Cardone 19-B3257 Disc Brake Caliper - Front Left or Front Right

Remanufactured Front Brake Caliper Assembly

Cardone 19-B3257 is a remanufactured disc brake caliper with bracket for the front left or front right brake position, depending on application. It is built for Mercedes-Benz models that use a steel piston design and includes the bracket where applicable for a direct replacement service part.

This unloaded caliper w/bracket is finished in gray with an oil emulsion coating and uses an M10x1.0 bleeder and inlet port size. It is a practical choice for Mercedes-Benz E350, E500, ML350, R350, and related applications where OE-style fit and brake system restoration matter.

Key Features

• Remanufactured Original Equipment-style brake caliper for precise fitment
• Steel piston construction with 2-piston design
• Pressure-tested for consistent brake performance
• New rubber seals use high-temperature EPDM material
• New bleeder screws help support clean bleeding and sealing
• Plastic cap plugs protect brake port threads during installation
• Rust inhibitor treatment helps preserve the OE finish
• Bracket included where applicable

Product Details

Cardone Brake Calipers are remanufactured to meet rigorous quality and performance standards, with brand-new premium components used throughout the rebuild process. The 19-B3257 is supplied as an unloaded caliper w/bracket and is engineered for Mercedes-Benz brake service where the original caliper design calls for a steel piston and OE-style mounting hardware layout. This part cross-references Mercedes-Benz 0034204183 and 1644202383 for the same application.

Common Brake Issues This Part Can Address

• Brake drag caused by a sticking or seized caliper piston
• Uneven braking or pull during stops from caliper wear
• Brake fluid leakage at the caliper body or bleeder area
• Soft or inconsistent pedal feel related to caliper sealing problems
• Corrosion-related caliper performance loss on the front axle

Installation Notes

Verify the vehicle position before ordering, since this part is listed for front left and front right Mercedes-Benz applications depending on model and year. Confirm the bleeder port size, inlet port size, piston material, and bracket requirement against the original caliper. Use the brake fluid specified by the vehicle manufacturer, and follow proper bleeding procedures after installation. For floating caliper mounting pins, use silicone grease as noted in the product FAQs.
