JADODE 12 x 2 Electric Trailer Brake Assembly — 2-Piece Set for 7000 lb Axles, #42 Spline, 6/8-Lug Fit

JADODE 12" x 2" electric trailer brake assembly is a two-piece replacement set engineered to restore braking performance on 5200–7000 lb axles that use 12x2 drums.

These brakes are a direct-fit replacement for many common 12" x 2" trailer brake applications and match popular OEM patterns so you can quickly swap worn units. Designed to fit center drum holes of 3-1/4" and compatible with #42 splines, this set works with both 6- and 8-lug wheels and is marketed for trailers rated up to 7000 pounds. The brakes are electric-actuated and require manual adjustment during installation and periodic maintenance thereafter.

Will these brakes fit my 7000 lb trailer axle?

They are compatible with many 7000 lb axles when your drum and hub match the specified dimensions and bolt pattern. Confirm drum spline and bolt spacing before ordering to ensure correct fitment.

• Designed for 12" x 2" brake drums with a 3-1/4" center hole
• Fits #42 spline drums (spline size compatibility)
• Works with 6-lug or 8-lug wheel bolt patterns
• Bolt hole spacing: 2.0" O.C. top and 3.0" O.C. across bottom

How do I install and adjust these electric trailer brakes?

Installation generally follows standard trailer brake procedures: remove the drum, unbolt the old assembly, position the new unit, and reconnect the wiring. These units are not self-adjusting, so you must set shoe-to-drum clearance during installation and check adjustment periodically for reliable stopping power.

• Requires manual adjustment on installation and during maintenance
• Reconnect electric actuator wiring per your controller instructions
• Verify shoe clearance and drum runout after mounting
• If unsure, have a qualified trailer technician complete the setup

Which part numbers and brands do these replace?

The JADODE assemblies are made to be compatible with a range of established replacement numbers and aftermarket units, simplifying upgrades or repairs. Cross-references help you confirm interchangeability with popular axle and hub components.

• Cross-replaces K23-180-00 and K23-181-00
• Compatible with 77-12EA-1-2 and Axletech B12E-22 (12x2)
• Suitable substitute for many Al-Ko and Lippert 12x2 units
• Sold as a set of two brake assemblies for both sides

Who is this for: This JADODE brake assembly set is aimed at trailer owners, RV and camper owners, and fleet operators who need a reliable, direct-fit replacement for worn 12" x 2" electric trailer brakes on axles rated up to 7000 lb. Choose these if your trailer uses #42 splines, your drums have a 3-1/4" center opening, and you have the ability to perform or arrange manual brake adjustment. If you prefer self-adjusting systems, consult a technician or consider alternative kits that include that feature.
