Wilwood 120-17081 HE1 Hydra-Mechanical Sliding Disc Brake Caliper 1.25in Bore

The Wilwood 120-17081 is a compact, low-profile HE1 Hydra-Mechanical sliding mount disc brake caliper engineered for versatility across recreational, industrial, utility, and specialty vehicle applications. Combining hydraulic braking with a mechanical actuator mechanism derived from Wilwood's Electronic Parking Brake Caliper platform, this unit delivers reliable, dual-mode stopping performance in a space-saving package.

Key Features:

• Sliding mount design — Low-profile, compact form factor for tight installation environments
• 1.25" piston bore size — Delivers consistent hydraulic clamping force
• Compatible rotor diameter range: 11.00" to 14.00"
• Compatible rotor thickness range: 0.16" to 0.39"
• Hydra-Mechanical actuation — Integrates hydraulic service braking with mechanical parking/emergency brake capability
• Utilizes proven gearing and motor components from Wilwood's original Electronic Parking Brake Caliper design
• Suitable for recreational, industrial, utility, and other specialty vehicle platforms

The HE1 Hydra-Mechanical caliper is ideal for builders and OEM integrators who require a single caliper solution that handles both service and parking brake duties without the need for a separate mechanical drum or secondary caliper. Its sliding mount architecture simplifies bracket design and reduces overall system weight.
