{"product_id":"wilwood-140-16170-dr","title":"Wilwood Red Rear AERO4 Brake Conversion with Drilled Rotors and EPB, 14-Inch Diameter, New-Style Big Ford 2.36-Inch Axles","description":"\u003cp\u003eRed AERO4 service calipers clamp drilled 14-inch Spec-37 rings in this axle-specific rear conversion. Matching red EPB units supply static parking hold through the included control system, with the 2.36-inch offset positioning the brake assembly. Wilwood Engineering, founded by Bill Wood in 1977, designs and manufactures disc brake systems from Camarillo, California. Its motorsport, street-performance and specialized product range spans calipers, brake rotors, master cylinders, valves, fittings and brake lines. A conversion must be considered as a complete brake system when selecting those parts.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number — 140-16170-DR; supplied as one rear axle brake kit.\u003c\/li\u003e\n\u003cli\u003eCaliper finish and port — Red Powder Coat; hydraulic inlet 1\/8-27 NPT.\u003c\/li\u003e\n\u003cli\u003eRotor dimensions — 14.00 in; 355.6 mm outside diameter; 1.10 in; 27.94 mm thick.\u003c\/li\u003e\n\u003cli\u003eRotor material and surface — Spec-37 Iron; vented; SRP Drilled \u0026amp; Slotted; surface finish Black Electro Coat.\u003c\/li\u003e\n\u003cli\u003eMinimum nominal wheel diameter — 18 in; 457.2 mm; full spoke\/barrel clearance must be checked using the installation drawing.\u003c\/li\u003e\n\u003cli\u003eMechanical contents — Separate wheel hubs are not included; mounting hardware supplied; spindles not included.\u003c\/li\u003e\n\u003cli\u003eHydraulic service calipers — AERO4; 4 pistons per caliper; Forged Aluminium body; radial mounting; Stainless pistons.\u003c\/li\u003e\n\u003cli\u003eCataloged rotor\/hat mounting-hole pattern — 5 x 4.5 in; 5 x 114.3 mm; 5 x 4.75 in; 5 x 120.65 mm; 5 x 5 in; 5 x 127 mm bolt circle; cataloged stud-hole clearances 0.520 in; 13.21 mm.

Verify the bearing arrangement, axle register and wheel-bolt pattern independently, including any changes made during a previous axle conversion. Use the full 18-inch minimum wheel envelope for both caliper positions.\u003c\/p\u003e\u003cp\u003eAny vehicle application in the fitment table below depends on the installed axle interface. Compare flange and bearing geometry, axle offset, center register and wheel hardware with the specified assembly. For a 1990 Lincoln Town Car, identify the actual axle and confirm the specified interface; do not select this conversion from model and year alone.\u003c\/p\u003e\u003cp\u003eThe supplied EPB switch and pigtail connect through a universal harness to the controller and separate parking-caliper motors. Vehicle-specific power, ground and ignition\/accessory wiring still requires installation under DS1353. This static-hold system is independent of the service brakes and is not intended for emergency stopping.\u003c\/p\u003e\u003cp\u003eFor help checking the installation, contact PMB Performance with the vehicle year and photographs of the existing brakes.
