Wilwood 14.50-Inch Rear Disc Brake Conversion with Red AERO4 Calipers for Specified Toyota Trucks and Lexus LX 570

Red four-piston calipers pair with integral-hat rotors on listed Toyota/Lexus rear axles. Check year limits, parking hardware and machining needs. Bill Wood established Wilwood Engineering in 1977. Based in Camarillo, California, the company designs and builds disc brake systems for motorsport, street-performance and specialized uses, including calipers, rotors, master cylinders, valves, fittings and brake lines. Each part must match the requirements of the whole braking arrangement.

Fitment & Compatibility

Rear application years differ from the matching front family: Tundra is listed for 2007–2015, Land Cruiser J200/Lexus LX 570 for 2008–2011 and 2013–2015, and Sequoia for 2008 only. Do not extend the front Sequoia range to this rear kit or infer the missing 2012 applications. The correct rear rotor diameter is 14.50 inches, with 1.10-inch thickness and an integral iron parking hat. Retain the original parking mechanism. Four-piston dust-sealed AERO4 calipers use BP-20 pads; rear hoses 220-15889 are included. DS-1357 requires cutting the backing plate/dust shield and original upright caliper-mount tabs; qualified machining is necessary. Confirm this work and the wheel template before selecting the kit.

Listed models: Tundra; LX570; Land Cruiser; Sequoia. See the supplied table below for each year, submodel and equipment condition.
