Wilwood's D154 Front Caliper Kit is a direct bolt-on 1 or 2 piston, lightweight, high-strength, extreme duty alternative to the OE cast iron "Metric" calipers that were used on a wide range of factory disc brake equipped mid size GM cars and small trucks beginning in 1978. Use of this caliper can still be found on some GM models as late as the year 2002. Forged billet aluminum bodies, stainless steel pistons, and competition style high-temperature seals put an end to the rust, bore pitting, and seal failures that plague the OE caliper design. D154 calipers provide low-maintenance performance and a huge weight savings with high temperature reliability for the street and track. D154 calipers mount in the stock location over stock rotors; use the original style OE D154 brake pads and an OE M10-1.5 banjo bolt brake line mounting. D154 Calipers can be used with most wheels that clear the OE calipers. The front calipers with 2.50” piston provide 4.90 square inches of piston area per caliper, in order to maintain the original front to rear brake bias and use of the OE master cylinder. The D154 is also available in a two piston version with 1.62 pistons, offering 4.12 square inches of area. Kits contain Wilwood’s hardened slide pins and BP-10 high friction pads. Matching rear calipers are also available for custom installations. Custom stainless steel brake lines are also available.
Wilwood Engineering designs and manufactures high-performance disc brake systems. Since the company’s inception in 1977 by Bill Wood, we have developed a substantial matrix of brake components and engineering techniques that allow us to quickly and reliably create brake systems for almost any application. Our core ability is the rapid development of custom engineered brake systems using a combination of off-the-shelf and custom components. In addition to designing and manufacturing brakes for all types of competitive motor sports, Wilwood also manufactures brake systems and components for agricultural equipment, industrial applications, utility vehicles, snowmobiles, quads, motorcycles and military vehicles.
With headquarters in Camarillo, California, Wilwood employs approximately 250 people. We have on-shelf stock of more than 300 different brake calipers, 200 rotor designs, 100 master cylinder designs and a wide assortment of brackets, fittings, valves and brake lines. Our off-shelf brake calipers range in size from tiny calipers used on go-carts and light duty industrial equipment, to heavy duty original equipment brakes for the U.S. military Humvee.
Wilwood's engineering department uses the latest computer-aided design and manufacturing techniques in conjunction with finite element analysis, dynamic test and cycle test equipment, to find high-performance and reliability solutions for the most difficult braking tasks. Our extensive inventory of proprietary on-the-shelf components allow us to provide cost-effective solutions for unique brake applications.
Wilwood is ISO 9000 compliant and has extensive experience maintaining quality levels of 100ppm or less for original equipment manufacturers.
