{"product_id":"wilwood-140-15978-bk","title":"Wilwood Rear Electronic Parking Brake Retrofit Kit, Black Calipers for 0.81-Inch Rotors, Controller, Harness and Switch","description":"\u003cp\u003eAdd an electrically operated parking brake to a custom rear brake installation using this black-caliper retrofit kit for 0.81-inch rotors. It supplies a matched pair of motor-driven calipers, the controller, wiring harness and switch hardware. This is a static parking mechanism, not a replacement hydraulic service-brake system. Most installations require custom mounting brackets; the kit does not include rotors, hats or vehicle-specific bracketry. Wilwood Engineering, founded by Bill Wood in 1977, designs and manufactures disc brake systems from its Camarillo, California base. Motorsport, street-performance and specialized applications use its calipers, rotors, master cylinders, valves, fittings and brake lines. Correct component selection depends on the requirements of the entire braking system.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number: 140-15978-BK. Quantity: one kit for the stated axle\/application.\u003c\/li\u003e\n\u003cli\u003eNo replacement wheel hubs are supplied; retain or provide the documented matching hub arrangement.\u003c\/li\u003e\n\u003cli\u003eRotor compatibility: 0.75–0.81-inch thickness, nominal 0.81 inch; rotor diameter 11.00–14.00 inches. Caliper mounting centers: 4.75 inches. Custom brackets must locate the pads correctly on the rotor.\u003c\/li\u003e\n\u003cli\u003eParking caliper: Electronic Parking Brake; 1 piston; steel piston material.

Supplied pad compound: BP-10.\u003c\/li\u003e\n\u003cli\u003eIncludes paired electronic parking calipers, controller, wiring harness, switch and supplied control hardware. Custom caliper mounting brackets, rotors, hubs and hydraulic service brakes are not included.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eUniversal retrofit for a custom rear parking-brake installation using 0.81-inch-thick rotors; no vehicle-specific bolt-on fitment is claimed. Confirm caliper width, mounting-center spacing, rotor diameter\/contact position and clearance for the motors, wheels and suspension. Custom brackets are normally required and are not included. Retain a properly configured hydraulic service-brake system. The EPB is intended for static parking hold, not emergency stopping, and needs the documented electrical supply, fused wiring and controller installation.\u003c\/p\u003e\u003cp\u003eUse PMB Performance’s 20+ years of parts and fitment experience when checking a modified brake layout. The installed mounting hardware and measured wheel space are more useful than model and year alone.\u003c\/p\u003e\u003cp\u003eManufacturer documentation: \u003ca href=\"https:\/\/www.wilwood.com\/PDF\/DataSheets\/ds1353.pdf\"\u003eInstallation instructions\u003c\/a\u003e; \u003ca href=\"https:\/\/www.wilwood.com\/Images\/BrakeKits\/Axle-Offset-Worksheet-Wilwood.pdf\"\u003eTechnical bulletin\u003c\/a\u003e.\u003c\/p\u003e\u003ch3\u003eManufacturer Warning\u003c\/h3\u003e\u003cp\u003eApplicable to brake pads only: Wilwood warns of exposure to arsenic, cadmium, hexavalent chromium compounds, lead, nickel, cobalt and antimony trioxide, chemicals known to California to cause cancer or reproductive harm.
