The Part No. DZ90149346041 is a high-performance Automatic Slack Adjuster (ASA) manufactured by Hande Axle (HanDe), specifically engineered for 35-ton heavy-duty and mining-duty rear axles used in China’s off-highway and ultra-heavy-duty trucking sectors. This component plays a vital role in maintaining optimal braking performance on vehicles such as wide-body dump trucks and heavy-haul dumpers operating under extreme conditions — including steep slopes, high loads, dust, mud, and continuous brake cycles.

As a core part of the S-cam drum brake system, this automatic brake adjuster ensures that the clearance between the brake lining and brake drum remains within the ideal range (0.7–1.2 mm), regardless of wear. It eliminates manual adjustment requirements and significantly enhances braking consistency, safety, and reliability across multi-axle configurations commonly found on large mining trucks
