What Is Rust-Jacking?

Why is it such a problem? Rust-jacking is caused by corrosive anti-icing highway chemicals – combined with thawing and freezing moisture that penetrates the brake shoe coating and causes rust to build up on the brake shoe table.

As rust builds up, it pushes outward against the brake lining, “jacking” it up between the rivets, until the lining cracks.

Rust-jacking is found most often where intense brake heat cannot dry out the shoe table. Typically, this occurs in front shoes.

Until now, rust-jacking was an industry-wide problem that simply evaded solution. But now the brake engineers at ArvinMeritor have solved this problem with PlatinumShield™ coating.
