Maintenance Parts for Longzhong 22.5-inch Brake of Jinlong Higer
Bus - Self-adjusting Mechanism
Product Description
Ensure the ultimate braking safety and efficiency of your fleet
with the Automatic Slack Adjuster from Nanjing Dingguan Auto Parts
Co., Ltd. This critical repair component is specifically engineered
for 22.5-inch brake systems, widely used in popular bus models from
leading manufacturers such as King Long and Higer, and is a perfect replacement for Longzhong brake assemblies.
An Automatic Slack Adjuster (ASA) is a vital safety mechanism that

shoes and the drum. By consistently compensating for brake lining
wear, it guarantees immediate, reliable, and balanced braking
performance every time the pedal is pressed.

reducing braking distances and improving vehicle control, which is
paramount for passenger safety.
- Reduced Maintenance Costs: Eliminates the need for frequent and time-consuming manual brake
adjustments, minimizing vehicle downtime and lowering labor costs.
- Precision Compatibility: Designed as a direct-fit replacement for 22.5" Longzhong brake
systems on King Long and Higer buses, ensuring seamless
installation and flawless operation.
- Superior Durability: Constructed from high-strength, heat-treated steel, our slack
adjusters are built to withstand the rigorous demands of heavy-duty
commercial use, ensuring long-lasting performance.
