Electric Trailer Brake Assembly 12" x 2

This electric trailer brake assembly fits axles rated for 7000 lbs and uses a 5-hole mounting pattern. The kit includes one right-hand and one left-hand unit, each measuring 12 inches by 2 inches. Self-adjusting mechanisms reduce manual maintenance by keeping pad clearance consistent over time. The backing plates are constructed from SPHC and Q235 steel for structural rigidity.

Suitable for 7000 lb axle replacements

Owners replacing worn brakes on compatible 7000 lb axles with a 5-hole flange will find this pair a direct fit. The asbestos-free semi-metallic pads deliver a 0.48 friction coefficient for reliable stopping power. Builders needing a different flange pattern, a higher weight rating, or hydraulic actuation should look at other configurations. Trailers equipped with 6-bolt or 7-bolt hubs cannot use this kit.

Sustained load performance

The self-adjusting feature maintains consistent pad contact during repeated stops, preventing the fade that occurs when manual adjusters drift out of specification. Magnets draw 2.8 to 4.2 amps at 12 volts DC, producing 600 newtons of magnetic force for steady engagement. Rated lifespan reaches 30000 kilometres under normal operating conditions. Heat dissipation relies on the 2.81-inch brake width and the semi-metallic pad compound rather than forced cooling.

Questions about this item

What axle capacity must the trailer already have for these 7000 lbs brakes to match?

The trailer needs a 7000 lbs rated axle so the pair's 7000 lbs rating aligns with the axle capacity.

Will the 5-hole flange pattern fit the existing 5-hole backing-plate studs on my trailer?

Yes, the 5-hole mounting flange matches a 5-stud backing plate, so the pair bolts directly onto the existing stud pattern.

How can I confirm the self-adjusting mechanism is functioning after installation?

After a few brake applications the shoes centre automatically; even pad wear and consistent 0.48 friction coefficient indicate the self-adjusting feature is working.
