Brake Pads
Set of Brand New Wilwood D-154 Floating Dual Piston Racing Brake Calipers & Pads (Part #140-12101-R).
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.
