Wilwood's D154 forged billet aluminum caliper is a direct bolt-on, lightweight, high-strength, extreme duty alternative to the OE cast iron 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 2002. The wide spread and affordable availability of D154 calipers and brake pad compounds also made it a popular choice in a number of restricted class competition categories and drum to disc conversions on all types of hot rods and street machines.

The D154 GM Metric replacement caliper was designed using computer generated 3D modeling and FEA stress analysis technology and have been configured to mount in the stock location with included OE type slide-pins to position over the rotor. This caliper design features a stress-flow forged billet aluminum body that provides a substantial weight savings over the original cast iron caliper, without any of the rust and corrosion issues that are common to cast iron parts. Stress flow forging realigns the internal grain structure of the metal within the contour of the caliper body to create a caliper that is superior in strength to any cast or machined from block billet caliper design. There simply is no better way to build an aluminum caliper with more strength or less weight.

The D154 calipers utilize stainless steel pistons. Stainless pistons are used to resist corrosion and retard heat transfer from the pads into the caliper body. High temperature, square faced bore seals are used to provide controlled piston retraction and reliable performance from the wider sealing face. This combination of components is a proven performer with long service life and a history of reliable performance in any type of driving environment, including extreme sustained high temperature racing applications. The caliper slide pin holes are fitted with dampening rings to minimize noise from vibration. The caliper is also fitted with bleed screws on both ends to facilitate mounting in any left hand or right hand, front leading mount, or rear trailing mount locations.

The caliper inlet port is threaded for use with a M10 x 1.5 banjo bolt or a line adapter using crush washers as a seal. The OE rubber lines can be used from any vehicle equipped with a M10 x 1.5 banjo.
