Product Details

The PowerStop brake caliper line is aimed at drivers who want OE-style fitment with performance-focused finishing. Part number S6456 is remanufactured with new pistons, seals, dust boots, bleeder screws, stainless steel brake pad abutment clips, and slide pins where applicable. High-temperature EPDM rubber dust boots and premium silicone lubricant are used to support smooth caliper movement in demanding conditions. The red finish is easy to clean and adds a visible performance look on Hyundai Sonata and Kia Optima rear brake setups.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Brake Issues It Can Address

• Rear caliper sticking or uneven brake release
• Brake fluid leaks from worn piston seals or bleeder components
• Corrosion on the caliper body or bracket
• Reduced braking consistency from worn internal components
• Faded appearance behind open-style wheels

Installation Notes

Verify rear fitment by year, make, model, and position before installation. Transfer or replace brake pads and related wear items as needed, and bleed the brake system after caliper replacement. Confirm slide movement and piston operation during installation to ensure proper rear brake function on 2011-2015 Hyundai Sonata and 2011-2015 Kia Optima vehicles.

Quality Assurance

Each PowerStop S6456 caliper is pressure tested to verify piston operation and check for leaks before release. The remanufacturing process and component replacement standards are used to support consistent fit, finish, and brake system reliability.
