Care information

To ensure optimal performance and extend the service life of your new trailer components, please follow these care guidelines after purchase:

Before installation, check all parts for shipping damage or missing components. Do not install damaged parts.
Always use correct tools and torque settings. Improper installation can lead to premature wear or failure.
For bearings, suspensions, and brake components, apply high-quality trailer grease before first use if not pre-greased.
Some parts (like brake assemblies) require a short break-in period to achieve full performance. Follow manufacturer instructions for best results.
Recheck fasteners, grease levels, and moving components after 100 miles of towing, then at regular intervals.
After exposure to water, road salt, or mud, clean and dry parts thoroughly. Apply anti-rust treatment if needed.
If storing unused parts, keep them in a dry, sealed container away from moisture and direct sunlight.

Q1 Will this brake fit my trailer?

This brake assembly fits most standard 7,000 lb trailer axles that use 12" × 2" electric brakes with a 5-bolt mounting flange. Please verify your axle rating and brake dimensions before ordering. If you're unsure, send us your axle tag or hub information and we'll help confirm compatibility.

Q2 Does it fit Dexter or Lippert axles?

Yes. It is compatible with many standard Dexter, Lippert, Rockwell American, AL-KO, and other 7,000 lb trailer axles that use a standard 12" × 2" brake assembly. Always verify your axle specifications before purchasing.

Q3 Is this a self-adjusting brake?

Yes. This is a self-adjusting electric brake assembly, which automatically maintains proper brake shoe clearance during normal operation. This reduces maintenance and helps provide consistent braking performance.

PRODUCT OVERVIEW

Replace or service your trailer brakes with the Dexter K23-458-00 / K23-459-00 Nev-R-Adjust® Electric Brake Assemblies. Designed for 6,000 lb trailer axle applications, these complete brake assemblies feature a 12" x 2" brake size and 5-hole brake flange mounting configuration. K23-458-00 is the left-hand assembly, while K23-459-00 is the right-hand assembly.

Dexter's Nev-R-Adjust® forward self-adjusting system automatically maintains brake shoe clearance during normal forward braking as the linings wear. This reduces the routine manual adjustment required with standard electric drum brakes while helping maintain consistent brake adjustment over time.

Each assembly comes fully built with the brake shoes, magnet, springs, adjuster mechanism, and backing plate already assembled. Choose a single left-hand assembly, single right-hand assembly, one LH/RH pair for one axle, or two LH/RH pairs for two axles depending on your trailer configuration. These brakes are intended for compatible 6K trailer axle applications using 12" x 2" hub-and-drum assemblies and a matching 5-hole brake flange.
