Product details
The red right-hand AeroDM is a front brake caliper used in Wilwood’s documented 2024–2025 Toyota Tacoma conversion. Four smaller bore positions and two larger ones produce a published 5.06-square-inch piston area across the six-piston assembly. A forged body and internal fluid passages form the caliper portion of the full front brake package. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. The company makes disc brake systems and components for motorsport, street-performance and specialized uses, including calipers, brake rotors, master cylinders, valves, fittings and brake lines; each component must match the requirements of the complete brake system.

Fitment & Compatibility
Identify the installed Wilwood package before ordering a replacement, including its rotor configuration. DS1709 gives the complete mounting and wheel-clearance requirements and identifies the correct right/left pair. Check the 7.08-inch lug interface, hydraulic fitting and hose layout rather than relying on model year or a similar-looking Tundra AeroDM body.
