Wilwood D154 Front Caliper Kit - Black with 1.62 Inch Pistons for Mid-Size GM Vehicles

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.

The Wilwood D154 Front Caliper Kit offers a high-performance, lightweight brake solution designed for mid-size GM cars and small trucks originally equipped with OE cast iron 'Metric' calipers. Featuring forged billet aluminum bodies, stainless steel pistons, and competition-style high-temperature seals, these calipers resist rust, bore pitting, and seal failures common with factory components. They provide low-maintenance performance and significant weight savings, making them suitable for both street driving and track use. The calipers mount in the stock location over OE rotors and utilize original-style OE D154 brake pads along with an OE M10-1.5 banjo bolt brake line fitting, ensuring compatibility with most wheels that clear the OE calipers. The 1.62-inch piston size maintains the original front-to-rear brake bias by offering 4.12 square inches of piston area per caliper, preserving the vehicle's braking balance when used with the stock master cylinder. Each kit includes Wilwood’s hardened slide pins and high-friction BP-10 brake pads, designed to withstand extreme conditions while providing reliable stopping power. Custom stainless steel brake lines are also available to complete the upgrade. These calipers are an excellent choice for enthusiasts seeking a durable, high-performance upgrade that maintains OEM fitment and enhances braking confidence on both street and track environments.
