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

JADODE 12" x 2" electric trailer brake assemblies are a pair of replacement drum brakes designed to fit 7000 lb trailer axles with 6- or 8-lug wheels and #42 spline drums.

This set includes two 12" x 2" brake assemblies engineered to replace common OEM and aftermarket parts (23-108-00 / 23-181-00 and equivalents). Each unit is built for medium-duty trailers rated up to 7000 pounds and is compatible with both electric and hydraulic actuated systems, making it a versatile option for many boat, utility, or cargo trailers. Installation requires manual adjustment after mounting; they are not self-adjusting.

Will these brakes fit my 7000 lb trailer axle?

These assemblies are intended for trailers with 7000 lb axles that use #42 spline drums and either 6- or 8-lug wheel patterns. Verify bolt hole spacing and center bore to ensure proper fit before purchase.

• Brake size: 12" diameter x 2" width shoes
• Center hole (hub bore) diameter: 3-1/4"
• Compatible with 6-lug or 8-lug wheel bolt patterns
• Designed for #42 spline steel brake drums

How do I know these will replace my current part numbers?

JADODE brakes are cross-referenced to common replacement numbers and aftermarket models used by several manufacturers. Compare your current brake part number and drum specs to confirm compatibility.

• Cross-replaces: K23-180-00, K23-181-00
• Also compatible with 77-12EA-1-2 and Axletech B12E-22 (12x2)
• Fits many Al-Ko and Lippert style hubs with same spline and bolt patterns
• Check measurements (spline, bore, bolt spacing) before ordering

What installation and maintenance should I expect?

These brake assemblies are not self-adjusting, so they require initial manual adjustment at installation and periodic checks afterward. If you are unfamiliar with trailer brake adjustments, professional installation is recommended to ensure safe operation.

• Manual adjustment needed after installation and periodically
• Follow torque specs for mounting hardware and wheel studs
• Inspect shoes, hardware, and electrical connections regularly
• Use a qualified technician if unsure about brake setup or adjustment

Can these work with electric and hydraulic systems?

Yes — the JADODE assemblies are built to function with electric actuation and are suitable for hydraulic setups that use compatible electric-style backing plates. Ensure your actuator type matches the brake magnet and wiring configuration.

• Designed primarily for electric actuation; compatible with certain hydraulic conversions
• Check magnet orientation and wiring for proper connection
• Confirm actuator force and trailer controller settings for optimal performance
• Replacement hardware included where applicable—verify contents prior to install

Who is this for? If you own a medium-duty trailer rated around 7000 lb and need reliable, serviceable replacement drum brakes that match #42 spline drums and common 6/8-lug hubs, these JADODE 12" x 2" assemblies are a practical, cost-effective option. They suit DIY mechanics comfortable with brake adjustment and professional shops replacing worn or damaged backing plates. Avoid these if you require a self-adjusting system or have incompatible spline, bore, or bolt patterns.
