Carlson 7039 Front Brake Caliper Piston

The Carlson 7039 is a front disc brake caliper piston for select Ram ProMaster vans with a 46mm piston and D1540 brake configuration. It is a direct-fit brake hydraulics component for restoring caliper function on compatible Ram ProMaster 1500, 2500, and 3500 models.

Key Features

• Disc brake caliper piston for front brake service
• 46mm piston size for listed applications
• Compatible with D1540 front brake setups
• Application-specific fitment for Ram ProMaster vans
• Carlson part number 7039 for easy identification

Detailed Description

Carlson 7039 is a brake hydraulics replacement part made for front caliper service on 2014-2017 Ram ProMaster 1500, Ram ProMaster 2500, and Ram ProMaster 3500 models. It matches vehicles listed with a 46mm piston and D1540 brake specification, including 2017 Ram ProMaster 2500 and 3500 models except heavy duty brakes. Use Carlson 7039 when replacing a worn or damaged front disc brake caliper piston on the specified Ram ProMaster applications.

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

What It Helps Address

• Brake fluid leakage at the caliper piston area
• Uneven or inconsistent front brake operation
• Sticking caliper piston movement
• Brake drag caused by piston wear or corrosion
• Loss of proper hydraulic response in the front brakes

Installation Notes

Verify the caliper piston diameter, brake package, and front axle application before installation. This part is listed for front position use only and does not apply to heavy duty brake configurations where noted. Confirm the vehicle’s brake code and caliper specification against the existing component before service.

Quality Assurance

Carlson brake hydraulics parts are cataloged for application-specific replacement use. Confirm fitment by year, model, position, and brake specification before ordering.
