Product Details

Raybestos 5042R is part of the R-Line product line, which covers everyday brake service applications with OE-style dimensional accuracy. This front brake rotor uses a solid, conventional design and the listed measurements to support proper rotor fitment on the specified Buick Century, Chevrolet Celebrity, Oldsmobile Cutlass Ciera, and Pontiac 6000 platforms, along with related compact GM models from the 1980-1989 range.

This part cross-references Monroe Shocks & Struts (e.g., 5548) for the same application.

What This Rotor Helps Address

  • Brake pulsation caused by rotor wear or thickness variation
  • Reduced braking performance from a worn front rotor
  • Noise or vibration related to rotor surface condition
  • Service replacement needs on front disc brake systems
  • Dimensional mismatch when replacing an OE-style rotor

Installation Notes

Verify rotor diameter, center hole diameter, bolt circle, and nominal thickness against the vehicle before installation. Clean the hub mounting surface, inspect pads and caliper components, and confirm the rotor seats flat on the hub. After installation, follow the vehicle manufacturer’s brake bedding procedure and recheck brake pedal feel and rotor runout as part of the final inspection.

Quality Assurance

Raybestos R-Line parts are built for service replacement applications with attention to fit and dimensional consistency. The 5042R is identified by Raybestos part number 5042R and is cataloged for the confirmed front fitments listed above.
