bolt brake flange configuration, and then all the bearings, races, and seals are all included, all laid out here. The bearings, which are included, you have your inner bearing which is the larger bearing. That's part number 25580, has a 1.75 inner diameter. The outer bearing, which is a smaller, is part number 15123, has a 1.25" inner diameter.Now, the bearing races, they already pre-install them onto the hub.

The grease seals, they are a part number GS-2250DL. They are a double lip grease seal, have an inner diameter of 2.25" and an outer diameter of 3.376". That should do it for the review on the Dexter E-Coat Disc Brake Kit, 12" Rotor and Hub with the 6 on 5 1/2" Bolt Pattern for 6000 Pound Axles.

Ask the Experts about this Dexter Axle Trailer Brakes


  • 6,000 lb Disc Brake Kit with 6 Lug Bolt Pattern for Converting Raptor Toy Hauler to Disc Brakes
  • The bearing difference doesn't mean too much since the spindles are the same so regardless of which axle you decide to put the brake kit on you'll need a 6k rated disc brake kit with an 6 lug bolt pattern. So for that we have the Kodiak brake kit part # K2HR526D which is a fit for your spindles. This kit does require the bearings part number # 25580 and # 15123 and seal part # RG06-070 which are sold separately. Or if instead you were wanting a kit that uses an idler hub and a slip-on...
