Product Details
Wagner premium brake rotors are engineered with a focus on braking performance, corrosion resistance, and ease of installation. This BD126243E rear rotor is a direct replacement style part for select rear brake applications, including 2003-2006 Saab 9-3, 2007-2010 Saab 9-3, 2011 Saab 9-3, 2007-2008 Cadillac BLS, and 2010 Porsche Cayenne.

For service work on Saab 9-3 rear brakes, Cadillac BLS rear brakes, or a Porsche Cayenne rear rotor replacement, the BD126243E provides the dimensions and construction needed for a proper fit.
Common Reasons to Replace
- Brake pulsation from rotor wear or thickness variation
- Rust buildup on the braking surface or exposed rotor areas
- Noise during braking caused by uneven rotor condition
- Reduced braking consistency from heat cycling and surface wear
- Service replacement for a rear rotor that no longer meets specification
Installation Notes and Tips
Verify rotor diameter, thickness, and rear position before installation. This rotor is listed for solid rear rotor applications with 278 mm diameter fitment notes on select vehicles, so confirm the vehicle-specific brake package before ordering. Clean the hub mounting surface thoroughly and inspect pads, caliper hardware, and brake fluid condition during rotor service. Pairing Wagner rotors with Wagner brake pads supports matched brake system service.
Quality Assurance
Wagner Brake designs premium rotors with corrosion resistance and installation ease in mind. The BD126243E uses a rust-resistant coating and full cast construction to support dependable service in the listed applications.
