Carlson 7903 Disc Brake Caliper Piston - Front

Carlson 7903 Disc Brake Caliper Piston

Carlson 7903 is a front disc brake caliper piston built for brake hydraulic service where fluid pressure must translate into pad clamping force at the rotor. It is a direct-fit service part for select Jeep Cherokee, Chrysler 200, and Dodge Dart front brake applications.

Key Features

Detailed Description

The Carlson 7903 caliper piston is part of the brake hydraulic system and helps restore proper caliper operation when the original piston is worn, damaged, or no longer sealing correctly. In front brake service, the piston must respond smoothly to hydraulic pressure so the pads can clamp the rotor with consistent force. This part number is listed for 2021 Jeep Cherokee front brake code BRF single piston calipers, 2017-2019 Jeep Cherokee front except heavy duty brakes, 2015-2017 Chrysler 200 front except heavy duty brakes, and 2013-2016 Dodge Dart front applications. Carlson 7903 is also a relevant search match for drivers looking for a front brake caliper piston for Jeep Cherokee, Chrysler 200, or Dodge Dart service.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Brake fluid pressure not translating into proper pad movement
• Uneven or inconsistent front brake application
• Caliper piston wear or surface damage
• Brake service on front disc brake hydraulic components
• Fitment-specific replacement needs for Jeep Cherokee, Chrysler 200, and Dodge Dart

Installation Notes and Tips

Verify caliper style, brake code, and notes before installation. Confirm the vehicle is one of the listed front applications for Carlson 7903, including the specified Cherokee, 200, or Dart configurations. Inspect the caliper bore, seals, and brake fluid condition during service, and follow the vehicle manufacturer’s brake bleeding and torque procedures after assembly.

Quality Assurance

Brakes work as a system, and Carlson positions this piston as a service part for restoring proper hydraulic caliper function in the listed applications. Use the confirmed fitment details above to match the correct front brake configuration before installation.
