Wilwood 140-11857-U D8-6 6-Piston Front Brake Caliper Kit Uncoated

The Wilwood D8-6 Front Brake Caliper Kit (140-11857-U) is a direct bolt-on performance upgrade delivering six-piston stopping power in a lightweight, durable aluminum package. This kit features an uncoated gray/silver natural aluminum finish and is engineered as a precision replacement for worn or corroded OE-style single-piston front brake calipers.

Key Features:

• Six-Piston Fixed Caliper Design: Differential bore six-piston layout matches the overall piston volume of the original OE caliper, preserving factory pedal feel and master cylinder compatibility while delivering superior clamping force
• Forged Billet Aluminum Body: High-strength forged aluminum construction significantly reduces unsprung weight compared to OE cast iron calipers while improving rigidity and heat dissipation
• Stainless Steel Pistons: Corrosion-resistant stainless steel pistons eliminate the bore pitting and rust that commonly plague OE caliper designs
• High-Temperature Seals: Square-cut O-ring seals retained in the caliper bore provide reliable sealing under sustained high-heat conditions
• Stainless Steel Bridge Wear Plates: Integrated wear plates protect the caliper body from pad backing plate contact, extending caliper service life
• Stock Rotor Compatible: Mounts in the OEM location over stock rotors — no rotor upgrade required
• D8 Pad Compatible: Uses widely available standard D8 brake pads for easy future servicing
• DOT-Compliant Stainless Braided Brake Lines: Kit includes DOT-compliant stainless steel braided brake hoses for improved pedal response and brake line longevity
• Uncoated Finish: Natural gray/silver aluminum appearance; no powdercoat or anodize — ideal for custom finishing or a clean, understated look
• Wheel Clearance: Fits snugly inside most 1967 and newer production wheels; some early OE steel wheels or select aftermarket replica wheels may require a 3/16 in. or wider wheel spacer

Kit Includes:

• Pair of D8-6 six-piston front brake calipers (uncoated finish)
• DOT-compliant stainless steel braided brake hoses
• High-friction brake pads

The Wilwood D8-6 caliper kit is sold as a complete front axle set, making it a straightforward solution for restorers and performance enthusiasts looking to modernize their braking system with proven Wilwood engineering and minimal modification to the existing brake setup.
