FORGED BILLET D154 GM METRIC
OE MOUNT REPLACEMENT CALIPER
Caliper Highlights:
The D154 GM Metric forged billet 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 the year 2002. The wide
spread and affordable availability of D154 GM Metric
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 have been configured to mount in the stock
location with included OE type slide-pins to position over the
original rotor using standard OE type
brake pads . 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.
There are three piston configurations available; the large 2.50” single piston, and two, two-piston models featuring
1.62/1.62” or 1.12/1.12” pistons. All three 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.
To complete the package, D154 calipers are available as a regular stock item with brake fluid resistant, high-temp
glossy red or black powder coat, or available polished for those wishing to add a different customized look inside the
wheels.
