Product Details

This Cardone unloaded caliper w/bracket is built for drivers servicing the front left brake on a 2003 Ford Expedition or 2003 Lincoln Navigator before 07/15/2002. The Cardone 18-B4857 remanufactured brake caliper uses brand-new premium components, including seals, bleeder screws, and hardware, to support dependable braking and a clean installation. The included bracket applies to this part number and application, and the unit is pressure-tested before release.

Cardone’s remanufacturing process reuses the core housing while replacing wear items with new components, reducing raw material and energy use versus manufacturing a new part. This part cross-references Ford 2L1Z2B121BA for the same application.

Common Brake Issues This Part Can Address

• Brake fluid leakage at the caliper
• Uneven braking at the front left wheel
• Sticking or dragging caliper operation
• Corrosion-related caliper performance loss
