Electric Trailer Brake Kit 3500 lbs

This electric trailer brake kit fits axles rated for 3500 lbs and uses 10 x 2-1/4 in brake assemblies. The set includes two brake shoes and two brake drums made from gray cast iron, SPHC and Q235 steel. A 12 V DC electromagnet draws 2.5 to 3.6 A and produces 450 N of magnetic force. The kit ships with dust caps, nuts, washers, pins and a user manual.

For Single-Axle Trailers Up to 3500 lbs

The kit suits single-axle utility, boat or cargo trailers with a 4-bolt flange on a 101.8 mm PCD and 5-bolt drums on a 143 mm PCD. Builders needing tandem-axle coverage, heavier axle ratings or hydraulic actuation should look at other solutions. Trailers with different bolt patterns or drum diameters will not match the supplied hardware.

Capacity and Service Limits

Each assembly handles the stated 3500 lbs axle rating and the friction material carries a 0.48 coefficient. The manufacturer rates the electromagnet service life at 30000 km under normal use. Beyond that distance or when axles exceed the rated load, braking performance drops and components require replacement.

Questions about this item

Does this kit include the brake controller and wiring harness I need to operate the electromagnet?

The kit provides two brake shoes, two drums, dust caps and mounting hardware; a 12 V brake controller and wiring are not included and must be supplied separately.

Will the 4-bolt flange with 101.8 mm PCD fit my existing 3500 lb axle?

The flange uses four bolts on a 4 in / 101.8 mm PCD with 7/16-20 UNF threads, matching the standard 3500 lb axle pattern.

How can I confirm the electromagnet is drawing the correct current after installation?

With the controller active, measure current at the magnet leads; it should read between 2.5 and 3.6 A at 12 V DC.
