Description

Wilwood's forged DynaPro Big Brake front brake kit (140-14316) is configured for dedicated road racing vehicles such as the Mazda MX-5 Miata and Fiat 124 Spider. It requires 15 in. wheels designed with additional inside clearance to accommodate the larger-than-stock brake package. The 4-piston DP/ST calipers used in this kit feature a forged aluminum body with a Type III Mil-Spec hard anodized, medium gray color finish. Hard anodizing provides superior wear resistance in the piston bores, and high resistance to abrasion and corrosion throughout. Thermlock pistons are used to reduce heat transfer from the pads to increase fade resistance, and to extend service life by decreasing temperatures in the caliper body, fluid, and seals. Internal damper springs and controlled retraction, high-temperature piston seals assure consistent pedal height from start to finish.

Caliper piston volumes are sized for compatibility with OE power brake boosters and master cylinders—and are easily configured with manual brake conversions and balance bar pedals using appropriately sized master cylinders. Spec37 alloy, GT competition series 11.00 in. diameter 72 vane rotors are mounted to either the OE hubs or Wilwood racing ProHubs, with weight-saving forged aluminum hats. Unsprung and rotating weight are minimized while providing high cooling efficiency and rugged durability with thermal stability in sustained high-heat competition. Mounting brackets, including all premium-grade fasteners, secure the calipers in the stock location, without modifications. This race-winning system is completed with high-temperature, high-friction, endurance compound race pads selected specifically by application. Stainless steel braided flexlines are included in each kit to complete the installation.
