ATE Coated Rotor Line

ATE Coated Single Pack Rotor products are part of ATE’s premium brake portfolio. ATE, the Continental Automotive Systems brake brand, applies its OE-focused engineering and manufacturing experience to aftermarket brake discs, using first-quality materials and a coated surface to help maintain rotor condition during storage and service.

Detailed Description

SP25142 is a front vented brake rotor for 2000-2009 Saab 9-5 and 2008 Saturn Astra applications. The rotor’s 308 mm diameter, 25 mm nominal thickness, and full cast construction support consistent braking performance, while the rust-resistant coating helps protect the rotor surface before installation and during normal service handling. This part cross-references Brembo 09.9369.11 for the same application.

Common Brake Issues This Rotor Can Address

• Front brake pulsation caused by worn or uneven rotor surfaces
• Brake noise related to rotor wear or surface corrosion
• Reduced braking consistency from rotor thickness loss
• Rust buildup on exposed rotor surfaces during storage or service
• Service replacement needs for Saab 9-5 front brake rotors and Saturn Astra front brake rotors

Installation Notes and Tips

Verify rotor diameter, thickness, bolt pattern, and front position before installation. Clean the rotor friction surface before service to remove any protective residue from packaging or handling. Inspect pads, caliper hardware, and hub condition at the same time so the new rotor seats evenly and the braking system returns to proper operation.

Quality Assurance

ATE brake parts are backed by Continental Automotive Systems’ original equipment manufacturing experience and process engineering. The SP25142 rotor is produced to a higher standard than conventional replacement parts and is specified to meet or exceed North American OEM requirements for the listed fitments.
