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.

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

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

  • 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 par

  • What Size Nuts and Studs are Used to Mount 7 and 10 Inch Trailer Brake Assemblies
  • The studs on the Dexter 7 inc brake assembly, part # 23-47, are 1-1/4 inch long with 7/16 - 20 threads. Brake Assembly mounting bolt, part # 7-75, is 1-1/4 inch long with 7/16 - 20 threads. The nuts, part # 6-17, are also 7/16 - 20. This size is pretty standardized as far as 7 inch and 10 inch brake assemblies.

  • 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. I would recommend the Pollak trailer connector, item # PK12706, for ease of i

  • 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. I

  • Parts Needed to Install Electric Brakes On 1995 Coleman Destiny Royale Trailer
  • To make sure that you get the correct parts, I would need to know the inner and outer bearing numbers stamped into the metal of the bearings. There are different 5 lug bolt patterns. Use the FAQ I have linked to measure for bolt pattern so you can get the correct hub and drum assemblies. If you do not have EZ Lube axles, you will not need EZ lube hub and drum assemblies. If you do have L44649 inner and outer bearings and the seal has a 1.987 outer diameter and 1.5 inch inner diameter, you

  • Will My Original Hubs Work When Changing Hydraulic Brakes to Electric Brakes
  • Typically hubs and drums for hydraulic brakes are not machined properly to work with electric brakes. A few things that you will want to look at are the armature surface of the drum and make sure it has a smooth consistent surface for the magnet from the electric brakes to contact. You will also want to make sure that the drum will fit on the brake assembly. I have attached two photos for you to check out. One photo shows what the armature surface is and the other photo shows the difference

  • 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 may

  • 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 pads o

  • Pros And Cons For Switching From Electric To Electric Over hydraulic Disc Brakes On Trailer
  • In order to switch from your electric brakes to a disc brake system there are several things you will want to consider. It is true that the disc brakes will provide better braking for you, although converting can require an involved installation. Electric trailer braking systems provide fast response times and good control over the action of your trailer brakes, but they don't stop as hard as hydraulic brakes. Some of the things you need to consider if you decide to change the brake syste

  • Electric Brake Assemblies and Hub and Drum for Snowmobile Trailer with 7x1-1/4 Inch Brakes
  • For Dexter 7 x 1-1/4 inch electric trailer brakes you will use # 23-47 for the drivers side and # 23-48 for a passenger side assembly. For a hub and drum assembly, you may need # 8-173-16UC3-EZ. This has a 4 on 4 bolt pattern and is designed for use with the brakes listed above. It takes inner and outer bearing L44649 and a 10-60 grease seal (included).

  • How to Add Electric Disc Brakes to a Snowmobile Trailer
  • You can convert your setup to an electric disc setup, to do this you will need first to determine what spindle is on your trailer axles and what wheel bolt pattern you have on trailer wheels. To determine what spindle you have you will have to remove your hubs and get the inner and outer bearing numbers. With those numbers you will be able to determine what spindles you have. To determine the bolt pattern of your wheels check out the FAQ article I attached that details how this is done.
