R&P Service Insight
Brake assemblies are side-specific and size-specific. Before ordering, match the brake diameter, shoe width, backing plate mount, and left/right orientation to the brake currently on the trailer.
- Side Check: This listing is for the left-hand / driver-side brake position.
- Size Check: Confirm your brake is 12-1/4" x 2-1/2", not the wider 12-1/4" x 3-3/8" style.
- Axle Check: Confirm the axle model and mounting flange style before installation.
R&P Knowledge Hub
Compatibility: Fits compatible Dexter 7,200-8,000 lb axle applications where the 12-1/4" x 2-1/2" brake size and 4-bolt mounting style match.
Vehicle / System Fit: Trailer electric drum brake systems using Dexter D80N, D75, D72, #13N, or #12V axle applications as listed for this part number.
Installation Notes: Do not rely on capacity alone. Always verify drum size, shoe width, mounting pattern, left/right orientation, and wiring condition before replacing the brake assembly.
Performance Insight: Forward self-adjusting brakes are designed to help maintain proper shoe adjustment during normal forward braking, which can reduce manual adjustment needs when the system is installed and functioning correctly.
Brand & Fitment Note
Selling Brand: Dexter
Application Reference: Dexter axle model references are provided for fitment guidance. Final fitment should be verified by the brake size, mounting style, axle model, and the existing brake assembly.
What This Means: This listing is for one Dexter left-hand electric forward self-adjusting brake assembly, part number K23-622-00.
Before Ordering: Verify measurements, mounting style, left/right orientation, axle application, drum compatibility, and included components before installation.
R&P Repair Insight
Electric brake replacement is usually straightforward when the correct assembly is matched, but mismatched brake width, side orientation, or mounting style can stop the repair immediately. Compare the old assembly before opening or installing the new one.
- Do Not Mix Styles: Forward self-adjusting and manual adjust brake assemblies should not be mixed by axle or by trailer.
- Inspect the Drum: A new brake assembly should be paired with a drum that is within usable condition and matched to the correct brake size.
- Check Wiring: Inspect magnet wiring, trailer wiring, grounds, and brake controller output while servicing the brake system.
