Video Transcript for Redline Trailer Brakes 185150 Review

Today we're going to take a look at the Hayes/AL-KO 12-inch right hand electric trailer brake assembly for 6,000 and 7,000-pound axles. Now, electric brakes are easier to install. They offer more user control than hydraulic brakes. Basically they require only an electric brake controller which we do sell separately on our website. There is no actuator hydraulic lines necessary with electric brakes. Now, this brake assembly is a 12-inch by 2-inch passenger side electric trailer brake assembly and it's the right-hand passenger side.

The reason you can tell that . Now, on a new assembly there'll be a sticker usually that will designate right or left-hand side but if there's no sticker on it the easiest way to tell is just look at the length of the pad on the shoe. You can see the pad on this one goes here to here. On this one just goes here to here. This is a shorter pad. The shorter pad is the primary shoe.

That will always face the front of the trailer so if you put it that way, facing the front, that will tell you that this is the right-hand passenger side assembly. Now, this is a manual adjustment brake. You can see the adjustment gear right down here so it does require a periodic manual adjustment. If you'll notice on the backing plate, they do have the rubber adjuster plugs included. These will cover the access holes.

Those hole are what you'll use to put your screwdriver or brake adjustment tool through to make your brake adjustment. They do include these rubber plugs to help keep any dirt and grime out of the brake assembly. A few specs on this. The dimension is 12 inches by 2 inches and what that's measuring is the 12 inches of diameter, which is measured this shoe all the way across to that shoe. If we put a ruler on it, there's your 12 inches. The 2 inches is the width of the pad on the shoe.

If we measure the width of the pad, you can see there's your 2 inches, so 12 inches by 2 inches. Now, this uses a mounting flange bolt pattern with five bolts, right here you can see. Now, the mounting hardware you can see is included. It comes with the bolts and the nuts to install this on your axle. This assembly is designed to be used with wheel sizes 15 inches and larger and again, it's for axle rated at 6,000 pounds or 7,000 pounds. It does use 12 inch drums. Now, one last thing I do want to mention because it's electric brakes. You see the two wires in the back, the two green wires, they do need to be connected. Basically one goes to a good clean ground. The other goes to a brake feed for power and because they're both green wires, you can use either wire for either function. That should do it for the review on the Hayes/AL-KO 12-inch right hand electric trailer brake assembly for 6,000 pound and 7,000-pound axles.

  • Capacity of Trailer Hub Stamped Al KO 7,200
    That certainly looks like an Al Ko 7,200 lb axle hub/drum. With that in mind you should check the plate on the trailer that has the VIN as well as that will tell you the trailer's overall capacities as well.

  • Brake Assembly Replacement Recommendation for Al-KO 7k Trailer Axles
    Are the brake assemblies 12 inches in diameter and have 5 bolt that secure it to the mounting flange? If so, this is what you need. For a 7,000 lb AL-KO axle you would want a Hayes/AL-KO brake assembly # 185150 for the right side and a Hayes/AL-KO Brake assembly part # 185100 for the left side.

  • 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.

  • 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...

  • Ways to Identify Axle Capacity of a Trailer
    If you check the plate of the trailer that has the VIN and weight ratings for the trailer there should be axle ratings listed as well. This plate is often near the coupler of the trailer on the frame. Typically you can tell the capacity of a trailer axle by the diameter of it. Typical Axle Diameters Based on Axle Capacity - 1,000-lb - 2,000-lb Axles: 1-1/2 inch - 1-3/4 inch diameter - 3,500-lb Axles: 2-3/8 inch diameter - 6,000-lb - 7,200-lb Axles: 3 inch diameter - 8,000-lb...

  • Weight Capacity of Hayes/AL-KO 12
    The Hayes/AL-KO 12" x 2" Electric Brake Assembly has a weight capacity of 7,000 pounds per pair. For left hand brake assembly you will need part # 185100 and for right hand assembly, part # 185150. I have included a video for you to check out.

  • Which Wire of Trailer Brake Assemblies is Ground and Power
    Trailer brake assembly wiring isn't polarity sensitive. That means either wire can be the power wire as long as the other is grounded.

  • 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.

  • Are Replacement Hubs And Drums Required When Replacing Brakes On Older Trailer
    The Hayes/AL-KO Electric Brake Assembly, part # 185100 is designed to replace Kelsey Hayes brake assemblies with 5-bolt mounting pattern, and is used with a 12 inch hub/drum. The # 185100 is used on the left side of the trailer. For the right hand side you need part # 185150. We do not offer any 12 x 2 brakes for 7,000-lb axles that work with a 4-bolt brake mounting flange. The capacity for these brakes is 7,000 lbs for the pair. As far as the drums and hubs are concerned, you will...

  • Selecting 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 and bearings ride). It is possible to measure the spindles to obtain grease seal dimensions (location B on the photo) but this process requires care and a precision digital caliper like # PTW80157. You will also need to confirm the diameter of your wheel studs. We already know your brakes...

  • 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...

  • 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...

  • Do Hub/Drums Need to be Replaced When Assemblies Get Replaced
    If you hub/drums are in good shape still you don't have to replace them actually. In the question you mentioned from Aaron he ended up needing Hayes Al-KO Electric Brake assemblies # 185100 for the left side, and # 185150 for the right side.

  • Recommended Drums For Hayes Axle On 1983 Carriage Conestoga Fifth Wheel Trailer
    There are a couple things going on you can check. First, your shoes may be adjusted out too far and that is what is causing the fit issue with the drum. You will want to adjust the brakes so that they are not expanded as much and see if that helps. If you are going to replace the drums you will need to know the bearing and seal sizes that fit your spindles. I have attached a photo that shows where the numbers can be found on your old bearing and seal and make sure they are a match with...

  • What is the Size of the Center Hole for AL-KO 12 x 2 Inch 9-Hole Electric Brake Assembly
    I went out to the warehouse and pulled brake assembly # 185100 to measure the center hole for you. I used a set of digital calipers and came up with 3.24 inches so just a hair under 3-1/4 inches. The matching right hand side assembly is # 185150.

  • Replacement 12 inch by 2 inch AL KO Brake Assemblies
    Thanks for the picture. I was able to determine that you have Al Ko 12x2 inch brake assemblies. For the left hand side you would need the part # 185100 and for the right hand side part # 185150. AL KO assemblies use a slightly different bolt pattern so you have to stick with ones that are made specifically for them.

  • 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...

  • Will Dexter Electric Trailer Brake Assembly # 23-105 Bolt Up to AL-KO 5-Hole Brake Flange
    While the bolt pattern may fit, the Dexter brake assemblies will not fit properly in place of your Hayes/AL-KO brake assemblies due to differences in the designs of the assemblies backing plates. To replace your existing 12 inch x 2 inch brake assemblies on your AL-KO axle, you will want to use the Hayes/AL-KO 12 x 2 Electric Brake Assemblies, left hand # 185100 and right hand # 185150.

These are the exact same as the parts you are looking for. These are 12 inch by 2 inch assemblies with a 7,000 lb capacity. However the parts you mentioned would actually be better and at a better price. The etrailer.com parts you mentioned of # AKEBRK-7L-SA and # AKEBRK-7R-SA will not fit properly on your AL-KO axle.

These are 12 inch by 2 inch electric brake assemblies that will mount to the standard 5-bolt pattern brake mounting flanges.

These part numbers will be stamped into the metal of the bearings and most likely in the rubber of the grease seal. This will...
