Product details
The black right-hand AeroDM is a six-piston front caliper used in Wilwood’s documented Toyota Tundra brake package. A forged body and internal fluid routing support the direct spindle-mount layout, with staggered 1.75/1.62/1.62-inch bores. This listing is for the individual caliper, not the rotors, hose kit or full front axle package. Founded in 1977 by Bill Wood, Wilwood Engineering is based in Camarillo, California. Its disc brake systems and components serve motorsport, street-performance and specialized applications. Calipers, brake rotors, master cylinders, valves, fittings and brake lines are among its products, selected according to the complete brake system’s requirements.

Fitment & Compatibility
Wilwood’s DS1695 identifies this caliper pair in the front kit for the documented Tundra application. Match the complete kit reference and its rotor arrangement rather than treating the caliper as a standalone original-brake replacement. Confirm the 7.48-inch lug spacing, spindle mounting, hose routing and wheel clearance with the applicable installation instructions. 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.
