Dynapro Radial Mount Dust-Sealed Brake Caliper
Dynapro Radial Mount Dust-Sealed (DPR-DS) four piston calipers are an example of Wilwood’s continuing refinement and upgrade processes. They combine pure race technology with a new generation of Wilwood’s performance enhancements. The Dynapro-DS combines radial mount versatility 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.
At an overall weight of just 3.58 pounds, the Dynapro series of calipers have become the popular choice for a wide range of competition, rally, and off-road sport driving applications. The strength of the Dynapro lies in the combination of process and design. The stress-flow forging process re-aligns the internal grain structure of the metal to flow within the contour of the caliper body. This produces a piece with superior strength over machined from billet 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 have proven the effectiveness of this innovative design. In short, a firm pedal with exceptional stopping power. The Dynapro is available in three configurations. Standard brake calipers for rotors 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-radius version is available for rotors up to 13.00”. Race only models use Thermlock insulated pistons for added protection against heat transfer from the pads. All Dynapro calipers can also be upgraded with Thermlock pistons for maximum thermal protection in sustained high temperature applications.Rotor Dimensions
