• Replacement Dexter Hub Drums and Brake Assemblies for Drums With 8-247 Casting Number
  You have a typical 3500 lb brake hub/drum. The correct replacement drum would be # 84546UC3 for standard spindles or # 84546UC3-EZ for an E-Z Lube spindle. The hubs include the inner and outer wheel bearing, inner and outer races, the grease seal, dust cap and lug nuts. The hub/drums are sold individually. As you can see in the photo, this hub has the same casting number as yours, so it is a proper replacement. The Dexter 023-469 is a self adjusting 10 inch brake assembly. To replace...

• Replacement 7 inch Brake Assembly for Fiat Elnagh 320 Motorhome
  Buongiorno! We do carry Replacement Magnet Kit for 7" Electric Trailer Brake Assemblies - 2,000 lbs Item # AKBRKR-M7. However, it looks like the center mounting hole on yours is round, whereas ours uses a square/rectangular hole. It doesn't appear that the hole on the # AKBRKR-M7 is large enough to allow the arm (on the brake assembly) to fit through. If you scroll to about the 5:40 min mark on the Redline Replacement Magnet Kit video Iinked below, you'll see the arm I'm referring...

• 3,500 lb Trailer Axle Brake Assembly Recommendation
  For 3,500 lb axles you most likely have 10 inch brake assemblies. For replacements you would want the part # 23-27 for the right hand side and part # 23-26 for the left hand side. You can measure your current ones to verify this. If they are 10 inches in diameter and 2-1/4 inches wide these are a fit. These are self adjusting assemblies that made by Dexter and would work great. I attached a review video for more info as well.

• Troubleshooting Low Voltage Output on Brake Controller with Brake Pedal and Override Lever
  Is the gain on the controller set all the way up? If it's set to 3.5v as the max that's as far as it will go with the lever or the brake pedal. Try maxing out all of the adjustment setting to see if that changes anything. What brake controller do you have? What vehicle is it? You have done most of the troubleshooting steps that are recommended so this is a tough one. Hopefully it's as simple as just adjusting the brake controller to a more aggressive setting. Since both the lever and...

• What is Correct Gauge of Wire for Wiring Trailer Brakes
  Yes the issue is related to the wire gauge you have. You need to go with 10 gauge wire like part # 10-1-1 (sold by foot) to deliver the amperage and voltage needed for your brakes to activate. 14 or 16 gauge wire is no where near heavy enough for this task.

• Troubleshooting 8 Volts at Electric Trailer Brakes
  Since you are getting 12 volts at the trailer connector and at each magnet individually it sounds like there is possibly a short between some of the brake magnets or, since you have 6 brake assemblies, maybe you are not using a wire that is thick enough. For a triple axle trailer, you should be using 10 gauge wire. I recommend replacing the wiring with # 10-2-1 and rewire the brakes. Often times, axle manufacturers will only use 12 and sometimes 14 gauge wire on their axles.

• How Tight Should the Nuts be When Attaching a Trailer Brake Assembly to a Trailer
  When installing brake assemblies like the Electric Brake Assembly, # 23-27, that you have referenced, there is no specific torque rating when tightening the nuts on the backing plate. Basically you will want them to be as tight as you can get them using the appropriate wrench. You will not need to use a breaker bar for extra torque when tightening the nuts. Take a look at the two videos linked below. Our installer does not mention a specific torque rating, but uses a wrench and tightens...

• Identify Older Hayes Brake Magnet
  It looks like a Hayes Brake magnet part number 73400. We do not carry this part but I did a quick internet search and was able to find a couple places that sell them. From the research I did it looks like this is an older style of brake magnet used in the 1980's.

• Should a Trailer Brake Magnet Make Contact with a Drum Even With No Brakes Applied
  The magnet should only make contact with the inside of the brake drum when power is applied to the magnet. If it is making contact with the drum all the time, you may have residual power running on the brake wire that is just enough to cause the magnet to grab the drum. You will need to check the magnet power wire with a circuit tester, # 40376, to see if there is any power when the brakes are not applied. If there is, there is a short circuit somewhere and you will need to track it...

• How do You Determine If a Trailer Brake Magnet is Worn Out
  If the brake magnet is worn to the point that the windings are visible then you know it's time to replace the magnet. However, magnets can also fail without the visible signs of wear. Check out the FAQ article I attached on testing brake magnets to see how to test your magnets to be sure they are functioning properly. I checked all of the replacement magnets we carry and none of them look like the magnet you submitted a picture of. If you determine you need to replace the magnets you...

• Do Electric Trailer Brakes Work in Forward and in Reverse
  Yes, electric brake assemblies will work in reverse. The brake controller in your tow vehicle would still activate in reverse as long as the brakes are applied. The actuating arm of the Dexter assemblies part # 23-27 will apply the brakes when pushed in either direction. That means that in forward or reverse the assemblies will still apply trailer brakes.

• How to Choose Replacement Drums and Brakes for a 1966 M416 Military Trailer
  Due to the age of the trailer, we will want a little more information to make sure we get you the correct hub and drum assembly and brake assemblies. The best way to choose a replacement hub is by using the bearing and grease seal part numbers that are stamped into the metal cage of the bearing and the rubber of the seal. With these part numbers, I can cross reference the correct hub. If you cannot determine the part numbers of the bearings or seals, then the next best option is to...

• Trailer Brakes are Very Weak Even After Adjusting Them
  Since the trailer was off of the ground it would not take much voltage to stop the wheels from spinning so they may be getting power but they may not be getting enough power due to a short or wiring issue. But 9 times out of 10 weak trailer brakes indicate that the brakes need to be adjusted. Since you adjusted the brakes and that did not help it could be time to replace the shoes. If enough of the pads has worn away they will not be able to adjust out far enough to make good contact...

• Brake Assembly Recommendation for a Lippert 3,500 lb Trailer Axle
  The 10" Electric Trailer Brake Assembly # 23-27 that you referenced should work well on your Lippert 3,500 lb trailer axles. Your Lippert axles should use a 4 bolt mounting flange and have hub/drums that are 10 by 2-1/4 inches like what this assembly is designed to fit. For the matching left hand side assembly you would want the # 23-26.

• What is Needed To Install Electric Brakes On A Master Tow Dolly That Doesnt Have Brakes
  Before installing brakes on your trailer, you will need to know some basic information about your existing trailer. The first thing you will need to find out is if your tow dolly has a brake mounting flange mounted on your existing axle. The brake mounting flange provides a secure attachment point for a brake assembly. If you have a mounting flange, send me a picture or dimensions. See diagram to the right. This will help determine your existing brake mounting flange pattern. If you...

• Troubleshooting a Dragging Electric Brake on a Trailer
  It sounds like there is an electrical short on your trailer wiring that is activating your left rear brake assembly and that is why the brake continues to drag and get hot. Since you have swapped the brake assembly out and still had the problem you know the problem is not in the assembly but somewhere else on the trailer wiring. I would start at the wiring near the brake assembly and check for corrosion and loose or exposed wires and fix as necessary. You will want to trace this back...

• Troubleshooting Low Voltage Output from Brake Controller
  Something is obviously causing a voltage drop between the brake controller and the trailer connector. The usual culprit in this type of situation is a break in the wire or a corroded wire. Check the wiring under the truck. You should be able to trace the trailer connector wires from the back of the trailer connector up toward the front of the truck. Look for any sections that look like they may have been pinched, frayed or even eaten through. If there are any wires spliced in or quick splices,...

• Testing Trailer Brake Magnets with a Multimeter
  You may have a problem with the brake magnet. First, since you have had the brakes apart, if you happened to notice any of the windings coming though on the magnets, that would indicate that they need to be replaced. Beyond that, in order to test the brake magnets, you will need to use a multimeter, like # PT89ZR. We have an FAQ article on how to test the magnets and what to look for as far as resistance, amp draw, and testing for shorts. I have included a link to it for you to view.

• How Do You Know When Trailer Brake Pads/Drums Need to Be Replaced
  You would know to replace brake shoes the same way you would know with a vehicle. If performance is suffering and adjusting the brakes does not help and there are no other issues causing the poor performance it is probably time to change the brake shoes. Some shoes that have pads that are riveted on should be replaced once the pad wears down to that rivet. When you have the hub off the axle inspect the inside of it. Does it look torn up where the magnet rides or where the brake pads...

• Tips to Keep a Proportional Brake Controller Level When Installing
  Electric proportional brake controllers are required to be manually leveled by hand according to the parameters outlined in the installation instructions. Not all brake controllers have the same mounting range so you need to make sure you follow the instructions. One thing proportional brake controllers have in common is that in addition to the specific mounting range, they also cannot be tilted left or right or lean to one side or the other. They need to be mounted in the direction...

• Low Voltage to Trailer Brakes After Installing New Brake Assemblies
  Its not uncommon for there to be slight voltage drop off over a certain distance but with the brake controller set to the maximum you should still be getting 12 volts at the brake magnets. We need to determine if the low voltage is coming from the controller or somewhere down stream. What you will do is sever the brake controller blue wire several inched back from the controller. Then use your meter to test for voltage on the end of the blue wire coming from the controller while applying...

• Do Electric Trailer Brakes Work in Reverse
  When the brake magnet is pushed in either direction on the brake assembly (forward or backward), the brake shoes are forced apart which activates the trailer brakes. When pushed backwards the brakes won't apply quite as hard as when going forward, but they still do work. I have had brake assemblies at my desk and wondered the same thing so I pushed the actuating arm forward and backwards and found that either direction causes the shoes to push out.

• Proper Adjustment of 10 Inch Electric Brakes On Trailer
  To adjust your brakes, you will want use a brake adjustment tool and turn the adjustment gear which is accessible through the back of the brake assembly. You will want to tighten the gear so that you cannot turn the wheel, then you will want to back the gear off 10 clicks. This will be the proper adjustment for the brakes and will need to be repeated on each brake assembly of the trailer (see video link). Another adjustment you will want to make is with your brake controller. If your...

• Troubleshooting New Trailer Brakes Where One Side of Trailer Brakes Harder than the Other
  If the adjustment of both brake assemblies are good and you can notice that the one side of the brakes are pulling harder than the other that would lead me to believe that the problem is the grounds of the brake assemblies on the right side of the trailer. A lot of times trailer brakes ground to the frame. I would just run all of the grounds back to the main ground harness of the trailer to see if that fixes the problem. The other problem is that it could be that your brake magnets are...

• What Do Old Warner Trailer Brake Assemblies Look Like
  Those are Warner trailer brakes. This style is not made anymore and replacement parts are hard to find. We have some parts for the larger Warner assemblies but NOT the 12 x 2 inch ones. Most people end up replacing them. You will have to have standard brake mounting flanges welded to the axle, see link, if it doesn't have them already. You will also need to replace the hub and drum assemblies. For that I would need to know the inner and outer bearing numbers stamped into the sides of...
