Carlson Disc Brake Caliper Piston P/N:7130

Turn pedal pressure into rear-brake clamping force with the Carlson Disc Brake Caliper Piston, MPN 7130. This is the hydraulic piston that rides inside the rear brake caliper, translating brake-fluid pressure into the force that presses the pad against the rotor each time you apply the brakes. It installs as a direct-fit replacement piston for the rear calipers on the 1999-2003 Lexus RX300 (All engines).

• Rear caliper application: designed to replace the piston in the rear disc brake caliper on the listed Lexus RX300 applications.
• Core hydraulic component: transfers hydraulic pressure to clamp the brake pad against the rotor, then relaxes as that pressure is released.
• Sold individually: the RX300 uses two (one per rear caliper) — order 2 for a complete rear replacement, and service both sides together for balanced braking.

Over many miles a caliper piston can corrode, pit, or stick in its bore. Signs it may need replacing include a rear brake that drags, uneven or accelerated pad wear, or fluid seeping past the piston seal. If a worn piston is the cause of these symptoms, replacing it helps return proper piston travel within the caliper; diagnose the cause first, since these symptoms can have other sources. Replace the caliper seals as directed by the vehicle service procedure. Manufacturer part number 7130.
