Inspect rotor for lateral run-out, parallelism and minimum thickness specification. Compare to manufacturers specifications. If rotor is not within specifications, see Step 2.
Failure to clean rust buildup and properly lubricate caliper brackets during brake service is proven to be a major cause of brake noise, premature wear and increased stopping distance.
Take a look at the Wagner Trouble Tracer Chart to help identify disc brake problems and their causes, effects and solutions.
An effective burnish cycle to seat the friction materials into the opposing rotor and drum surfaces requires approximately 200 stops. The 200 stops are consistent with the burnish procedure...
Friction materials are not normally the cause of a noise or vibration. It generally results from rust, distorted or loose components and/or the wearing or weakening of an original part.
As a global leader in braking innovation, Wagner Brake engineers optimize the chamfer shape for each specific brake pad application. These specialized chamfers ensure optimal reduction in brake vibration and noise in all braking conditions.
All Wagner E-Shield rotors come in a Vapor Corrosion Inhibitor (VCI) bag to inhibit rust. Proper cleaning of the new rotor must be done before installing.
