Trailer Brake Assembly for 7000 lbs Axles

This electric brake assembly fits trailers rated at 7000 lbs with a 12" x 2" drum size and five-hole mounting pattern. The kit includes two right-hand and two left-hand units for a complete axle set. Self-adjusting mechanisms reduce manual maintenance after installation.

Thermals Noise and Power Draw

Each magnet draws 2.8 to 4.2 amps at DC12V, producing 600 N of magnetic force during normal stops. Asbestos-free semi-metallic pads with a 0.48 friction coefficient operate quietly without excessive heat buildup. The SPHC and Q235 backing plates dissipate energy steadily across routine towing.

Sustained Load Behavior

The self-adjusting feature maintains consistent pad clearance over the 30,000 km rated lifespan without manual intervention. Brake pads measuring 1.97" x 0.19" resist fade during long descents or repeated heavy stops. Four-unit weight of 59.26 lbs reflects robust construction for continuous axle duty.

Questions about this item

How do I install the 5-hole mounting flange on a 7000 lbs axle?

Bolt the 5-hole flange to the axle using the supplied backing plates, then wire the DC12V magnet drawing 2.8 to 4.2A; the step often missed is setting the initial shoe-to-drum gap so the self-adjusting mechanism can engage from the first stop.

What maintenance or replacement will the brake pads need after installation?

The asbestos-free semi-metallic pads measuring 1.97" x 0.19" wear to the 30,000 km rated lifespan; plan to inspect thickness at each service and replace the full set once material reaches minimum spec.

What limit appears first during sustained braking on a 7000 lbs trailer?

Continuous stops build heat in the 12" x 2" drums faster than the SPHC + Q235 backing plates can dissipate it, so fade from the 0.48 friction coefficient shows up before the 600N magnet force drops.
