FAW Jiefang Brake Expander Module 3501205CA10 – J6P / JH6 / J7

This is the brake expander module (制动扩张器总成) 3501205CA10 for FAW Jiefang heavy trucks – fits J6P, JH6 and J7 6×4 tractors (China VI emission standard) and lightweight dump trucks. It is the core force-multiplying unit of the foundation brake: compressed air acts on the plunger, and the expander converts this into the mechanical force that presses the brake components against the drum. A worn expander directly reduces braking force even when air pressure reads normal.

Ordering part number: 3501205CA10 (module assembly,制动扩张器)
