Carlson Disc Brake Caliper Piston P/N:7051

Keep your front disc brakes clamping evenly with the Carlson Disc Brake Caliper Piston (P/N 7051). It's a direct-fit replacement for the front brake calipers on the 2019-2020 Hyundai Santa Fe (all engines). Inside the caliper, this piston is what turns brake-fluid pressure into stopping force — when you press the pedal, it slides out of its bore and pushes the brake pad against the rotor, then releases as pressure drops.

• Front application: cataloged for the front disc brake calipers of the listed vehicle.
• Correct quantity: the listed application uses two pistons per vehicle — order 2 for a complete front-axle job.
• Mechanical role: converts hydraulic brake-fluid pressure into the clamping force that presses the pad to the rotor, and retracts as pressure releases.
• Service part: designed to replace a piston that has seized, corroded, or begun to leak past its seal.

Signs the original piston may need replacing include a caliper that sticks or drags, uneven pad wear, or fluid seeping past the seal. If a failed piston is the cause, replacing it — along with any seals and hardware called for by the service procedure — helps return the caliper to normal operation; diagnose the underlying cause before replacing brake components. Best practice is to service both sides of the axle together for balanced braking. Manufacturer part number 7051.
