Detailed Description
PowerStop’s coated hat and edge rotor line focuses on OE-style replacement parts with corrosion protection where it matters most. This rotor is partially coated to protect the hat, outer edge, and vanes from rust, while the braking surface remains ready for service. The design follows original equipment specifications, including weight and vane count, which supports correct installation on the listed Ford and Volvo front brake applications. If you are replacing worn front rotors on a Ford Focus, Ford C-Max, Volvo C30, or Volvo S40, AR85146SCR provides a direct-fit solution built around the factory dimensions.
Common Replacement Reasons
- Brake pulsation from rotor wear or thickness loss
- Visible rust on the hat, edge, or internal vanes
- Uneven braking feel caused by rotor surface condition
- Noise or vibration during normal braking
- Need for an OE-style front rotor replacement
Installation Notes
Install on the front axle only for the listed applications. Verify rotor diameter, bolt circle, and thickness before installation, especially on 2004 Volvo S40 5-lug models with the 278 mm front rotor specification. Confirm the vehicle’s brake configuration matches the fitment data before service.
Quality Assurance
PowerStop designs this rotor to match original equipment performance and specifications for fitment confidence. The coated surfaces help resist corrosion in exposed areas, while the OE-style construction supports consistent brake service on the specified applications.
