Fab-Tek Wilwood Calipers The Store

Calipers

Wilwood manufactures brake calipers covering a range of applications from world class professional motorsports to the weekend sports driver and recreational vehicle enthusiast. The overall pad size, shape, and available friction material volume are key factors in the caliper selection process.

Wilwood calipers are manufactured from specific and proprietary aluminum alloys. Calipers may be forged from premium grade alloy billets, machined from billet stock or formed using close tolerance casting processes.

Many caliper models are offered with a choice of piston sizes, construction and materials. Combined piston area, not caliper size, is the primary influence on a caliper’s clamping power. The piston volume must match the master cylinder bore size and pedal leverage to realize peak performance. Rotor diameter will also impact the system’s effectiveness. Different piston sizes provide the car builder with options to maximize the overall balance and brake system performance.

Piston material is selected based on the caliper’s intended operating environment. Stainless steel pistons are used most often in calipers intended for high performance or competition applications. Stainless steel is selected for its low heat transfer properties and high resistance to corrosion. For extreme temperature environments, Wilwood’s exclusive multi-piece insulated Thermlock® pistons provide ultimate protection against heat transfer from the brake pads into the caliper body, piston seals, and brake fluid. Aluminum pistons are only used in low to medium temperature applications, usually in conjunction with rubber piston boots that protect the pistons from corrosion and debris.

Wilwood incorporates a variety of innovative and time proven performance enhancements in its caliper designs. They include, radial mounting, differential piston bores, high temperature seals, SRS Squeal Reduction and bridge reinforcement plates, internal heat shields, quick access pad retention, shock dampened fluid tubes, and center bridge bolts. A durable black anodized finish is standard, with some available in red or a polished finish for show car applications. The availability and benefits of features are discussed further in the individual product listings.
