AZ9981341005 brake shoe tension spring is an elastic spare part of the drum brake system for Sinotruk Howo heavy trucks. It is installed between two brake shoes. After braking action is completed, it pulls the brake shoes back quickly to release the brake drum, restoring the standard braking clearance and preventing dragging brake. Made of high-quality spring steel wire with stress relief treatment, the spring features high elastic limit, good fatigue resistance and stable resilience. It can withstand repeated stretching and vibration under heavy load and frequent braking conditions. Each spring undergoes strict tension test, fatigue cycle test and surface inspection before delivery. It effectively solves brake dragging and abnormal wear of brake lining, ensures sensitive brake release, and extends service life of brake drum and friction lining. It is a common consumable part for wheel brake overhaul. We maintain sufficient inventory and stable bulk supply for repair workshops, fleet operators, auto spare parts dealers and global cross-border export customers.
