Detailed Description

Brake performance depends on every hydraulic component working together, and the caliper piston is a critical part of that system. Carlson 7804 is designed for rear disc brake applications and supports the pressure transfer needed for consistent pad engagement at the rotor. This part is a practical choice for servicing rear brake hydraulics on Ford Ranger, Ford Explorer, and Mercury Mountaineer models listed in the fitment data. This part number, 7804, is a useful reference when matching the correct rear caliper piston for these vehicles.

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

What It Helps Fix

  • Brake fluid pressure not transferring properly at the rear caliper
  • Uneven rear pad contact against the rotor
  • Rear brake drag caused by a worn or damaged piston surface
  • Reduced braking response from caliper hydraulic wear
  • Service issues on rear disc brake systems in Ford Ranger, Ford Explorer, and Mercury Mountaineer applications

Installation Notes and Tips

Confirm rear brake configuration and match the piston to the caliper design before installation. Inspect the caliper bore, seals, and surrounding hydraulic components during service, and verify clean, smooth movement after assembly. For fitment, use the listed vehicle application details: Fits 1998-2002 Ford Ranger, rear; Fits 1995-2001 Ford Explorer, rear; Fits 1997-2001 Mercury Mountaineer, rear.
