Rear coated brake rotor

PowerStop JBR1145SCR is a direct bolt-on rear disc brake rotor built to match original equipment dimensions and performance targets. It is compatible with Lexus ES350, Toyota Avalon, and Toyota Camry rear brake applications, with a coated finish that helps resist corrosion on exposed surfaces.

Key features

  • Partially coated design protects the hat, outer edge, and vanes from corrosion.
  • Mill-balanced full cast construction supports consistent brake operation.
  • Solid rotor design with a smooth surface for OE-style replacement.
  • Matches original equipment weight and vane count for proper fitment.
  • Compatible with rear brake applications for Lexus ES350, Toyota Avalon, and Toyota Camry.

Detailed description

The PowerStop JBR1145SCR rear rotor is engineered as an OE-style replacement for drivers who want a direct-fit brake rotor with corrosion protection in the areas most exposed to the elements. The silver epoxy coating on the hat, outer edge, and vanes helps preserve appearance behind alloy wheels while the full cast, mill-balanced construction is built to maintain the original braking characteristics expected from the factory setup. This rotor is a practical choice for Lexus ES350 rear brake service, Toyota Avalon rear brake service, and Toyota Camry rear brake service.

This part cross-references Toyota 42431-06110 and 42431-33130 for the same application.

What it is used for

  • Replacing a worn rear brake rotor with an OE-style direct-fit part.
  • Addressing rotor corrosion on exposed mounting and ventilation surfaces.
  • Restoring smooth braking performance after rotor wear or scoring.
  • Maintaining proper brake geometry when factory dimensions are required.

Installation notes and tips

Verify rotor diameter, bolt pattern, and thickness before installation. Clean the hub mounting surface and inspect pads and caliper components for wear before reassembly. Because this rotor is a direct bolt-on replacement, it is intended to install using factory-style mounting points on the listed rear applications.

Quality assurance

PowerStop designs this rotor to match original equipment specifications, including weight and vane count, to support proper fitment and consistent performance.
