Wilwood 120-17773-RD Forged Billet Dynalite-M Disc Brake Caliper - Red

The Wilwood Forged Billet Dynalite-M disc brake caliper represents a significant enhancement over the venerable Forged Dynalite series. Specifically engineered to maximize outboard clearance, this caliper incorporates the latest innovations in caliper design and stress-flow forging technology to deliver exceptional strength and performance in its class.

Advanced Forging Technology:

The stress-flow forging process re-aligns the metal's grain structure to follow the contour of the caliper body, eliminating the breaks and interruptions that occur when machining a straight billet. This results in a caliper that is substantially stronger and more resistant to deflection under heavy braking loads, while maintaining an incredibly light weight starting at just 2.80 pounds.

FEA-Optimized Design:

The radial transition design, generated through Finite Element Analysis, eliminates traditional steps and shoulders between the piston housing and caliper bridges. This radiused transition area dramatically increases resistance to deflection and caliper separation under load. Structural testing has proven the Forged Dynalite-M outperforms all comparable calipers in its size class, with reduced deflection translating directly to decreased fluid volume displacement, increased clamping efficiency, less pedal travel, and improved stopping power.

Premium Performance Features:

• SRS (Stainless Rotor Saver) bridge plates eliminate bridge wear from pad gouging and extend caliper service life
• Spring-loaded SRS plates eliminate pad rattle and dampen vibration harmonics to reduce brake squeal
• High-temperature seals maintain performance under extreme conditions
• Stainless steel pistons eliminate corrosion and retard heat transfer from brake pads
• Internal fluid passages eliminate external brake lines for cleaner installation
• Four-corner bleed screws enable complete air evacuation and universal mounting position capability
• Bright red anodized finish provides corrosion resistance and distinctive appearance

This caliper delivers race-proven reliability with a taller, firmer brake pedal and superior stopping performance for demanding motorsports and high-performance street applications.
