Product details
This red AeroDM is the right-hand front caliper within the Toyota Tundra package identified in Wilwood’s installation documentation. Six stainless pistons act in a forged aluminum body with a published 6.52-square-inch piston area. The 7.48-inch mounting pattern distinguishes its spindle interface from the smaller-spacing Tacoma version. Bill Wood founded Wilwood Engineering in 1977; the company is based in Camarillo, California. Wilwood designs and manufactures disc brake systems and components, from calipers and brake rotors to master cylinders, valves, fittings and brake lines, for motorsport, street-performance and specialized applications; selection depends on the complete brake system.

Fitment & Compatibility
Order against the installed Wilwood kit or its approved application instructions. The matching kit uses a specific rotor and hydraulic line arrangement; year and model alone do not make this bare caliper interchangeable with the factory assembly. Check side, rotor centerline and wheel-spoke clearance, and verify the full mounting hardware specification. The documented application is Toyota Tundra (2007–2015). The kit-specific rotor dimensions govern the matched assembly; do not treat the nominal caliper opening as approval for unrelated rotors.
For help identifying the correct brake component, provide the caliper markings and installation dimensions. PMB Performance has over 20 years of experience with parts and brake-system details.
