PowerStop JBR1129SCR Disc Brake Rotor - Front

Coated front brake rotor replacement

PowerStop JBR1129SCR is a direct bolt-on disc brake rotor built to match original equipment dimensions and vane count. It is a vented, full cast rotor with a silver epoxy coating on corrosion-prone areas to help preserve appearance behind alloy wheels.

Compatible with Nissan Quest, INFINITI Q45, and INFINITI M45 front brake applications, this rotor is made for drivers replacing a worn or rusted OE-style disc brake rotor with a part that follows factory specifications.

Key features

• Part number JBR1129SCR for easy identification and ordering.
• Partially coated design protects the hat, outer edge, and vanes from corrosion.
• Vented, full cast construction with a smooth braking surface.
• Mill balanced to support consistent operation.
• Built to match OE weight and vane count for proper fitment.

Detailed fitment and function

Fits 2011-2017 Nissan Quest, front; fits 2004-2009 Nissan Quest, front; fits 2002-2006 INFINITI Q45, front; and fits 2003-2004 INFINITI M45, front. The JBR1129SCR is a practical replacement for vehicles that need a front disc brake rotor with the same general size and mounting pattern as the original part. Its 11.40-inch outside diameter, 5-lug pattern, and 114.30 mm bolt circle support correct application matching.

This rotor is intended for buyers looking for a coated brake rotor that helps resist visible rust in exposed areas while maintaining OE-style performance characteristics. The coated hat and edge are especially useful on vehicles with open-wheel designs where rotor appearance is visible.

What this rotor helps address

• Brake rotor wear that can reduce braking smoothness.
• Surface rust on exposed rotor areas.
• Noise or vibration caused by an uneven or worn rotor.
• Fitment issues from using a rotor that does not match OE dimensions.
• Visible corrosion behind alloy wheels.

Installation notes and quality

Verify rotor diameter, bolt circle, and vented construction before installation. Clean the hub mounting surface and confirm the brake system is in proper condition before fitting the new rotor. This part cross-references Nissan OE numbers 40206-1JR1A and 40206-3WS1B for the same application.

PowerStop designs this rotor to align with original equipment performance and specifications, including weight and vane count, for confirmed fitment on the listed Nissan Quest, INFINITI Q45, and INFINITI M45 applications.
