Overview
PowerStop JBR1745SCR is a front disc brake rotor built as a direct bolt-on replacement for original equipment. It is engineered for drivers who want OE-style fitment, corrosion protection, and a clean appearance behind alloy wheels.
Key Features
- Partially coated rotor with silver epoxy on corrosion-prone areas
- Coated hat, outer edge, and vanes help resist rust
- Full cast, vented construction with a smooth surface
- Mill balanced to support OE-style performance and fit
- Matches original equipment weight and vane count
Detailed Description
This PowerStop coated hat and edge rotor is designed to replace the original front brake rotor with the same general specifications used by the factory part. The vented, full cast design measures 11.69 inches in outside diameter and uses a 5-lug, 114.30 mm bolt circle. The corrosion-resistant coating helps preserve the rotor’s appearance in exposed areas, which is especially useful on Mazda CX-5 and Mazda 6 applications where wheel visibility matters. Part number JBR1745SCR is also referenced as KD45-33-251 for the same application.
PowerStop’s coated rotor line focuses on practical OE replacement features rather than unnecessary changes. JBR1745SCR is built to match original equipment performance targets, including weight and vane count, while the coated finish helps reduce visible rust on the hat and edge. This makes it a straightforward choice for Mazda CX-5 and Mazda 6 front brake service when you want a rotor that installs in place of the factory unit.
What It Is Used For
- Replacing a worn or warped front brake rotor
- Addressing brake pulsation caused by rotor wear
- Restoring braking surface condition after corrosion buildup
- Maintaining a cleaner look behind alloy wheels
- Returning brake system dimensions to OE-style specifications
Installation Notes and Tips
Compatible with 2016-2025 Mazda CX-5, front, and 2020-2021 Mazda 6, front. Verify rotor dimensions, bolt pattern, and brake package details before installation. Clean the hub mounting surface thoroughly and inspect pads and caliper hardware during brake service to help ensure even contact and proper operation.
Quality Assurance
PowerStop designs this rotor to match original equipment performance and specifications, including weight and vane count, for confirmed fitment on listed applications. The coated finish adds corrosion resistance to exposed areas for long-term appearance and service support.
