Video Transcript for Review of Dexter Axle Trailer Brakes - Replacement Magnet - BP01-225

Jeff Hello everybody, this is Jeff Today I'm gonna take a look at this replacement trailer, brake magnet for the Dexter axle, 4,400 pound and 7,000 pound electric brake assemblies. Now this magnet will allow you to replace the worn out magnet on your Dexter trailer brakes. And what's nice is, just by changing the magnet only, it'll save you money and time because it's better than replacing the whole entire brake assembly. You can see this magnet is a nice oval design. So it does include the, or it does increase the efficiency of the magnet, helps extend the life of the magnet.

If you notice the wires that come out of the magnet, they have this nice sharp, protective sleeve here on it. And the reason they do that is 'cause when this is installed on your brake assembly, this portion of the wire goes through the backing plate, and you want to make sure that the wire is protected so it doesn't rub against the opening in that backing plate and cause those wires to, cause a short somewhere. Now the wires, you can see there's two of them, they are black wires. One will connect to a ground, the other connects to your brake feed. And because they're both black, either wire can be used for either function.

This does replace the brake magnet on your Dexter axle electric brake assembly. It works with the 10 inch by two and a quarter inch 4,400 pound brake assemblies and the 12 inch by two inch 7,000 pound brake assemblies. As you can see, this part will include everything I laid out here on the table. The magnet itself, the spring, and then the retainer clip that'll hold the magnet to the brake lever on your brake assembly. But that should do it for the review on the replacement trailer, brake magnet for the Dexter axle, 4,400 pound and 7,000 pound electric brake assemblies..

  • Info Needed to Pick Out Replacement Bearings for Trailer
    Get the hub off and get me either the diameter of the spindles where the bearings ride or the numbers stamped on the bearings. If there is a set of Dexter brake assemblies used currently there's a very good chance you have a standard hub that we'd have bearings for.

  • Availability of Replacement Brake Magnet for 7k Trailer Axle Assembly
    If the assembly is humming when you apply the brakes that's a good sign. That means it's working and is totally normal to hear. I'd need to know more info on your assemblies though to pick out magnets. I'd need to know the brand if you can find it. Most likely it's a Dexter assembly and you'd need the part # BP01-225.

  • How to Pick Out Replacement Trailer Brake Magnets
    We carry several replacement trailer brake magnets that are all designed to fit specific models of brake assemblies. If yours don't seem to be close enough to the armature surface of the hub then it would seem that you do not have the correct magnets or your hub isn't seated all the way on the spindle. I attached a link to a page that has all of the brake magnets we carry. You would want to select the brand and brake assembly size from the filters on the page and the correct ones will...

  • Trailer Brakes Release Intermittently on Enclosed Car Trailer
    The fact that the braking issue happens when you are towing the trailer but not when it is sitting still for testing makes me think that there is a loose connection somewhere that is affected by movement of the trailer and vehicle. The first places to look are the vehicle and trailer side connectors. Make sure each of them is clean and free of corrosion inside where the wires attach and outside on the pins. Make sure the wiring going to the trailer brakes is not pinched or sandwiched between...

  • Troubleshooting Amperage On Brake Magnets
    When you are testing the brakes you will need to sever both of the magnet wires. You can connect one of the wires to a 12-volt battery with a multimeter between the positive battery post and the magnet. Then connect the other magnet wire to the negative post of the battery. If you have 10 or 12 inch brake magnets the reading should be 3.2 to 4.0 amps at 12-13 volts. For 7 inch brake magnets the reading should be between 3.0 and 3.2 amps at 12-13 volts. If your amperage is greater than...

  • Troubleshooting 1 Of 4 Brake Assemblies Locking Up On Tandem Axle Travel Trailer Camper
    A brake controller will not cause one brake to lock up while the other 3 work fine. The common causes for this is the brake assembly not being adjusted correctly or a damaged part inside the brake assembly. Since you mentioned that the brakes are adjusted properly the issue may be a bad Brake Magnet # BP01-225. I have linked an article below that will help you test your magnet to determine if that is the issue. Do note that different brakes have different magnets. You can also pull off...

  • Which Magnets are Recommended for 12 inch Dexter Trailer Brake Assemblies
    Depends on the capacity Dexter axle you have. If your 12 inch drum axles are 6k rated the magnet you would need as a replacement is the part # BP01-180. If instead you have a 7k axle the correct magnet is the part # BP01-225.

  • What Trailer Brakes Will Accept Replacement Magnet # BP01-225
    The replacement magnet, # BP01-225, fits several different brake assemblies. it fits Dexter 10 x 2-1/4 inch assemblies, Dexter 12 x 2 manual assemblies and 12 x 2 Nev-R-Adjust assemblies, 7K axles. For a brake magnet with a red wire we have # BP01-285. It fits Hayes and AL-KO 12-1/4 x 3-1/2 inch assemblies (see product page for specific years). However, these magnets are for 9K to 12K axles. As long as you have the correct magnet, the wire color will not matter. One of the wires will...

  • Is # BP01-225 a Replacement for # BP01-180 Brake Magnet
    According to my contacts at Redneck Trailer Supply, the less expensive BP01-225 is indeed an acceptable replacement for the BP01-180 brake magnets on your 12x2 Dexter brake assembly.

  • Comparing Trailer Brake Magnets # BP01-225 and # BP01-180
    The Trailer Brake Magnet, # BP01-225, that you have referenced is designed for use with 12 x 2 inch Dexter electric drum brakes for 7,000 pound capacity axles. A similar magnet, # BP01-180, fits Dexter 6K, Alko 6K and 7K after 1988 (excluding centerline), and Hayes 6K and 7K after 1988 (excluding centerline) 12 x 2 inch drum brakes. Both magnets have 1 wire for ground, and 1 for power and it does not matter which wire is used for either function.

  • 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 12"...

  • Will the Dexter # BP01-225 work as a Replacement part for the # BP01-180 or BP01-185
    According to my contact at Dexter, the Dexter # BP01-225 is rated for use on up to a 7K axle and it is intended to fit Dexter and Dexter Nev-R-Adjust brake assemblies. It has a larger profile and may not fit on Hayes/Alko brake assemblies. Where as the # BP01-180, is also rated for use on up to 7K axles, and it is considered a fit for Dexter and Hayes/Alko brake assemblies. The # BP01-185 is rated for use on up to 6K axles, and is considered a fit for Dexter brake assemblies. If you...

The hole in the magnet goes over the upright part of the arm and rests on the spring. Then, all you have to do is replace the clip that holds the magnet to the arm. If you need the retaining clip we sell them in a pack of 10 with part # AKBRKR-MC.

  • Which Trailer Brake Magnets Do I Need to Use
    The difference between these two parts comes down to the size of the brake assembly and hubs that are on your axles. The # AKBRKR-M10 that has green wires are designed for 10" electric brake assemblies, where the # BP01-225 are designed for 12" brake assemblies. You would want to choose which one is best for your trailer brakes based off of the size of the brakes/hubs. Typically if you've got a 3500-lbs axles, you'll need the # AKBRKR-M10. If your trailer has 5200-lbs axles or larger...

  • Troubleshooting One Electric Brake Assembly Not Functioning On a Tandem Axle Trailer
    You can run a jumper wire to the trailer brake that is not working to determine if the wiring may be damaged that goes to that brake assembly. Often times axles will have a wire that runs through the axle to the other side for that brake assembly. There is a chance that the wire became damaged inside the axle. You can test the wiring to the brake assembly with a Multimeter # PT89ZR to determine if you are getting the same voltage and amperage to the brake assembly. If you are getting...

    We do carry replacement magnets and other parts for electric drum brakes, including some older designs. I linked the replacement magnets we carry for 12 x 2 brakes, parts # BP01-225 and # BP01-180. However, mobile home axles are not intended for continuous use on a trailer. Mobile home axles are manufactured to be strong enough only for one use to transport the dwelling to its destination - just that one time. Mobile home axles are not safe for ongoing use on a trailer.
