Product details
Yellow powder coat identifies this right-hand Wilwood AERO6 finish. The caliper has six stainless pistons in 1.62/1.12/1.12-inch bores, internal fluid passages and a forged body for a nominally 1.25-inch-wide rotor. Bill Wood established Wilwood Engineering in 1977. Based in Camarillo, California, the company designs and manufactures disc brake systems, from calipers and brake rotors to master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized use.
Technical Details
- Manufacturer part number: 120-13289-Y. Component: Aero6 Radial Mount caliper.
- Supply: one brake caliper, not a complete axle brake kit. Match the mating rotor, pads, bracket and connection hardware to the installation.
- Piston dust boots: not fitted.
- Nominal rotor width 1.25 inch; compatible outside diameter from 12.19 through 15.00 inches. Specified rotor-width limits: 1.10–1.28 inch.
- Bracket interface: 7.09-inch radial centers with 0.45-inch holes. Specified mount height: 2.09 inches; orientation: right hand.
- Bore configuration 1.62/1.12/1.12 inches across 6 pistons; piston material: stainless steel. Hydraulic effective area: 4.04 square inches.
- Construction and surface: forged aluminum housing finished in Yellow powder coat.
- Pad fit is type 6617. Match the pad dimensions and compound to the rotor and intended braking conditions.
- Caliper weight: approximately 6.9 lb.
- Hydraulic inlet thread: 1/8-27 NPT. Use a fitting with the correct thread and sealing seat.
Fitment & Compatibility
The color does not change its mounting or hydraulic specification. Compare the 2.09-inch mount height, 7.09-inch radial centers and 1.10–1.28-inch rotor-width range before selecting the brake bracket and wheel.
With 20+ years of experience, PMB Performance can help compare the actual brake hardware. Supply the caliper number, rotor dimensions and mounting measurements when asking about compatibility.
