SEHNSUCHT Trailer Electric Brake Kit, Pair 10" x 2.25" Self‑Adjusting for 3,500 lb Axles, 5‑Hole

SEHNSUCHT's Trailer Axle Electric Brake Kit is a complete pair of 10" x 2.25" self‑adjusting electric brakes with matching 5‑hole, 4.5" bolt circle brake drums and hardware designed for 3,500 lb trailer axles.

This kit bundles everything needed to replace or upgrade drum brakes on standard 3,500‑pound trailer axles: two electroplated iron drums, a left and right self‑adjusting electric brake assembly, bearings, seals, dust caps and all mounting hardware. Components are manufactured to resist corrosion and provide dependable braking response in road and marine environments when fitted to compatible spindles and hubs.

Will these brakes fit my trailer axle and spindle?

They are engineered for 3,500 lb axles and fit 1‑1/16" to 1‑3/8" spindles on standard Lube axles. They are not compatible with Nev‑R‑Lube axles, Airstream Classic trailers built after July 2005, or Dexter 4,400 lb backplates.

• Fits 5 on 4.5" bolt circle hub/drum pattern.
• Designed for 10" x 2.25" brake dimensions and 3,500 lb axles.
• Compatible with 1‑1/16" to 1‑3/8" spindle diameters (standard Lube only).
• Not for use with 4,400 lb Dexter systems or Nev‑R‑Lube axles.

What components are included and what tools do I need?

The package contains two drums, two brake assemblies (left and right), inner bearing races, grease seals, dust covers, hub nuts and assorted fasteners so you can complete a two‑wheel replacement. Basic mechanic tools and a hammer for dust cap installation are required.

• Included: 2 brake drums, 1 left and 1 right electric brake, bearings, seals, dust caps, hub nuts, washers and cotter pins.
• Installation tools: socket set, torque wrench, bearing packer or grease, and a hammer for dust caps.
• Measure existing flange and spindle to confirm fit before installing.
• Follow torque specs and check brake adjustment after installation.

How do these brakes perform and resist corrosion?

Drums are cast from high‑grade iron and treated with electroplating to reduce surface corrosion and wear. The self‑adjusting brake assemblies help maintain proper shoe clearance for consistent stopping; however, performance depends on correct installation and regular maintenance.

• Electroplated drum finish limits rust and extends service life.
• Self‑adjusting mechanism reduces the need for frequent manual adjustments.
• Designed for emergency and routine braking on compatible trailers.
• Routine inspection of bearings, seals and shoes ensures reliable operation.

Are there any important installation cautions or exclusions?

Yes. This kit is intended for standard Lube axles and incompatible with certain axle and trailer models. Check spindle type and flange dimensions before you buy; improper fitment can prevent correct installation or damage components.

• Not compatible with Nev‑R‑Lube axles or Airstream Classic post‑July 2005 trailers.
• Not compatible with Dexter 4,400 lb brake backplanes.
• Dust caps must be seated by light hammering—do not force with excessive impact.
• Measure brake flange diameter prior to purchase to confirm fit.

Who is this for: This complete SEHNSUCHT kit suits trailer owners, DIY mechanics and fleet maintainers replacing worn drums or upgrading electric drum brakes on 3,500 lb axles. Choose this set if you need corrosion‑resistant drums, full replacement hardware in one box, and self‑adjusting electric brakes designed for common 5‑on‑4.5" hubs. If your trailer uses a Nev‑R‑Lube axle, a 4,400 lb Dexter backplane, or an unusual spindle, verify compatibility or consult a technician before purchasing.
