The new RustGard UV brake shoe coating from Carlisle/Altec solves the problem of rust-jacking and premature truck brake lining failure due to rusting brake shoes. Rust-jacking is caused by corrosive materials sprayed on highways to address slippery road conditions, typically magnesium chloride, calcium chloride, and road salt.

RustGard UV coating applied to Carlisle/Altec remanufactured brake shoes protects against rust-jacking and maximizes brake lining life. To validate RustGard's performance, Carlisle conducted testing in accordance with ASTM B-117, salt spray test. These tests indicate that brake shoes without linings and coated with industry-standard paint had 50% surface rusting after 24 hours of exposure, compared with RustGard-coated/painted shoes, which had less than 10% surface rusting after 250 hours of exposure.

Tests conducted on brake shoes with linings yielded similar results. Shoes with industry-standard paint coating had 50% surface rusting with deep pitting after 170 hours of exposure, whereas RustGard-coated/painted shoes had less than 10% surface rusting after 1,450 hours of exposure.

More testing showed that RustGard withstands temperatures up to 500° F for six hours without affecting performance. RustGard also passed the 100 MEK (methyl ethyl keytone) double resistance chemical test.
