Video Transcript for Redline Trailer Brakes BP01-180 Review

Today, we're going to take a look at the replacement trailer brake magnet for the Dexter, Alko, and Hayes 12" electric trailer brakes, this part includes everything shown here on the table, the magnet itself, the spring, and the clip to hold the magnet into place. This magnet kit will allow you to replace the worn-out magnet on your 12" trailer brakes, and because you're replacing just the magnet, not the whole assembly, it will save you time and money. This part is designed to work with the following brake assemblies, it'll work with the Dexter 12" x 2" on a 6000 pound axle, the Alko 12" x 2" on the 6000 and 700 pounds axles, the after-1988, and the Hayes 12" x 2" 600 and 7000 pound axles after 1988. If you notice, the magnet is an oval design, and they do that to increase the efficiency of the magnet, and to also extend the life of the magnet. Just to give you an idea of the size on this, the width of it you can see is about 3 1/8", and the height going to be right at about 2". You also notice, when the wires come out of the magnet, they have a section of a protective sleeve over that, and the reason they do that is because, when this is installed in your brake assembly, that initial part of the wire is what goes through the backing plate, so you don't want the wires rubbing up against the backing plate and causing problems, so they put this nice, protective sleeve on here to protect the wires from getting damaged. Also, if you notice, it has the two wires, two black wires coming out of it. It doesn't matter which wire from the magnet is attached to the power or the ground, you just want to make sure that one of the wires is properly grounded, and then the other wire will be attached to your electric brake output circuit from your trailer connector.

That should do it for the review of the replacement trailer brake magnet for the Dexter, Alko, and Hayes 12" electric trailer brakes.

by:

My trailer is very old. It is home built and the brake plates were welded on the axles and I had to turn the axles around to get the brake actuators to function in the proper manner. While I was working on it, I realized the magnets needed replacing, but the originals were of a brand I couldn't find. I managed to measure the old parts and found the correct replacement on etrailer.com at less then half the price a local trailer shop wanted for a similar part. The magnets were exactly the right part, they arrived a day sooner then I expected and the brakes are back together and functioning as advertised. Now if it would stop raining I could get the axles back under the trailer and get the brakes wired up again. I'm not complaining about the rain, and certainly am happy about the parts and quick service. 142136


Comments
Thanks for checking back with me as I had completely forgotten the trailer brake issues I had last year. The brakes are still functioning fine and we are now using that trailer to haul logs and equipment on a regular basis with absolutely no problems with the brakes. I wish I had reworked them earlier and would recommend the parts I used to anyone with a similar issue.

  • Troubleshooting Electric Brakes That Energize When Not Connected to Tow Vehicle
    Trailer electric drum brakes do make a humming sound when their magnets are energized with power from a trailer brake controller. This is normal behavior and it is usually possible to hear the energized brakes from about a foot away. If your brakes are being energized when the trailer is NOT connected to the tow vehicle this indicates an issue in the trailer wiring. Something is allowing 12V power to reach your brakes when it should not. Since the trailer is disconnected from the tow...

  • Troubleshooting Trailer Brake Magnets With Wires Cut Short and Inside of Brake Assembly
    If the wires are cut to short and are inside the assembly, you can make the connections inside using the Deka Heat Shrink Butt Connector - 12-10 Gauge - Nylon Insulation - Yellow - Qty 5 # DW05745-5 to ensure a good connection. If you don't have enough movement behind the brake magnet spring assembly for the connections, then I recommend replacing the magnets so you will have appropriate function. For 10 inch assemblies use # AKBRKR-M10 or for 12 inch assemblies use # AKBRKR-M12 or #...

  • 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.

  • 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...

  • Would Installing Higher Rated Brake Magnets Increase Braking Power
    The magnets of a brake assembly do not actually give the brakes more or less power. You want to use the correct magnets for the assemblies you have on your trailer. Going with a magnet for a higher rated assembly will simply make the brake activation harder to control. They won't be any more powerful but they will be more touchy when adjusting the braking power. I would check the main ground for the trailer. This is the wire that runs from the trailer connector to the trailer frame and...

  • Can 3500 lb AL KO Brake Assemblies be Replaced with Dexter Brake Assemblies
    Yes, the Dexter Nev-R-Adjust brakes will work with your 3,500 lb AL-KO axles. Brake assemblies attach to the brake mounting flange that is welded to the axle or spindle. The brake mounting flange on the 3,500 lb AL-KO axles uses a standard 4-bolt pattern that is compatible with AL-KO 3,500 lb brake assemblies and Dexter brake assemblies. For the left hand brake assembly, you can use part # 23-468 and for the right hand use part # 23-469. I have attached a review video for the Nev-R-Adjust...

  • How to Wire Trailer Brake Magnets
    As long as one of the wires coming from the back of the hub is a ground and the other is a power, it does not matter which wire on the magnet goes to which wire from the back of the hub. I have included a link to a video of a magnetic brake replacement video that may be helpful. It is for a different size brake, but you it shows the whole process.

  • Troubleshooting One Brake Locked Up on Trailer
    Sounds like there could be a short in your trailer wiring for one of the brakes or there could have been a mechanical failure in that one brake assembly. The second possibility is more likely since only one brake was affected. First inspect the wiring to the affected brake (and the others too) to check for signs of damaged wires or worn insulation that could cause a short. If the short was near the one brake assembly then that might cause the issue to be isolated to the one brake. Also...

  • Are Trailer Brakes Always On or Off When Not Connected to a Tow Vehicle
    Unless something is putting voltage on the brake output circuit of the trailer wiring the brakes of the trailer wouldn't be activated. So if your trailer wasn't plugged into a tow vehicle the trailer's brakes should not be activated unless the off-chance the breakaway system's pin has been pulled. I attached an FAQ on breakaway systems for you to check out as well as an FAQ on brake controllers that you may find helpful.

  • 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...

  • Electric Trailer Brakes Lock Up When Trailer is Plugged in to Tow Vehicle
    The easiest first step here would be to try the trailer on a different truck, and see if the same problem occurs. If the trailer brakes are free until the trailer is plugged in, I suspect that something is mis wired. I would suggest examine the wiring where the break away system was bypassed and make sure that the 12-volt accessory feed is not connected to the brake wire at some point. Are you by chance using a 7 to 6-way adapter? If so, there are two accepted ways of wiring a 6-way...

  • Old Hayes / AL-KO brakes Replacement Brake Magnets
    The Replacement Trailer Brake Magnet for 12" Brake Assemblies # BP01-180 will fit old Hayes AL-KO brake Assemblies that are 12x2 inches. They fit 6K and 7K assemblies after 1988. For the 7.2K and 8K oval you would want the Trailer Brake Magnet For Dexter 12-1/4 Brake Assembly, White Wire # BP01-265 instead.

  • Replacement Brake Magnet for 12 x 2 Inch AL-KO Electric Brakes on a 2009 Cougar 5th Wheel Trailer
    You can actually use either magnet, # BP01-180 or # AKBRKR-M12, since your trailer is well past the 1988 cutoff for AL-KO assemblies. There is no advantage of one magnet over the other so I would go with # AKBRKR-M12 since it costs less.

  • Troubleshooting Trailer Brakes that Lock Up When Trailer Wiring is Connected
    What it sounds like is happening is that the 12 volt accessory circuit on your trailer wiring is being mistakenly wired to the brake output circuit either by a short or something being miswired. I would first start at the 7-way of your truck and using a circuit tester like part # PTW2993 check for voltage in all of the correct pins. I attached a diagram for you to use as a guide. Next, you can use a jumper wire from a 12 volt car battery to apply voltage on all of the different circuits...

  • Availability of Replacement Round Magnet for Older Dexter 6,000 Pound Brakes
    I do have a solution for you, however we don't have a replacement brake magnet available that will work on your older 6,000 pound Dexter Axles. The round magnets you have pictured are pretty old models that aren't made anymore and the current oval design won't be compatible as replacements. With this in mind your best option at this point will be to replace the brake assemblies themselves. For 6,000 pound assemblies the Dexter Nev-R-Adjust Brake Kit # 23-458-459 will work great. Both...

  • How to Release Trailer Brakes After Trailer Break Away Pin Pulls Out
    If your break away switch looks like # HM20010 then you should just have to push the pin back in. This will break the circuit and release the trailer brakes. If this does not work then there is some other wiring issue going on. You will need to remove power from the system to get the brakes to release. You can do this by disconnecting the break away system battery (just remove the power wire from the positive battery terminal). After the brakes release you will want to determine the...

  • Troubleshooting An Electric Drum Trailer Brake that Will Not Release On One Side
    I would start by checking to see if 12 volt power is constantly running to the right brake. If it is for some reason, trace the wiring to make sure it is connected in the right place. Also make sure the ground is attached to a clean and corrosion free bare metal surface. Then, you can go back and basically start from scratch with the installation. Make sure that everything is properly installed and that the brakes are adjusted correctly. You can also test the magnet. I would check the...

  • Troubleshooting Trailer Brakes that Lock Up When Connector is Connected
    When we see this problem it's almost always with a 6-way trailer connector being used. The issue is that there are two ways that a 6-way is typically wired and the only difference is that the 12 volt accessory circuit and the brake output circuit are swapped. Anytime we see trailer brakes immediately locking up when connected and there's a 6-way involved this is the issue. What you need to do is swap the two circuits on the 6-way adapter or the 6-way connector and you'll be good.

  • Troubleshooting Trailer Brake Magnets that Have Voltage to Them But Arent Activating
    It has to be the ground then of the brake magnets. If they are all getting voltage and not applying the problem is the grounds. Make sure the magnets are connected to a clean portion of the trailer frame or you can run ground wires from each magnet back to the main ground of the trailer wiring harness. When the magnets are activating you should hear them click as they grab the drum and you'll also hear a low hum too.

  • Trailer Brakes on 1 Axle are Weak on Tandem Axle Trailer
    Having the tires off the ground only means that the brakes just have to stop the tires from spinning and not the momentum or weight of the trailer so it is not surprising that the trouble axle seems to work fine in that scenario. Usually when brakes are weak it is because they need to be adjusted. They need to be adjusted so that you hear a slight but constant drag of the pads on the inside of the drum. To see how to manually adjust trailer brake assemblies check out the video I attached,...

  • Testing a Tekonsha Prodigy Brake Controller and Trailer Brake Magnets to Eliminate SH Code
    The SH error code on the Prodigy indicates a general problem with the brake output circuit. In your case, in addition to the magnets possibly causing the problem, it is a good idea to check the rest of the system as well. I would 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 beginning to show through the friction surface of the magnet then they will need to be replaced. To further test your magnets,...

  • Brake Magnets Needed for 2010 Surtrac Trailer with 5200 LB Axles
    I spoke with my contact at Dexter Axle and if there is any question regarding capacity, he recommends going with a magnet for a 7K axle brake assembly. The magnet is interchangeable so if you do indeed have brake assemblies for a 6K axle, it will still work for you. The magnet will be just a bit stronger but will not cause you any issues. Currently we offer 2 options when it comes to brake magnets for 12 inch x 2 inch brake assemblies. Trailer Brake Magnet, # BP01-180, fits: Dexter...

  • Trailer Brakes on 1977 Camper Will Not Release when Going Forward
    It could be the magnets, wiring, or the trailer connectors on the trailer and truck. First, make sure that the truck and trailer connectors are clean and free of corrosion on the pins and where the wires attach. If you are using a 6-Way round trailer connector, one problem might be the positions of the brake output and 12 volt power pins are switched either on the truck or trailer connector. I would need to know what connectors are being used on the truck and trailer. Check the brake...

  • Do Dexter Nev-R-Lube Hub and Drums Use the Same Brake Components as Other Dexter Hub and Drums
    The Dexter Nev-R-Lube Hub and Drums will use the same braking components as other Dexter Hub and Drums. You would just need to determine the size of the drum in order to determine which parts to use. The magnet you were looking at, part # BP01-180, is for 12 inch drums. The magnet you would use for 10 inch drums is part # BP01-110. Same principle applies for shoes and entire brake assemblies.

  • Electric Brake Assembly Recommendation
    Hubs that will fit those bearings include Dexter Trailer Hub and Drum Assembly for 3,500-lb E-Z Lube Axles 5 on 4-1/2 # 84546UC3-EZ or Trailer Hub and Drum Assembly 6 on 5-1/2 # AKHD-655-35-EZ-K depending on the bolt pattern you have. The brake assemblies part numbers # AKEBRK-35L-SA and # AKEBRK-35R-SA will then work well with the either hub referenced. These will fit 10" diameter, wheel sizes 13", 14", and 15", and are intended for 3,500 lbs axles. Included are video resources...
