Wilwood 120-8476 DH4 Dual Hydraulic Disc Brake Caliper with Parking Brake

The Wilwood DH4 Dual Hydraulic Brake Caliper (120-8476) is an advanced braking solution that combines a primary braking circuit with an integrated secondary hydraulic parking brake system. This innovative design provides both performance braking and secure parking brake functionality in a single compact caliper assembly.

Key Features:

• Step bore piston design with dual hydraulic circuits for primary braking and parking brake functions
• Primary piston bore: 1.50 inches diameter for powerful braking force
• Secondary piston bore: 0.94 inches diameter for isolated parking brake actuation
• Dual 10mm x 1.00 fluid inlet ports for independent circuit operation
• Fully isolated secondary hydraulic circuit prevents cross-contamination between systems
• Precision-machined aluminum construction for lightweight durability
• Ideal for racing applications requiring both performance braking and a reliable parking brake

The DH4's unique dual-circuit architecture allows the parking brake to operate independently from the primary braking system, ensuring reliable parking brake performance without compromising primary brake function. This caliper is designed for custom brake system installations where space constraints and weight savings are critical.
