Features to know about

Steadier Braking on Every Trip: Integrated ABS Tow Assist

When traffic slows fast or road conditions shift, these Dexter electric brake assemblies keep things smooth and predictable. Each 12-1/4" x 2-1/2" assembly has an integrated ABS sensor that communicates with Dexter’s Tow Assist system to reduce wheel lock-up and apply selective braking that helps cut down on trailer sway. The result is steadier stops and more control when it matters most.

Consistent Stopping Power Without Adjustments: Nev-R-Adjust Design

No more crawling under the frame to tweak your brakes. The self-adjusting Nev-R-Adjust setup automatically maintains proper shoe clearance as the brakes wear, keeping stopping power consistent over time. You just bolt them on, wire them in, and the system handles the rest—mile after mile.

Simple Electric Setup That Works With Your Controller

These are fully electric brakes designed to work with your in-cab brake controller—no hydraulic lines or actuators required. Once installed and powered, the Tow Assist system reinitializes automatically and runs a self-check before each trip, showing a steady green light when everything’s good to go.

Matched for Dexter 7,500-lb ABS Axles

Each pair of left- and right-hand assemblies is built specifically for Dexter ABS 7.5K axles with a 4-bolt mounting flange. They fit 15" and larger wheels and include bonded brake shoes and proven magnet hardware for durability you can count on over long hauls. A 5-year limited warranty backs up the design for added peace of mind.

See what our Experts say about this Dexter Trailer Brakes

  • Can I Use Time-Delayed Brake Controller With Dexter ABS Brake System, Or Just Proportional?
    Jeff, technically a timed controller will work, but Dexter strongly recommends an inertia-based proportional brake controller for the Tow Assist system. Timed controllers can trigger the ABS more often than needed because they apply power on a preset ramp instead of responding to your vehicle’s actual deceleration. Proportional units like the Tekonsha Prodigy P3 or Redarc Tow-Pro Elite are both verified compatible. What controller are you using now? I can let you know whether it’s on Dexter’s...

  • Do I Have To Adjust New Dexter ABS Brakes After Installing On Trailer?
    Nope - that’s one of the perks of these. All models of Dexter ABS Brake Assemblies, such as 3.5k # DX73WR, 4.4k # DX83WR, 7.5k # DX23WR, and 8k # DX55WR, are Nev-R-Adjust brakes. They’ll automatically maintain the proper shoe clearance once they’re burnished in. Just make sure to follow Dexter’s break-in procedure - about 20–30 controlled stops from 40 mph - so the shoes seat evenly. Brian, are you replacing a single axle or doing all four corners? It’s best to do them all at the same...

  • Can Dexter 8K ABS Tow Assist Brakes Be Used As Upgrade On Dexter ABS 7k Or 7.5K Axle?
    Ron, they can’t - even though both the 7.5K # DX23WR and 8K # DX55WR ABS Tow Assist brakes are 12-1/4" diameter, they use different shoe widths and hardware that match specific drum depths and axle components. The 7.5K brakes use a 2-1/2" wide shoe, while the 8K version steps up to a 3-3/8" shoe. That extra depth means the 8K backing plate, drum, and magnet sit farther out, so they won’t line up correctly on a 7K or 7.5K hub. If your axle tag lists 7,000 lbs, the correct ABS replacements...

  • How Can I Tell If I Need 7K or 7.5K or 8K ABS Brakes For Horse Trailer Axle With Anti Lock Brakes?
    Heather, most horse trailers in that weight range run 7K, 7.5K or 8K axles, depending on the model year. The easiest way to tell which you have is by checking the axle tube or bearing combination: A 3" tube with a 14125A outer bearing usually indicates a 7K axle. If this size the correct ABS brakes are Left # DX69WR and Right # DX79WR. A 3" tube with a different drum depth (12-1/4") means you’ve got the 7.5K axle, with the correct ABS brake assemblies being # DX23WR. A 3-1/2" tube using...

  • Do Dexter ABS Tow Assist Brakes Need Setup After Installing New Brake Assemblies? How To Sync?
    Travis, the ABS system’s smart enough to handle that on its own. Once you install the new assemblies - like the # DX23WR for 7.5K or the # DX55WR for 8K axles - you just reconnect the brake wiring and ABS plugs when installing the hub, torque the hardware, and power the trailer up. The Tow Assist controller does a self-check every trip and will show a steady green light when it recognizes everything’s working. Did your indicator light come on amber after you swapped parts and you're still...

  • Can I Just Replace One Side Dexter Brakes On 7.5k Anti Lock Brake Axle With Tow Assist?
    Greg, it’ll technically function, but Dexter (and etrailer) recommends replacing in left/right pairs per axle. Mixing new and worn shoes changes the braking and feedback the ABS system expects, which can cause it to pulse unevenly. Even on non-ABS systems, it's still best to replace pairs per axle for even braking. For consistent braking, swap both the left and right # DX23WR assemblies at the same time, then let the system reinitialize when you reconnect power. Was your replacement due...
