It Took Our Engineers to Solve This Long-Time Rust-Jacking Problem

In order to develop a real-world solution, our brake engineers recreated actual road conditions. Unlike most testing, we first took lined brake shoes and subjected them to brake applications on a dynamometer – before we subjected them to a salt spray test. In this approach, brake shoes reach the salt spray test with wear and tear that more closely approximates actual highway results.

In our ASTM B-117 Salt Spray Test*, brake shoes were sprayed with a bath made of modern anti-icing road solvents and saltwater for 408 hours. We observed how rust forms on brake shoe tables and tested the corrosion resistance of countless paints and coatings.

Results after salt spray test.

Of all the brake shoes and coatings tested, we found that our PlatinumShield™ coating does the best job of protecting the shoe table by preventing micro-abrasions, so rust-jacking simply does not occur during the expected life of the brake shoe.
