Wilwood D154 2-Piston Rear Caliper Kit - Black - 1.12in Piston for 1.04in Rotor - 140-12101-BK

Upgrade your braking system with the Wilwood D154 Rear Caliper Kit (MPN: 140-12101-BK), a high-performance direct bolt-on 2-piston replacement for original single-piston "Metric" calipers. Engineered for both street and track reliability, these forged billet aluminum calipers provide a significant weight reduction over stock cast-iron units while offering superior strength and heat dissipation.

This kit features dual 1.12-inch stainless steel pistons, providing 1.96 square inches of piston area to achieve proper front-to-rear brake bias in custom applications. The use of stainless steel pistons and competition-style high-temperature seals eliminates the common issues of bore pitting, rust, and seal failure found in OE designs. These calipers mount in the factory location over stock rotors and utilize original-style D154 pads and M10-1.5 banjo bolt hardware for a straightforward installation.
