PowerStop JBR751XPR Disc Brake Rotor Set - Rear

Rear Brake Rotor Upgrade for Infiniti

PowerStop JBR751XPR is a rear disc brake rotor set built for direct OE fitment on select Infiniti applications. It combines drilled and slotted rotor surfaces with a zinc-plated finish to support cooler braking, cleaner pad contact, and better corrosion resistance in everyday and demanding driving.

Compatible with 1997-2001 Infiniti Q45 rear and 1993-1997 Infiniti J30 rear, this rotor set is a straightforward replacement for drivers looking for a performance-oriented brake rotor upgrade without special modifications.

Power Stop Rotor Line Details

The Power Stop drilled and slotted rotor line focuses on airflow, surface cleaning, and corrosion protection. Cross-drilled holes help move heat away from the braking surface, while rounded slots clear dust, gas, and moisture to maintain consistent pad-to-rotor contact. Silver zinc dichromate plating adds a rust-resistant layer for long-term appearance and protection.

Detailed Description

PowerStop JBR751XPR is engineered as a rear brake rotor replacement for Infiniti Q45 and Infiniti J30 models listed in the fitment data. The vented, cross-drilled, and slotted design supports heat dissipation and helps maintain a cleaner friction surface during repeated stops. The zinc-plated finish adds protection against rust and corrosion, making it a practical choice for drivers who want a performance-style rotor with OE-style fitment.

This part cross-references Monroe Shocks & Struts 172286 and 182286 for the same application.

What This Rotor Set Helps Address

• Brake fade during repeated or high-temperature stops
• Excess dust, gas, and moisture buildup on the rotor face
• Rust and corrosion on exposed brake rotor surfaces
• Uneven pad contact caused by worn rear rotors
• Reduced braking consistency on Infiniti Q45 and Infiniti J30 rear brake applications

Installation Notes and Tips

Verify rotor dimensions, bolt pattern, and rear position before installation. This rotor set uses a direct OE fit, so no special modifications are needed when installed on the listed Infiniti applications. Inspect pads, calipers, and hub surfaces during service to help ensure proper brake operation and even wear.

Quality Assurance

PowerStop manufactures this rotor line with precision machining, corrosion-resistant plating, and application-specific fitment for the listed vehicles. The part number for this application is JBR751XPR.
