Rear Brake Caliper Piston for 1999-2003 Lexus RX300 - GRC 7130

Help restore firm, even brake actuation at the rear axle with the Carlson Rear Disc Brake Caliper Piston 7130. It's a direct-fit replacement for the 1999-2003 Lexus RX300, where the listed application uses two of this piston. The piston is the moving component inside the caliper: when you press the brake pedal, hydraulic pressure acts on the piston, driving it outward so it forces the brake pad against the rotor to slow the wheel.

• Rear caliper application: cataloged for the rear position on the 1999-2003 Lexus RX300.
• Core hydraulic component: converts brake-line hydraulic pressure into the clamping force that presses the pad to the rotor.
• Sold individually: the listed application uses two of this piston.

Signs the original piston may need replacing include a seized or sticky piston, fluid weeping past the piston seal, uneven or dragging rear pad wear, or corrosion and pitting on the piston surface. If a worn or corroded piston is the cause of your rear braking issue, replacing it with this Carlson piston addresses that component. Diagnose the caliper and hydraulic system before ordering to confirm the piston is the source of the problem.
