Ken-Tool's slack adjusting tools are designed for adjusting drum air brake linkage to remove slack on trucks and trailers.

The tools are made to fit Bendix, Haldex and Meritor air braking systems — one for each manufacturer’s design. They feature tool-grade steel and an offset, reversible ratchet design and are available separately.

The two-piece Meritor Automatic Slack Adjuster Set features a 5/16-inch double square ratchet and a tool to secure the brake shaft from turning during tightening and loosening of the adjustment nut. With heavy-duty molded resin handles, each tool weighs 10.4 ounces, is 12 inches long, and is priced at $70.95 MSRP for the set. 

The Haldex Slack Adjuster Tool uses a 7/16-inch double offset square ratchet, weighs 10.4 ounces, is 14.5 inches long, and is priced at $33.99 MSRP. 

The Bendix Slack Adjuster Tool uses a 9/16-inch double offset square ratchet, weighs 1 pound, is 14.5 inches long, and is priced at $51.50 MSRP. The Haldex and Bendix tools each have extra-long handles for improved leverage, with slip resistant vinyl hand grips. To reverse direction on the Bendix and Haldex tools, the technician turns the tool over. Each of the part numbers are packaged in polybags with barcoded hang tags for vertical retail display.

Ken-Tool Air Brake Linkage Adjustment Tools all carry a limited lifetime warranty.
