The problem
Cracks may be present in the brake spider. These cracks could eventually cause the brake spider to fail. This could allow separation of that portion of the brake spider that retains the brake camshaft, the brake chamber, and the brake chamber bracket from the foundation brake assembly. Brake pull in the direction opposite the affected wheel location or wheel lock-up on the affected wheel could occur.
The fix
The dealer will inspect and modify the affected brake spiders, free of charge.
