Carlson Disc Brake Caliper Piston P/N:7117

When you press the brake pedal, the caliper piston is the part that turns hydraulic pressure into the clamping force that pushes the pad against the rotor — and the Carlson Disc Brake Caliper Piston 7117 is a direct-fit front replacement for that component. It fits the front brakes of the 2009-2011 Hyundai Genesis, 2013-2016 Hyundai Santa Fe Sport, 2017-2020 Kia Cadenza, and 2014-2015 Kia Sorento (all engines), with each of these applications using two front pistons.

• Core hydraulic component: Moves within the caliper bore under hydraulic pressure from the brake fluid to press the brake pad against the rotor.
• Front position: Cataloged for the front brake position on the listed vehicles.
• Sold individually: Each listed application uses two front caliper pistons — order two to service the axle.
• Signs it may need replacing: A piston that has corroded, seized, or stuck in its bore may show up as a dragging brake, uneven pad wear, or the vehicle pulling to one side while braking.

Because those symptoms can have other causes, diagnose the brake system before replacing. If a worn or stuck front piston is the cause, this drops in as a replacement; replace the pistons on both sides together for balanced braking. Manufacturer part number 7117.
