Supply SINOTRUK HOWO Heavy Duty Truck Parts Jiefang Dongfeng 153 Front Right Brake Floor 3501N-026

The 3501N-026 Front Brake Backing Plate is a core structural component of the drum brake system used in the front axle assemblies of medium- and heavy-duty commercial vehicles. This backing plate serves as the mounting foundation for critical braking elements, including brake shoes, wheel cylinders (brake cams or slack adjusters in S-cam systems), return springs, hold-down springs, and automatic adjusters.

Engineered to meet original equipment (OE) specifications, this part ensures precise alignment and stable operation of the entire brake mechanism under high thermal and mechanical loads. Commonly installed on trucks and buses manufactured by Dongfeng, Foton, and other Chinese commercial vehicle brands, the 3501N-026 is designed for durability, heat dissipation, and resistance to corrosion in demanding operating environments.
