Wilwood 140-16799 D11 Four-Piston Front Brake Caliper Kit for 1965-1967 Mustang

Wilwood's 140-16799 D11 four-piston front brake caliper kit is a direct bolt-on replacement for the original Kelsey-Hayes calipers found on 1965–1967 Ford Mustang, Fairlane, Ranchero, Falcon, Comet, and Mercury Cougar. Engineered to eliminate the chronic rust, bore pitting, fluid leaks, and seal failures that are common failures of the OE caliper design, this kit is a straightforward upgrade that installs in the stock location using the factory brackets and rotors.

Key Features:

• Forged billet aluminum caliper bodies — lightweight and corrosion-resistant construction
• Four-piston D11 design — provides even clamping force across the pad surface for improved braking performance
• Stainless steel pistons — resist corrosion and pitting for long-term reliability
• Internal fluid crossover — cleaner installation with no external crossover tube
• High-temperature seals — engineered to outlast OE rubber seals under repeated heat cycling
• DOT-compliant stainless braided brake lines — included for a complete, ready-to-install kit
• Promatrix performance compound brake pads — included; compatible with factory-style pad replacements
• Direct OE fit — mounts in stock location with original brackets and rotors; no modifications required

The Wilwood 140-16799 kit is an ideal solution for classic Ford enthusiasts looking to restore or upgrade front braking performance with modern materials and engineering. Includes D11 calipers, stainless braided brake lines, and Promatrix brake pads.
