Cardone 18-4857 is remanufactured to OE standards and pressure-tested for consistent brake performance. It is built with brand-new premium components, including durable pistons, new seals, and service hardware, to restore proper hydraulic operation on the front left brake corner of the vehicle.

Common Repair Uses

• Uneven braking or brake pull during stops
• Sticking or seized front left caliper piston
• Brake drag caused by worn internal seals
• Low brake pedal concerns tied to caliper hydraulic issues

Installation Notes

Verify vehicle build date before ordering: this part fits 2003 Ford Expedition and 2003 Lincoln Navigator front left applications before 07/15/2002. Use the brake fluid specified by the original equipment manufacturer, and replace fluid from a sealed container only. Floating caliper mounting pins use silicone grease, and the system should be bled carefully after installation to remove air.

Because this is an unloaded caliper, pads are not included. Confirm piston material, caliper side, and bracket requirements against the vehicle before installation to ensure the correct repair.

Quality Assurance

Each Cardone remanufactured caliper is pressure-tested and assembled with new premium components to meet rigorous performance standards. The remanufacturing process also reduces energy and raw material use compared with producing a new part.
