140-12100-R D154 Front Caliper Kit — The D154 Front Caliper Kit from Wilwood is a direct bolt-on 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.
This caliper can still be found on some GM models as late as the year 2002.
High-strength forged billet aluminum bodies, stainless steel pistons, and competition style high-temperature seals eliminate the rust, bore pitting, and seal failures that plague the OE caliper design.
D154 calipers offer low-maintenance performance and significant weight savings with high temperature reliability for both 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.
The 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, maintaining the original front to rear brake bias and using 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.
