Wilwood 120-14700 Dynapro Radial Mount Dust Seal Brake Caliper - 4-Piston

The Wilwood DynaPro-DS four-piston radial mount brake caliper combines the versatility of radial mounting with a sleek low-profile design, superior strength, and extreme durability in harsh conditions. This caliper has become a favored choice for sports car, rally, and off-road driving applications where demanding brake performance is essential.

Advanced Stress-Flow Forging Process:

The exceptional strength of the DynaPro caliper results from Wilwood's stress-flow forging process, which re-aligns the internal grain structure of the metal to flow within the contour of the caliper body. This manufacturing method produces a component with superior strength compared to machined billet or cast parts, delivering enhanced durability under extreme loads.

FEA-Optimized Body Design:

The caliper body features a computer-generated (FEA) design with radial transitions 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-load conditions. Structural deflection and volume displacement testing confirm the efficiency of this innovative design, resulting in a firm pedal feel with outstanding stopping power.

Dust Seal Protection:

This DynaPro-DS model features dust-sealed stainless steel pistons that provide maximum protection against track or road debris in intermediate to high-temperature braking applications. The dust seal design extends caliper life in adverse environments while maintaining consistent performance.

Key Features:

• Four-piston radial mount configuration for versatile mounting options
• Stress-flow forged construction for superior strength and durability
• Dust-sealed stainless steel pistons resist contamination
• FEA-optimized body design minimizes deflection under load
