Carlson 7645 Disc Brake Caliper Piston

Carlson 7645 is a steel replacement disc brake caliper piston for front brake applications. It is built for vehicles that use hydraulic caliper operation, where brake fluid pressure pushes the piston to clamp the pads against the rotor.

Key Features

  • Steel replacement caliper piston for front disc brake systems
  • Supports hydraulic brake pressure transfer at the caliper
  • Direct-fit application coverage for select Chrysler, Dodge, and Plymouth models
  • Fits D220, D222, and D170 brake configurations listed in the application data
  • Carlson part number 7645 for catalog and service identification

Application Details

This Carlson 7645 caliper piston is used in front brake service on select 1981-1989 Chrysler, Dodge, and Plymouth vehicles. Fitment includes Chrysler Shadow, Dodge Aries, Plymouth Reliant, and related front disc brake applications, including models noted with standard brake, heavy-duty brake, and wear-sensor exceptions. For buyers searching for a front disc brake caliper piston for a 1983-1987 Dodge Aries or a 1984-1988 Chrysler Daytona, this part number 7645 matches the listed brake configurations.

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

What It Helps Address

  • Brake piston wear or scoring in the front caliper
  • Loss of proper hydraulic force at the caliper
  • Poor pad-to-rotor contact during braking
  • Service needs on D220, D222, and D170 front disc brake setups
  • Replacement during caliper rebuild or brake hydraulic repair

Installation Notes

Verify the caliper code, brake type, and any wear-sensor notes before installation. Confirm the vehicle year, make, model, and front position against the application list for Carlson 7645. Clean the caliper bore thoroughly and inspect related brake components for wear before reassembly.

Quality Assurance

Carlson manufactures brake hardware and hydraulic service parts for repair applications. Part number 7645 is listed for specific front brake fitments on Chrysler, Dodge, and Plymouth vehicles from 1981-1989.
