PowerStop JBR1921XPR Disc Brake Rotor Set - Rear

Rear Brake Rotor Upgrade for Toyota Trucks and SUV

PowerStop JBR1921XPR is a rear drilled and slotted brake rotor set built for direct OE fitment on select Toyota applications. It combines cross-drilled cooling, slotting for surface cleaning, and zinc dichromate plating to help resist rust while maintaining consistent brake contact.

Key Features

• Drilled and slotted surface helps move heat, dust, gas, and moisture away from the rotor face
• Silver zinc dichromate coating resists rust and corrosion
• Vented full cast construction for performance-focused braking
• Direct OE fit with no special modifications needed
• Rear rotor application for Toyota Sequoia, Tacoma, and Tundra
• Part number JBR1921XPR for easy identification

Product Details

The Power Stop rear drilled, slotted and zinc plated rotor line is built for drivers who want a bolt-on brake rotor upgrade with OE-style fitment and performance-oriented surface design. The JBR1921XPR uses a slotted X drilled pattern to help maintain a cleaner friction surface, while the zinc plated finish adds corrosion resistance for long-term appearance and durability. With a 13.20-inch outside diameter, 20.00 mm nominal thickness, 18.60 mm discard thickness, 5.50-inch bolt circle, and 6 lug holes, this rotor is engineered for the rear axle on 2022-2026 Toyota Tundra, 2023-2026 Toyota Sequoia, and 2024-2026 Toyota Tacoma. This part cross-references Toyota 42431-0C020 and 42431-04090 for the same application.

Common Brake Issues It Can Address

• Brake fade during repeated stops or heavier-duty use
• Surface rust on exposed rotor faces
• Dust and moisture buildup on the braking surface
• Uneven rotor appearance from corrosion exposure
• Loss of consistent rear brake contact from worn OE rotors

Installation Notes and Tips

Compatible With 2023-2026 Toyota Sequoia, rear; 2024-2026 Toyota Tacoma, rear; and 2022-2026 Toyota Tundra, rear. Verify rotor diameter, thickness, bolt circle, and lug count before installation. Clean the rotor surface before service and follow the vehicle manufacturer’s brake bedding procedure after installation. JBR1921XPR is a direct-fit rear rotor replacement, so no special modifications are required when used on the listed applications.

Quality Assurance

PowerStop manufactures this rotor with a rust-resistant zinc dichromate coating and precision drilled-and-slotted machining for consistent fit and finish. The design follows OE-style dimensions for the listed Toyota rear brake applications.
