Wilwood 120-14700 Dynapro DS Universal 4 Piston Radial Brake Caliper

Dynapro Radial Mount Dust-Boot Brake Caliper

Dynapro Radial Mount Dust-Boot (DPR-DS) four piston brake calipers are an example of Wilwood’s continuous improvement and upgrade processes. They combine pure race technology with a new generation of Wilwood performance enhancements. The Dynapro-DS combines the versatility of radial mounting with a sleek body profile, superior strength, and extreme durability in adverse conditions. The addition of dust scraper seals allows this caliper to be used in locations that require an environmental sealing method.

Weighing in at a mere 3.58 pounds, the Dynapro caliper series has become a preferred choice for a broad range of Sports Driving, Rally, and Off-Road applications. Dynapro strength lies in the combination of process and design. The real strength flow forging process re-aligns the internal grain structure of the metal to flow within the contour of the caliper body. This produces a part with superior strength over machined or cast parts. The body design, generated through Finite Element Analysis (FEA), features a radial transition between the piston bores and the caliper bridges. This eliminates machined steps and shoulders in this critical strength area and substantially increases resistance to deflection and body separation under high loads. Structural deflection and volume displacement testing has proven the effectiveness of this innovative design. The bottom line result is a firm pedal with exceptional stopping power. The Dynapro is available in three configurations. Standard brake calipers for discs up to 12.19” feature dust sealed stainless steel pistons for maximum protection against track or road grime in medium to high temperature applications. A long-ear version is available for discs up to 13.00”. Race models use Thermlock insulated pistons for added protection against heat transfer from the pads. All Dynapro calipers can also be fitted with Thermlock pistons for maximum heat protection in sustained high temperature applications. Dust Boot Yes
