Wilwood 120-16510-BK D11 4-Piston Disc Brake Caliper Black

The Wilwood D11 4-piston disc brake caliper is a direct bolt-on replacement for original equipment Kelsey-Hayes calipers on 1965-67 Ford Mustang, Fairlane, Ranchero, Falcon, Comet, and Mercury Cougar models. This performance upgrade eliminates common OE caliper problems including rust, fluid leaks, bore pitting, and seal failures.

Key Features:

• Forged billet aluminum body with durable black powder coat finish
• Internal fluid crossover design for cleaner installation
• Stainless steel pistons resist corrosion and maintain consistent performance
• High-temperature seals for reliable operation under demanding conditions
• Uses OE-style D11 brake pads for easy pad replacement
• Mounts in stock location with original brackets and rotors
• Same overall piston volume as original calipers maintains proper brake balance
• Fits inside most production steel wheels and later model alloy wheels
• 1/8"-27 NPT inlet fitting

Installation Notes:

This caliper mounts in the factory location over stock rotors using original mounting brackets. The only modification required is a new brake flexline with a 1/8"-27 NPT end to match the aluminum caliper inlet. No master cylinder changes or brake bias adjustments are necessary, making this an ideal plug-and-play performance upgrade for classic Ford and Mercury applications.
