Video Transcript for Dexter Trailer Brakes 23-47 Review

Today we're looking at part number 23-47 from Dexter. This is a seven inch by one and a quarter inch electric brake assembly. The capacity for the pair is 2000 pounds and it mounts with four bolts. So, here are the bolts on the back. I think you can see these. The measurement from center to center, one bolt to another is two and seven eighths of an inch.

So you want to make sure that the mounting flange on your axle matches that measurement. You have two wires. One is for ground and one is for power and it does not matter which wire you use for which function. Now, the way you can tell that this is a left hand electric brake assembly is to look at the brake shoes. You have one here that's that long. You have one here that's shorter.

The shorter or smaller brake shoe always faces the front. Also, what must always face the front is the metal C-shaped actuating arm right here. So, if that's facing the front this is a left-hand brake assembly. The way this is measured is from the outside, the exterior edge from the brake pad from one to the other. So, going across the center here, from that outside edge to the other is seven inches. Then the other measurement is determined by the width of the brake shoes, which is one and a quarter inches.

The mounting nuts and the washers for these assemblies are sold separately and are required for installation.There you have it for part number 23-47 from Dexter the seven by one and a quarter inch left-hand electric brake assembly.

Ordered my parts on Tuesday... showed up on Thursday! Awesome delivery time. Read the reviews for the 7" brakes I needed to replace on my popup camper, and several folks said to make sure to order the bolts, nuts and washers - since the etrailer replacements didn't come with them. The 7" brakes DO infact come with the pressed-in bolt studs already in place, the only thing extra you'll need to get would be the nuts and lock washers if you don't already have them. Installation is as simple as bolting them on and crimp connecting two wires. I'll make final adjustments to the brake controller once everything is back in place. 55385

This brake assembly replaced my original electric brake on 2004 Fleetwood/Coleman Sedona. You need to order four nuts for the brake mounting bolts on each assembly. etrailer's service/delivery was extremely fast with the free shipping on orders over $150. I also bought the LH assembly and matching hubs for the dexter ez axle. I would definitely buy from etrailer again. 46845

The 23-47 brakes are an excellent replacement on my 1997 Coleman Fleetwood Bayports popup camper that I am close to finishing a restoration process on. They fit perfectly!

I purchached these brakes to convert from hydraulic surge brakes on my 1973 pop-up camper. It was a simple, bolt on conversion that took only a few hours to complete; including wiring. One week later, they performed flawlessly on the 400 mile trip to hunting camp. Thanks e-trailer for a great product and service. 59443

Ask the Experts about this Dexter Trailer Brakes
Do you have a question about this Trailer Brake?

  • Parts Needed to Install Electric Trailer Brakes on a Pop-Up Camper
  • You have compatible hub and brake assemblies selected. The brake assemblies, # 23-48 right hand, and # 23-47 left hand, will mount to a 4 bolt flange that has bolt holes 2-7/8 inches apart on center. You will need to make sure your existing bearings and seal match the bearings and seal in the hub and drum you selected, # 8-257-5UC3-EZ, and that the wheel bolt pattern, 5 on 4-1/2 inches, matches also. The trailer hub and drum # 8-257-5UC3-EZ is designed for use on an EZ lube axle with grease...

  • Replacing Electric Trailer Brake Shoes and Magnets on a 2 Axle Scotty Camper with 4 Bolt Wheel
  • The best way to determine the correct parts for your brake assemblies is to either measure the diameter of the brake drum and the width of the pads on the shoes and determine the manufacturer or to use the inner and outer bearing part numbers and wheel bolt pattern to determine the hub on your trailer. The 8-147 number that you referenced is a casting number that is not related to the actual part number. The # 23-27 brake assembly is for 10 X 2-1/4 inch brake drums. Since your hubs...

  • Electric Brakes And Hub And Drum Recommendation for 2,000 Lb Trailer Axle
  • Since you said you need electric brakes and hubs and drums, and the mounting flange has 2-7/8 inches between mounting holes, I recommend the Dexter system. The mounting hinge hole measurements will dictate which brake assemblies will work for you. For the left hand brake assembly I recommend part # 23-47 and for the right hand part # 23-48. These brakes are 7 inch by 1-1/4 and for axles rated up to 2,000 lbs. The hub and drum assembly I recommend is part # 8-257-5UC3. These come...

  • Difference Between Idler Hubs and Hub/ Drums
  • The Dexter Trailer Hub Assembly you referenced, part # 34822BX is known as an idler hub. An idler is a hub that is no provisions for trailer brakes. It has no brake drum. Part # 8-276-5 is an example of a hub/ drum that has a brake drum that can be used with a brake assembly like part # 23-47. The 34822BX would be an acceptable replacement for an idler hub with a 4-on-4 bolt pattern that uses # L44643 bearings.

  • Parts Needed for Adding Brakes to a Utility Trailer
  • You will need Hub Drums that have the hub built into the drum. For part # 23-47 you will need 7 inch Hub Drums, like part # 8-173-16UC3 and mounting flanges, part # 4-34, that will need to be welded to your axles. This size brake and hub drum assemblies are for smaller trailers. You will pick your hub drum based on your wheel and axle size, then you will pick the brakes that fit that hub drum. If you write back with your bolt pattern and bearing numbers, I can help you find the correct...

  • Replacing Electric Brake Assemblies & Hub Seals on Haulmark Sport Lite 2-Axle Trailer
  • We generally recommend replacing brake assemblies on both ends of the same axle at the same time. If wired correctly both brakes on a given axle should tend to wear fairly evenly. Just because the initial electrical braking signal reaches one wheel on the axle before the other there should not be very different wear between the two. If the front/left brake was damaged due to a dead short, then all brakes will cease to function as they are all on a common circuit. The other three brakes...

  • Parts Needed to Change Hydraulic Trailer Brakes Over to Electric Brakes on a 1997 Jayco Tent Trailer
  • You will need two of the 7 inch electric brake assemblies, one right hand, # 23-48, and one left hand, # 23-47. You will also need an appropriate length of 10 gauge wire, item # 10-2-1, for running the wires to the trailer connector at the trailer coupler. Next, you will need a trailer connector to match the wiring on your vehicle, or the wiring you will need to install on your vehicle, to activate the electric brakes.

Your existing bearings and grease seals should have reference numbers stamped on them, make sure the numbers on the existing parts match those of the replacements.

  • Can Drums from a Trailer with 7 Inch Hydraulic Brakes be Used When Converting to Electric Brakes
  • You might be able to re-use the drums. Some 7 inch hydraulic drums are sized differently and will not allow electric brake assemblies to be properly positioned in the drum. Some times the hydraulic drums are too deep and will make contact with the brake backing plate before they are seated all the way on the spindle. The best way to proceed is to try re-using the drums first and if they do not fit get drums made for electric brakes or you can buy electric brake drums from the start. We...

  • Replacement Parts for Electric Brakes on a 1992 Coleman Fleetwood Trailer
  • If by solenoid you are referring to the brake magnets, then yes, we do offer replacement brake magnets depending on the size brakes that you have on your 1992 Coleman Fleetwood. I did some research on your trailer and it looks like you should have 7 inch Dexter brakes, so you could use the Trailer Brake Magnet Kit, # BP01-068.

We sell the nuts individually as part # 6-17 and the lock washer as part # 5-8. You'll need four of each per brake assembly.

  • Parts Needed to Convert to Electric Trailer Brakes or Repair Hydraulic Trailer Brakes
  • You can switch to electric brakes, but there are several parts you will need. First, you need to take a look at the hole pattern for the brake mounting flange. This is the piece that is welded to the axle that holds the brake assembly. The 7 inch brakes you are looking at have a standard 4 hole mounting pattern. If the existing flange has a different pattern, you will need to have the old flange removed and a new one welded on by a qualified professional with experience working on trailers....

  • It sounds like your new axle does have a brake mounting flange, which is what that square piece you are describing likely is. I have included a picture that shows what an axle with brake mounting flanges looks like. For a square brake mounting flange and 2000 pound axle you would use 7 x 1-1/4 inch brakes. You can use # 23-47 for the left side and # 23-48 for the right side. You will also need hub and drum assemblies to replace regular idler hubs. For the correct hub and drum assemblies...

  • Can Trailer Hub and Drum # 8-257-5UC3-EZ be Used with 14 Inch Wheels on a 2K Flexride Torsion Axle
  • You can use hub and drum assembly # 8-257-5UC3-EZ with a 14 inch wheel. However since there will be more force with the larger wheel when it is spinning you will not get the optimum braking performance. All the hubs that have the 5 on 4-1/2 bolt pattern and fit 2,000 pound axles will all say 10 to 13 inch wheels but you can use a 14 inch. Just be aware that the braking performance will not be ideal.

The 7 Inch Electric Brake Assembly, part # 23-48, is for 2,000 lb axles. For the left hand brake assembly, you will need part # 23-47.

For brake assemblies you would want the # 23-48 for the right hand side and part # 23-47. Before you order any parts you would want to pull a hub from your trailer to verify that both bearing numbers are L44649.

  • Adding Electric Brakes to 1999 Jayco Pop-Up Camper Trailer
  • Jayco offered its 1999 Pop-Up camper trailer with and without brakes. Typically pop-up campers are equipped with electric drum brakes. It is likely that the brakes are bad or there is a wiring issue on your 25 year old trailer. Hopefully you have a brake controller. If there was a wiring issue or if there were no brakes on the trailer at all, then the brake controller should have indicated so. First you want to determine if you have brakes or not (hub and drum vs. idler hubs). An...

  • Will 10 Inch Trailer Brakes Fit In Place of 7 Inch Brakes
  • Ten inch brakes will use a larger hub than 7 inch brakes. So you will not only have to change the brake assemblies but also the hubs and the wheels. If cost is not a factor then you can do all of this but it would be much easier to just replace the 7 inch brakes. If the brakes are not providing enough power there may be another issue to look at. Make sure the brakes are properly adjusted. To do this you will turn the adjustment wheel until you can hear a slight but constant drag of the...

  • Replacement Brake Assembly Recommendation for a Trailer that Has 7 inch by 1-1/4 inch Assemblies
  • I would recommend you go with the same dimension assemblies you took off of your trailer. For that you would want the # 23-48 for the right hand side and # 23-47 for the left hand side. Although you have enough room for wider assemblies I wouldn't recommend going to a wider one since the surface of the drum has probably worn where the previous pads were and the new pads wouldn't match up to that surface well.

  • Axles, Springs, Hanger Kit, and Brakes for a Home Made Trailer

It comes with idler hubs with a 5 on 4-1/2 inch bolt pattern for 12 to 15 inch wheels. The axle is rated for 2,000 pounds. To add brakes you would have to have a professional weld on brake mounting flanges, # T0872400....
