Carlson Disc Brake Caliper Piston P/N:7855

$14.99

Description

Keep hydraulic pressure doing its job inside the rear brake with the Carlson disc brake caliper piston (P/N 7855), a direct-fit replacement for the 2004-2008 Chrysler Pacifica. The caliper piston uses brake fluid pressure to force the brake pads against the rotor — the essential hydraulic step that lets the caliper clamp and slow the wheel.

Hydraulic function: Transfers brake fluid pressure to push the pads against the rotor for stopping.
Corrosion resistant: Built to resist corrosion against harsh road conditions.
OE-quality: Matches Original Equipment (OE) quality specifications.
Service smart: Brakes work as a system — industry brake-service experts agree that when the friction material is ready to be replaced, the hardware usually is too.

This is a rear-caliper piston for the listed application. A worn or corroded original piston can drag, stick, or seize, causing uneven pad wear or a spongy pedal — if the piston is the cause, this replaces it. Sold individually; it is best practice to service both sides of the axle together for even, balanced braking.
