PowerStop JBR1320SCR Disc Brake Rotor - Front

Overview

PowerStop JBR1320SCR is a coated 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 smooth braking surface in one part.

Fits 2002-2006 Kia Optima, front and 2003-2005 Hyundai Sonata, front.

Key Features

• Partially coated rotor with silver epoxy on the hat, outer edge, and vanes to resist corrosion.
• Full cast, vented construction with a smooth surface for consistent brake contact.
• Mill balanced to support stable operation and OE-style performance.
• Matches original equipment weight and vane count for proper fitment.
• Part number JBR1320SCR for easy identification and ordering.

Detailed Description

PowerStop JBR1320SCR is part of the brand’s coated hat and edge rotor line, which focuses on OE replacement fit and corrosion resistance. The vented, full cast design uses a silver epoxy coating on exposed areas that are prone to rust, helping preserve appearance behind alloy wheels while maintaining the original equipment dimensions and specifications. This rotor is a practical choice for Kia Optima and Hyundai Sonata brake service where direct replacement fitment matters.

The JBR1320SCR rotor measures 11.02 inches in outside diameter, 1.02 inches nominal thickness, and 0.96 inches discard thickness. It uses a 4.50-inch bolt circle and a 4-lug pattern, with no ABS tone ring included. PowerStop JBR1320SCR is intended for front brake applications on the listed vehicles and cross-references Hyundai/Kia OE numbers 51712-3C100 and 51712-3D300 for the same application.

Common Issues This Rotor Can Address

• Surface rust on the rotor hat and outer edge.
• Brake pulsation caused by worn or out-of-spec rotors.
• Noisy braking from damaged or uneven rotor surfaces.
• Fitment problems when replacing a rotor that must match OE dimensions.
• Visible corrosion behind alloy wheels.

Installation Notes and Quality

Install as a direct bolt-on replacement and verify rotor dimensions, bolt circle, and brake package before service. Clean the hub mounting surface and inspect pads and caliper components during brake work to help maintain even contact. The coated finish is designed to protect corrosion-prone areas while preserving a clean appearance.

PowerStop designs this rotor to match original equipment performance and specifications, including weight and vane count, for guaranteed fitment.
