Wilwood 140-12100-R D154 Front Brake Caliper Kit Red

The Wilwood D154 Front Caliper Kit (140-12100-R) is a high-performance direct bolt-on replacement for OE cast iron "Metric" calipers used on GM mid-size cars and small trucks from 1978 through 2002. This lightweight, extreme-duty upgrade features forged billet aluminum bodies, stainless steel pistons, and competition-grade high-temperature seals that eliminate the rust, bore pitting, and seal failures common in factory calipers.

Key Features:

• Single 2.50" piston design provides 4.90 square inches of piston area per caliper
• Forged billet aluminum construction for significant weight savings over OE cast iron
• Stainless steel pistons resist corrosion and maintain precise tolerances
• Competition-style high-temperature seals for reliable performance on street and track
• Direct bolt-on installation in stock location over factory rotors
• Uses original OE D154 brake pad style for easy maintenance
• Compatible with OE M10-1.5 banjo bolt brake line mounting
• Includes hardened slide pins and BP-10 high-friction brake pads
• Maintains original front-to-rear brake bias with factory master cylinder
• Fits most wheels that clear OE calipers
• Attractive red powder-coated finish

This kit delivers low-maintenance, high-temperature reliability for demanding street and performance applications. The precision-machined aluminum construction provides exceptional strength while dramatically reducing unsprung weight for improved handling and braking response. Matching rear calipers and custom stainless steel brake lines are available separately for complete brake system upgrades.
