Product details
Six staggered bores and a 7.48-inch lug pattern identify this black left-hand AeroDM front caliper. Wilwood lists it as a component of the documented Toyota Tundra conversion package. It is a forged hydraulic caliper with internal crossovers, intended to be matched to the package’s dedicated rotor and mounting arrangement. Based in Camarillo, California, Wilwood Engineering was founded by Bill Wood in 1977. The manufacturer produces disc brake systems and components for motorsport, street-performance and specialized applications, with a range covering calipers, brake rotors, master cylinders, valves, fittings and brake lines. Individual components are chosen to suit the complete brake system.

Fitment & Compatibility
Compare the existing or proposed kit with DS1695 before selecting the left side. The caliper’s nominal 1.25-inch rotor opening is a thickness specification and does not identify the kit’s rotor diameter. Use the installation drawing for centering, wheel clearance and fitting selection, and retain a master-cylinder setup suited to the complete six-piston system. 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.
