Wilwood 120-14004-BK Forged Four Piston Brake Caliper - Aero4 Black

The Wilwood 120-14004-BK Aero4 forged four piston brake caliper delivers heavy-duty stopping power for street and track applications. This high-performance caliper incorporates race-proven technology into a versatile body design with widespread adaptability across various braking systems.

Key Features:

• Stress-flow forged construction from premium grade aluminum alloy billet for superior strength and durability
• Four piston design provides balanced clamping force and consistent pad wear
• Radial mounting configuration for secure installation and optimal load distribution
• Compatible with rotor diameters ranging from 12.88 inches to 15.00 inches
• Multiple piston volume options available to suit different braking requirements
• Black anodized finish for corrosion resistance and a professional appearance

Advanced Manufacturing Process:

The Aero4 caliper body utilizes stress-flow forging technology that realigns the aluminum's internal grain structure to flow within the contour of the caliper body. This process eliminates internal stresses and grain interruptions that occur with traditional straight block billet machining, resulting in superior clamping efficiency, ultimate strength against fatigue, and exceptional resistance to distortion under heavy braking loads.

Ideal for heavy-weight vehicle applications requiring reliable, high-performance braking, the Wilwood Aero4 caliper is engineered to deliver consistent stopping power under the most demanding conditions.
