Wilwood 140-15020 Forged Dynalite Pro Series Front Disc Brake Kit with FDL-M Caliper

The Wilwood 140-15020 is a Forged Dynalite Pro Series Front Disc Brake Conversion Kit featuring the FDL-M caliper and a forged aluminum hub assembly, engineered as a direct bolt-on upgrade for OEM drum brake spindles.

At the heart of this kit is the FDL-M caliper — a purpose-built modification of Wilwood's proven Forged Dynalite design. Its compact four-piston architecture delivers maximum wheel clearance, making it the ideal choice for builds running popular 14" to 15" wheels. The large 10.75" x 0.81" rotor provides a substantial upgrade in stopping power and thermal capacity over the original drum brake setup.

Key Features:

• FDL-M four-piston Forged Dynalite caliper — maximum wheel clearance in its class
• Large 10.75" x 0.81" rotor for enhanced stopping power and heat dissipation
• Forged aluminum hub assembly for reduced unsprung weight
• Designed for OEM drum brake spindles — no spindle modifications required
• Compatible with both manual and power-boosted master cylinders
• Fits inside popular 14" to 15" wheels without clearance issues
• Includes hubs, caliper, brake pads, caliper bracket, mounting hardware, and installation instructions

This kit delivers a complete, bolt-on disc brake conversion with no cutting, welding, or fabrication required. Whether running a stock master cylinder or a power brake booster, the 140-15020 integrates seamlessly into the existing brake system for a clean, high-performance street upgrade.
