Product Details

This Raybestos Specialty - Street Performance rotor is specified for front brake service on select Cadillac CTS, STS, and Seville models. The vented rotor design supports the factory brake configuration used on vehicles with sport suspension or GM Brake Code JL9 applications, and the listed dimensions help ensure proper fitment at the hub and caliper interface. If you are replacing a worn front rotor on a Cadillac CTS front brake system or a Cadillac STS front vented rotor setup, the 580104 matches the published OE-style measurements for these applications.

This part cross-references DuraGo BR55096 and PowerStop AR82103EVC for the same application.

Common Problems This Rotor Can Address

• Brake pulsation caused by rotor wear or thickness variation
• Reduced braking performance from a worn front rotor surface
• Rotor scoring, grooves, or heat checking
• Noise or vibration during front brake operation
• Replacement needs for Cadillac CTS, STS, or Seville front brake service

Installation Notes and Tips

Verify rotor diameter, center hole diameter, bolt circle, and vented construction before installation. This rotor is listed for front position only and for specific Cadillac trim and suspension combinations, including CTS models with FE2 Ride and Handling Suspension or FE3 Sport Suspension and STS models with GM Brake Code JL9. Always confirm the vehicle’s brake code and suspension package against the fitment notes before ordering.

For best results, inspect pads, calipers, and hub surfaces during rotor replacement so the new rotor seats evenly and the brake system can be serviced to the same specification on both sides of the axle.
