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.

Review from a similar Hayes 12" x 2" Electric Brake Assembly


Very prompt delivery. Purchased two left and two right side assemblies to re-do a 1975 Butler tandem axle equipment trailer. The axle flanges on this trailer had the weird offset 4 hole mounting pattern and these fit perfectly. If you have the 4 hole setup, you will need to remove the studs from your old backing plates and press them into these replacements. They do not come with replacement studs, the bolts they supply are for the 5 hole mounting and should not be used in the larger holes that require studs. 122465

  • Availability of Replacement 12 Inch AL-KO Electric Trailer Drum Brake Assemblies
  • The TruRyde Electric Brake Assembly, # TRBK12E01, and 02 are replacements for Dexter 12x2 brake assemblies # 23-105. These may work with your AL-KO axle but we do have Hayes/AL-KO brakes. For a left hand assembly, 12x2, use # 185100, and the right hand is # 185150.

  • Can Dexter Electric Drum Trailer Brakes Replace AL-KO Trailer Brakes
  • We actually have 12 x 2 inch electric drum brake assemblies that are replacements for the AL-KO brake assemblies. Take a look at Hayes/AL-KO 12 x 2 Electric Brake Assembly, # 185150. This is the right hand assembly. The left hand assembly is # 185100. The Nev-R-Adjust Electric Brake Assembly, # 23-459, will fit provided that the bolt hole pattern on the brake mounting flange matches your existing set up. It should have a 5 on 3-7/8 inch bolt pattern, like flange # 4-44-1, to work.

  • How to Select Correct Replacement 12 x 2 Electric Brake and Drum Assembly for 6000-lb Axle
  • The best way to identify the correct replacement components for your trailer is by using the part numbers from your current inner and outer bearings and grease seals (or a spindle measurement where the seal rides). It is possible to measure the spindles to obtain grease seal dimensions (location B on the photo) but this process is prone to error and requires a precision digital caliper. You will also need to confirm the diameter of your wheel studs. We already know your brakes are 12 x...

  • Availability of Old Round-Style Brake Magnets for Hayes 12 x 2 Electric Brakes
  • If your trailer has pre-1988 Hayes electric brakes that use the round-style magnets you will have to replace the entire brake assembly. Until a few years ago the old-style round magnets were still available as replacement parts but they are no longer offered. It will therefore be necessary to update your trailer with new brake assemblies. In your case you will also need to replace your hubs/drums in order to use these new brake assemblies. Replacement hubs/drums need to be matched based...

  • 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.

  • How to Choose the Correct Brake Assemblies and Hubs and Drums for a 7000 lb AL-KO/Hayes Axle
  • We do have replacement AL-KO/Hayes brake assemblies for 7,000 lb axles, # 185100, for left side and # 185150 for the right. These are 12 inch by 2 inch electric brake assemblies that will mount to AL-KO/Hayes 4-bolt pattern or standard 5-bolt pattern brake mounting flanges. The way to determine what hub and drum you need is to remove the old hub and find the bearing and seal part numbers. These part numbers will be stamped into the metal of the bearings and most likely in the rubber...

  • 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...

  • Replacement Brake Assemblies for 7K Axle on RV Trailer
  • According the the photo you kindly provided, you need Hayes/Al-KO 12x2 brake assemblies, part # 185100 for the left side and # 185150 for the right side. This assembly will work with an axle that has the AL-KO 4 bolt pattern or the standard 5 bolt. If you can crawl under your trailer, you should be able to see the brake mounting flange from the rear, and see how many bolts it has. I can understand your reluctance to start disassembling things until you have everything in place, but...

  • 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.

  • Brake Assembly Recommendations for a 2008 Forest River RV with 7k AL-KO Torsion Axles

  • Round Replacement Brake Magnet Recommendation for a 1988 Travalong Trailer
  • We have some older style round brake magnets that could work for you. Check out the Dexter Round Brake Magnet # BP01-140. This magnet is designed for assemblies that were made before 1988 so there's a good chance this is what you would need. Another round magnet we offer is the Trailer Brake Magnet Kit # BP01-068. The only solution for a bad brake magnet is to replace it.

  • Replacement Brake Magnet for 1980 Hayes Brakes With Recessed Back Plate and 3 1/2-Inch Center Hole
  • We do offer replacement magnets for older Hayes electric brake assemblies but none of these are suitable for brakes produced before the mid-1980s. For reference I have linked four such magnets. The good news is that we do offer complete brake assemblies that are not much more in cost than replacement magnets alone. The link provided will take you to our main page for electric drum brake assemblies where you can use the filters in the left-hand margin to narrow the results based on the...

  • Replacement 12x2 Hayes/AL-KO Brake Assembly
  • For the price of all the parts you need and the headache of finding all the compatible parts you are better off just getting new brake assemblies honestly. It'll be easier and most importantly it will be cheaper. Plus everything is new. You said you have a 12 inch by 2-1/4 inch brake assemblies which isn't a standard brake assembly size. Most likely you have a 12 inch by 2 inch assembly as that is a very common size. The correct AL-KO brake assembly would be the part # 185150. I would...

  • Availability of Compatible Electric Brakes for Old Travel Trailer with 7000-lb Axles and 6-Bolt Hubs
  • We offer several electric trailer brake assemblies for 7000-lb axles, including the Hayes # 185100 which is a left-hand unit that mates with right-hand brake assembly # 185150. These 12 x 2-inch brakes offer the flexibility to be able to mount to either 4-bolt or 5-bolt brake flanges. The link will let you see all electric brakes compatible with 7000-lb axles. If your current hubs use bolts to secure the wheels (rather than the more common lug nuts) you may be able to install screw-in...

  • Electric Trailer Brakes for Trailer w/4 Bolt Mounting Flange w/Top Bolts Further Apart then Bottom
  • If the axle on your trailer is a Hayes/ALKO axle then you will need brake assembly # 185100 for the left side and # 185150 for the right side. If it is a Dexter axle then use # 23-105-09 for the left and # 23-106-09 for the right. The 4-bolt offset mounting pattern is not very common and these are the only brake assemblies we have that will fit that pattern.

  • It sounds like you need the Hayes/AL-KO 12 x 2 Electric Brake Assembly, # 185100, (left hand) and # 185150, (right hand). I have measured the 4 hole pattern on these brakes before. The top holes are 3.09 inches on center and 2.55 inches apart on center for the bottom 2 holes. Top to bottom they are 3.40 inches apart on center. The holes can accommodate a 7/16 inch bolt size.

  • 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...
