Detailed Description

Brake calipers depend on sealing components that keep fluid pressure controlled while allowing the piston and seals to return properly after braking. Carlson 41218 is built for that service need, with components selected to support the caliper’s apply and release cycle. This makes it a direct-fit repair option for rear brake service on 2003-2006 Ford Expedition and 2003-2006 Lincoln Navigator models, plus the listed 2003 front disc applications.

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

What It Helps Address

• Brake fluid seepage at the caliper seal area
• Sticking or slow-return caliper piston movement
• Uneven brake response caused by worn sealing components
• Noise or drag related to deteriorated caliper boots
• Service needs on rear calipers for Ford Expedition and Lincoln Navigator

Installation Notes and Tips

Confirm caliper style and axle position before service. Clean the caliper bore and piston surfaces thoroughly, inspect for scoring or corrosion, and replace any damaged sealing surfaces before reassembly. Verify the vehicle-specific notes for 2003 front applications, including the listed cutoff and disc configuration details, to ensure correct part selection.

Quality Assurance

Carlson brake service components are engineered around the caliper’s sealing function so the repaired unit can operate as designed during braking and release. Use this kit when servicing the specified Ford Expedition and Lincoln Navigator brake calipers, including applications identified by part number 41218.
