Wilwood 120-17205 Radial Mount Brake Caliper Anodized - XRS4R 4-Piston

The Wilwood 120-17205 is a XRS4R 4-Piston Radial Mount Brake Caliper finished in a durable anodized coating. Engineered by Wilwood for high-performance street and competition applications, this caliper delivers consistent, fade-resistant stopping power through its multi-piston fixed design and precision-machined aluminum construction.

Key Features:

• 4-Piston Fixed Design: Provides balanced, even clamping force across the brake pad for improved modulation and wear consistency
• Radial Mount Configuration: Simplifies installation and allows precise two-plane alignment over the rotor for optimal pad-to-disc contact
• Anodized Aluminum Body: Lightweight, corrosion-resistant finish protects the caliper in demanding environments while maintaining a high-performance appearance
• High-Temperature Seals: Engineered to withstand the heat generated in aggressive braking scenarios, maintaining seal integrity under repeated hard stops
• Stainless Steel Pistons: Resist corrosion and reduce heat transfer from brake pads to caliper fluid
• Internal Fluid Passages: Eliminate external brake lines across the caliper bridge for a cleaner, more reliable installation
• Multi-Position Bleed Screws: Allow the caliper to be mounted in front, rear, left, or right positions without compromising brake bleeding efficiency

Wilwood's XRS4R caliper series is a trusted choice for performance builders seeking a lightweight, race-proven braking solution. The radial mount design offers straightforward fitment flexibility across a wide range of custom, race, and street performance builds.
