10″ 3.5K electric brake

Key Features

Manual adjustable clearance with controllable braking force
Standard 10-inch American size with high versatility
Dual-layer anti-corrosion technology for exceptional durability in outdoor environments
Simple and robust structure with low maintenance costs

Product Overview

The 10-inch American-style manually adjustable drum brake is designed for 3,500-pound class light recreational RVs, agricultural trailers, and light freight trailers. It features a standard 10-inch brake drum with manually adjustable brake shoes, allowing precise adjustment of braking clearance and providing controllable braking force. With a robust and reliable structure and a corrosion-resistant housing, it is ideal for outdoor towing conditions such as wilderness, humid environments, and construction sites, making it the classic braking assembly for traditional American-style light trailers.
