Wilwood 120-14702 Dynapro Radial Mount Dust Seal Brake Caliper - 4-Piston

The Wilwood Dynapro-DS four-piston dust seal radial mount caliper combines versatile radial mounting with a sleek profile, superior strength, and extreme durability in adverse conditions. This performance caliper has become a favored choice for sports, rally, and off-road driving applications where reliability and stopping power are critical.

Stress-Flow Forged Construction:

The strength of the Dynapro caliper is achieved through advanced stress-flow forging, which re-aligns the internal grain structure of the metal to flow within the contour of the caliper body. This manufacturing process produces a component with superior strength compared to machined billet parts or castings, delivering exceptional durability under extreme loads.

FEA-Optimized Design:

The caliper body features an FEA (Finite Element Analysis) generated design with a radial transition between the piston bores and caliper bridges. This eliminates machined steps and shoulders in critical stress areas, substantially increasing resistance against deflection and body separation under high loads. Structural deflection and volume displacement testing have proven the efficiency of this innovative design, resulting in a firm pedal feel with outstanding stopping power.

Dust Seal Protection:

This model features dust-sealed stainless steel pistons that provide maximum protection against track or road-borne debris in intermediate to high-temperature applications. The dust seals extend caliper life and maintain consistent performance in harsh environments.

Key Features:

• Four-piston radial mount configuration
• Stress-flow forged body for maximum strength
• Dust-sealed stainless steel pistons
• FEA-optimized body design reduces deflection
• Radial transition eliminates stress concentrations
• Anodized finish for corrosion resistance
• Suitable for rotors up to 12.19 inches
• Ideal for sports, rally, and off-road applications

The Dynapro-DS caliper delivers professional-grade braking performance with the durability needed for demanding motorsports and high-performance street applications.
