Electric Trailer Brake Kit

The VEVOR electric trailer brake kit fits axles rated to 8000 lbs and uses a 12.25 x 3.375 in drum size. It includes two brake shoes, two shields and a user manual. The assembly weighs 36.6 lbs and is built from SPHC and Q235 steel for structural rigidity.

12 V DC Electromagnetic Actuation

The brake operates on a 12 V DC supply drawing between 2.8 and 4.2 A and develops 600 N of magnetic force. Mounting uses a 4-bolt flange on a 5 in PCD with 7/16-20UNF threads 0.8 in long. The electromagnet diameter is 12 in and the overall brake dimensions are 12.28 x 4.33 in.

Rated Capacity and Wear Limits

The friction material measures 50 x 4.7 mm with a coefficient of 0.48 and a quoted service life of 30000 km. It is designed for trailers up to 3629 kg gross weight. Buyers needing higher axle ratings or hydraulic actuation will need a different system.

Questions about this item

How do I choose between the 12.25 x 3.375 in and 12.28 x 4.33 in brake dimensions listed?

The 12.25 x 3.375 in figure is the nominal brake size for the 8000 lbs axle rating. The 12.28 x 4.33 in measurement is the overall unit footprint including the flange and housing.

What does the 8000 lbs axle rating mean when the kit is installed on a trailer?

It indicates the maximum axle capacity these brakes are designed to stop. The kit includes two shoes for one wheel and draws 2.8 - 4.2 A at DC12V to produce 600 N magnetic force.

What does the 4-bolt PCD 5 inches flange pattern cap in practice?

The four 7/16-20UNF bolts on a 125 mm pitch circle diameter fix the assembly to a matching hub. The pattern limits fitment to axles drilled for that exact bolt circle and thread.
