ATC1697 Gunite, Brunner, and Bendix Slack Adjuster Puller 10409

The ATC1697 Slack Adjuster Puller – 10409 is a specialized brake service tool engineered for safe, controlled removal of automatic slack adjusters manufactured by Gunite, Brunner, and Bendix. This puller is designed to engage a variety of slack adjuster styles and guide them off the brake camshaft without damage to the adjuster, cam yoke, or axle components—making it an essential asset for brake maintenance on heavy-duty commercial vehicles.

Automatic slack adjusters are often subjected to corrosion, heavy loading, and extended service cycles that make them difficult to remove by conventional methods. Improvised removal techniques such as hammering, chiseling, or twisting can damage the adjuster body, threads, or brake hardware. The ATC1697’s robust design allows technicians to apply straight, incremental pulling force, minimizing risk and ensuring a professional-grade brake service.

Built from high-strength steel and designed for frequent shop use, the 10409 puller supports efficient brake service in fleet maintenance operations, truck repair shops, and heavy-duty service bays handling Class 6–8 vehicles.
