10″ 3.5K electric brake self adjusting

Key Features

Automatic gap adjustment, eliminating the need for frequent manual brake adjustment
10-inch industry-standard size with high versatility
Long-lasting anti-corrosion technology with excellent durability for outdoor applications
Standardized modular assemblies for hassle-free maintenance

Product Overview

The 10-inch American-style self-adjusting drum brake is the standard braking assembly for 3,500-pound RVs, light-duty cargo trailers, and agricultural trailers. Equipped with an automatic clearance adjustment mechanism that automatically compensates for brake clearance wear during operation, it ensures consistent and stable braking performance over extended use. Featuring an electromagnetic parking brake design, a rust-and corrosion-resistant housing, and standardized construction, it is suitable for both regular paved road conditions and mild outdoor towing scenarios.
