PowerStop JBR1114SCR Disc Brake Rotor - Rear

Rear coated brake rotor for Mazda 3

PowerStop JBR1114SCR is a direct bolt-on rear brake rotor built to match original equipment dimensions and performance targets. It uses a silver epoxy coating on corrosion-prone areas to help preserve appearance behind alloy wheels.

Key features

• Partially coated rotor with rust-resistant protection on the hat, outer edge, and vanes
• Direct replacement design matched to OE weight and vane count
• Full cast construction with a smooth braking surface
• Mill balanced for consistent operation
• Solid rotor design with a 10.43 in. outside diameter

Detailed fitment and design

This PowerStop rear rotor is engineered for 2004-2013 Mazda 3 applications and follows original equipment specifications for fit and function. The JBR1114SCR uses a solid, full cast design with a 4.50 in. bolt circle and five lug holes, making it a precise replacement for the factory rear brake rotor on the Mazda 3. The coated finish helps resist corrosion in exposed areas while keeping the visible surfaces cleaner behind modern wheels. This part cross-references Mazda OE numbers (e.g. BP4Y-26-251C, BP4Y-26-251D) for the same application.

Common issues this rotor can address

• Rotor surface rust on the hat, edge, or internal vanes
• Brake pulsation caused by worn or uneven rotor surfaces
• Reduced braking consistency from a rotor outside discard thickness
• Visible corrosion behind alloy wheels

Installation notes and tips

Confirm rear brake rotor dimensions, bolt pattern, and discard thickness before installation. The JBR1114SCR is a direct bolt-on replacement, so it should be installed to the same OE specifications used by the factory rotor. Inspect pads and related brake components at the same time to help maintain even braking performance.

Quality assurance

PowerStop designs this rotor to match original equipment performance and specifications, including weight and vane count, for verified fitment on the listed Mazda 3 applications.
