The Wilwood AERO4‑DS caliper is a dust‑sealed variant of the AERO4 family, specified here with a 1.12 piston and matched to a .81" rotor. It integrates race‑derived design with internal fluid routing and an environmental seal to protect the piston bore from dust and corrosion. This configuration suits applications that require a compact AERO4 caliper with added contamination protection.
