Video Transcript for Hayes 12" x 2" Right Hand Electric Trailer Brakes Review

Show you the Hayes/AL-KO 12" x 2" Electric Brake Assemblies for the right-hand side, part number 185150. This is a 12" x 2" assembly. So measure the diameter across the shoe and there is our 12". And then we'll measure the width of the shoe and there is our 2" mark. When paired up with the assembly for the left-hand side, these brakes are good for axles rated up to 7,000 pounds. There are two mounting patterns that you can use with this assembly.

The smaller holes are for standard 5 bolt pattern. And the larger 4 holes with the two tight ones at the bottom are for the AL-KO or Hayes for bolt pattern. Also included with this assembly are a pair of flyer leads that were into the magnet that you use for your electrical connections. It doesn't matter which you use for ground and which you use for your brake feed as long as you have a good electrical connection. This is a manual adjust assembly.

So when you first install it and as the shoes wear down over time, you'll need to adjust the brakes for proper tension. To do this, you'll work (to heat) the star wheel which will expand this pin and expand the shoes to fit tight inside the hub drum assembly. The way the electric assembly works as the drum and wheel rotate around the assembly and you apply brakes inside the vehicle, this magnet will become charged and will stick to the inside of the drum. As it drags along the drum, the magnet poles on this arm which in turn opens up the brake assembly and applies brake pressure. This is an electric brake assembly, so you don't want to use it on boat or marine trailer applications.

We know that this is for the right-hand side, because we have a shorter shoe up on the front, placed in the front of the trailer, and a longer shoe placed in the rear of the trailer. And that does it for the Hayes AL-KO 12" x 2" Electric Brake Assembly for the right-hand side, part number 185150.

  • Adding Electric Drum Brakes to a Tandem Axle Trailer With Hayes Axles
  • The first thing you will want to do is determine if the axle that currently does not have brakes already has a brake mounting flange. If it does not have a brake mounting flange, you would first need to have one welded to the axle by a qualified professional. The positioning of the flange needs to be precise, so someone with experience with trailer repair should perform the installation. If a flange is needed, the mounting pattern on the new brakes will not matter as our brakes are compatibl

  • Recommendation for 12 Inch Brake Assemblies on 6,000-Lb Axle With 4-Bolt Brake Mounting Flange
  • I have the Dexter 12 x 2 RH Electric Brake Assembly, part # 23-106-09, and the Dexter 12 x 2 LH Electric Brake Assembly, part # 23-105-09. These brake assemblies are for a right side and a left side on a 6,000-lb axle. Both of these brake assemblies are for a 4-bolt brake mounting flange. The magnets will begin humming when the brakes are applied. You can check the magnets for wear before going on to test them with a meter. If the magnets show abnormal wear or if you can see the windings begi

  • Replacement Electric Drum Trailer Brakes for Hayes 12x2 Inch Brakes
  • The dimensions that you have provided match those of Hayes brake assembly # 185150. It will fit in place of your existing brakes. The braking will be more aggressive considering the capacity of the brake is for 7k axles. You can circumvent this by adjusting the brakes a little weaker than you normally would. For the matching left hand side assembly use # 185100.

  • Replacement Brake Shoes and Linings for Hayes/ALKO 12 x 2 Inch Electric Trailer Brakes
  • The K568251 shoes and lining are actually for ALKO 12-1/4 x 3-1/2 inch brake assemblies so they will not fit if yours are 12 x 2 inch brakes. From what I was able to find you should need replacement brake shoe and lining # BP04-185. This is for one wheel and it fits Hayes/ALKO 12 x 2 inch brakes. For the bearings I would just need to know the inner and outer bearing numbers stamped into the metal of the bearings. With those numbers I can determine the correct parts or kit if available.
