12-inch Off-Road Battery-Powered Handbrake System

Key Features

The field version features enhanced sealing structure for dust, water, and sediment resistance.
Battery-powered electronic handbrake ensures stable parking on steep off-road slopes without skidding
Seismic reinforcement assembly ensures enhanced structural stability under off-road bumpy conditions
12-inch large brake drum for enhanced off-road heavy-load braking performance

Product Overview

The 12-inch off-road battery-powered handbrake brake is specifically designed for trail towing, off-road RVs, and trailers operating on un paved surfaces such as deserts, gravel, or muddy terrain. It features a reinforced structure resistant to dust, water, and vibration; combines a battery-powered electronic parking brake with an electromagnetic service brake to withstand road bumps, mud immersion, and sand erosion, while offering enhanced impact resistance—making it ideal for hardcore off-road towing modifications.

Maintain (Service)

After crossing rivers, water obstacles, or muddy terrain, clean the external mud and debris from the brakes and inspect the seals as well as the waterproofing of the wiring harnesses.
Conduct quarterly inspections of brake shoe wear, electronic handbrake performance, and bearing seal condition.
Recheck the wheel hub nut tightening torque after driving over rough or bumpy road sections
Lubricate the bearings regularly and inspect the waterproofing and shock resistance of the electrical control circuits.
