Product Details

Cardone 18-B4839 is a remanufactured brake caliper for the front left side of the 2003-2004 Ford Mustang. The unloaded caliper w/bracket configuration supports a straightforward brake service on Mustang front brake systems, while the phenolic piston helps manage heat and reduce weight compared with metal piston designs. Each unit is pressure-tested and rebuilt with new premium components, including high-temperature EPDM rubber seals and corrosion-resistant hardware elements where applicable.

This part cross-references Ford 3R3Z2B121CA for the same application. The Cardone brake caliper line focuses on remanufactured OE-style replacements with attention to fit, sealing, and brake system reliability.

Common Brake Issues This Part Addresses

• Brake drag or uneven pad contact at the front left wheel
• Leaking caliper seals or fluid seepage around the piston area
• Corrosion-related caliper sticking or reduced piston movement
• Poor brake pedal response caused by a worn caliper assembly
• Brake pull during stopping from a failing front caliper

Installation Notes

Fits 2003-2004 Ford Mustang, front left. Verify the inlet and bleeder port sizes before installation, and confirm the brake fluid type specified by the vehicle manufacturer. Use fresh, sealed brake fluid and follow proper bleeding procedures after installation. The caliper bracket is included where applicable, and the unit is supplied as an unloaded caliper, so pad selection is handled separately.

Quality Assurance

Cardone remanufactures this caliper to OE-level fit and performance standards, then pressure-tests each unit before release. The process uses new internal components and reduces raw material and energy use compared with manufacturing a new part.
