Technical Description and Features
This Cardone disc brake caliper features two aluminum pistons measuring 1.59 inches (40.386 mm) in diameter, providing balanced and consistent braking force. The caliper is finished with an oil emulsion coating in gray, which helps resist corrosion and wear. The bleeder port and inlet port sizes are M10x1.0 and M10x1.5 respectively, matching OEM specifications for proper brake fluid flow and maintenance. Installation hardware is included to facilitate mounting, though mounting bolts are not part of the package.

Common Applications and Problem Solving
- Replacement for worn or leaking calipers on Ford Mustang brake systems
- Addresses symptoms such as low brake pedal height caused by air in the brake lines
- Helps resolve uneven braking or vehicle pulling to one side during braking
- Reduces brake squeal related to caliper mounting pin lubrication issues
- Suitable for upgrading from phenolic to aluminum piston calipers where applicable
Installation Notes and Tips
When installing the Cardone 18-B5123 caliper, always use the brake fluid type recommended by the vehicle manufacturer, typically DOT 3 or DOT 4. Apply silicone grease to the floating caliper mounting pins to prevent squealing and ensure smooth caliper movement. Although the hardware kit is included, verify if mounting bolts are required separately for your specific Mustang model. Bleed the brake system thoroughly after installation to remove any air and restore proper pedal feel.
