Firm up braking response with the Carlson Disc Brake Caliper Piston 7974 — the component that converts hydraulic brake-fluid pressure into the clamping force that presses the brake pads against the rotor to slow the vehicle. It drops in as a direct-fit replacement for the 2007-2010 Kia Rondo [All], which uses two pistons per application, so order 2 for a complete job.
- Steel build: machined from steel and corrosion-resistant to resist rust from harsh road conditions.
- Sized to spec: 2-3/8 in (61 mm) diameter and 1-4/5 in (45.7 mm) height.
- OE-quality: matches Original Equipment (OE) quality specifications.
- Core braking hardware: uses brake-fluid pressure to force the pads against the rotor.
Brakes work as a system, and worn hardware is best refreshed alongside the friction materials. If a scored, seized, or corroded piston is behind a dragging brake, uneven pad wear, or a spongy pedal, replacing it with this piston restores proper hydraulic actuation. Country of origin: China.
