    Wilwood 140-12099-R Details

    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.
