PowerStop S7170 Disc Brake Caliper Set - Front

PowerStop Front Brake Calipers for Sonata and Optima

PowerStop S7170 front brake calipers are remanufactured disc brake caliper assemblies built for direct replacement on select Hyundai Sonata and Kia Optima applications. Finished in high-heat red powder coat, they add corrosion resistance and a clean appearance behind stock or custom wheels.

Key Features

• Front floating disc brake caliper set with mounting bracket included
• Remanufactured cast iron caliper body with steel piston
• 61.00 mm piston diameter
• Red electrostatic high-temperature powder-coated finish
• Caliper slides included for service-ready installation
• Pressure tested to verify piston operation and check for leaks
• Assembled with new pistons, seals, slide pins where applicable, dust boots, bleeder screws, and stainless steel brake pad abutment clips
• High-temperature EPDM rubber dust boots and silicone lubricant used for smoother operation in demanding conditions

Product Details

PowerStop Performance Brake Calipers are remanufactured in Chicago, IL and built to replace the original front calipers on 2015-2019 Hyundai Sonata and 2016-2019 Kia Optima models. The S7170 caliper set is engineered for direct bolt-on replacement, making it a practical choice for drivers servicing worn or leaking front brake calipers while maintaining OE-style fitment and braking function. The red powder-coated finish helps resist rust and corrosion, while the floating caliper design supports consistent pad contact during braking.

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

What This Part Helps Address

• Front brake caliper leakage
• Sticking or uneven caliper piston movement
• Corrosion on the caliper housing
• Brake drag caused by worn slide components
• Reduced braking performance from a damaged original caliper

Installation Notes

Fits 2015-2019 Hyundai Sonata, front. Fits 2015-2019 Kia Optima, front. Verify brake hose routing, bracket alignment, and piston operation before returning the vehicle to service. Bleed the hydraulic system after installation and inspect pad wear, rotor condition, and slide movement during brake service.

Quality Assurance

Each PowerStop S7170 caliper is 100% pressure tested to confirm piston operation and help prevent leaks. The remanufacturing process includes new internal service components and inspection for quality and safety before release.
