SEHNSUCHT Trailer Electric Brake Kit — Pair 10" x 2-1/4" Manual-Adjust Brakes, 5-on-5" Bolt Circle for 3,500 lb Axles

This SEHNSUCHT kit supplies a matched pair of 10" x 2-1/4" manual-adjust electric brakes with 5-on-5" bolt-circle brake drums, bearings, seals and hardware to convert or replace brakes on 3,500 lb trailer axles (fits 1-1/16" to 1-3/8" spindles; not for 5 on 4.5" bolt patterns).

Whether you're restoring a trailer, upgrading worn parts, or replacing a seized hub, this all-in-one assembly bundles drums, hubs, bearings, seals, dust caps and both left/right electric brake assemblies so you get a ready-to-install pair. The drums are cast iron with electroplated protection to resist corrosion, while the brakes are the classic 10" manual-adjust style built for dependable stopping on single 3,500 lb axles. Check fitment carefully—this kit does not fit Nev-R-Lube axles or certain Airstream Classic models made after July 2005, and it’s designed for the 5 on 5" bolt circle only.

How does this kit improve trailer braking performance?

The matched drums and electric brake assemblies are engineered to react crisply under load and give predictable stopping on trailers rated around 3,500 lb. Manual adjust shoes maintain contact and response without requiring hydraulic systems.

• 10" x 2-1/4" brake shoes for consistent friction area
• Manual adjust mechanism for straightforward shoe take-up
• Electroplated iron drums resist rust to keep braking smooth
• Comes with left and right brake units for balanced braking

What components are included and why they matter?

This kit arrives with complete hub/drum assemblies plus the internal hardware needed to finish installation without sourcing parts separately. Bearings, seals, nuts and dust caps are matched for correct tolerances and to preserve bearing life when properly installed.

• 2 brake drums with 5-on-5" bolt pattern and hub faces
• Bearing inner rings for L68149 and L44649 dimensions included
• 2 grease seals, 2 dust caps, 2 rubber dust plugs and 10 hub nuts
• Left and right 10" electric brakes with springs, washers and cotter pins

Will these drums and brakes fit my axle and spindle?

Fitment is specific: designed for 3,500 lb axles using a 5 on 5" bolt circle and spindles 1-1/16" to 1-3/8" in diameter. They do not fit 5 on 4.5" bolt patterns, Nev-R-Lube axles, or some Airstream Classic trailers built after July 2005—measure your flange before ordering.

• Intended for standard-lube 3,500 lb trailer axles
• Fits spindles with 1.062" to 1.377" inner bearing ID compatibility
• Not compatible with certain sealed-lube or specialty axles
• Dust caps require gentle hammer seating during install

Who is this for? This SEHNSUCHT kit is aimed at trailer owners, DIY mechanics and small fleet operators who need a full replacement brake and hub set for 3,500 lb axles. It’s practical for restoring older trailers, converting to electric brakes, or replacing worn drums and bearings with matched parts to ensure safe, balanced braking. Make sure your hub bolt pattern and spindle specifications match the kit before purchase to avoid fitment issues.
