{"product_id":"wilwood-140-7578","title":"Wilwood Chevrolet Special-End Parking-Brake Conversion — Black Calipers, Plain Rear 12.19-inch Rotors","description":"\u003cp\u003eA 3.15-inch fixed bearing distinguishes this Special-end Chevrolet kit from OE C-clip packages. This Forged Dynalite rear disc and parking-brake kit combines black powder-coated 4-piston calipers and 12.19-inch plain-face rotors. Founded in 1977 by Bill Wood and based in Camarillo, California, Wilwood Engineering designs and manufactures disc brake systems for motorsport, street-performance and specialized applications. Its range includes calipers, brake rotors, master cylinders, valves, fittings and brake lines, selected to work together as a complete brake system.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number: 140-7578.\u003c\/li\u003e\n\u003cli\u003eRotor dimensions: 12.19 in; 309.63 mm diameter x 0.81 in; 20.57 mm thick.\u003c\/li\u003e\n\u003cli\u003eRotor construction: Iron; vented; Plain Face friction surface.\u003c\/li\u003e\n\u003cli\u003eCalipers: 4 pistons; forged aluminum; stainless steel pistons.\u003c\/li\u003e\n\u003cli\u003eCaliper attachment: lug mount; 1\/8-27 NPT hydraulic inlet.\u003c\/li\u003e\n\u003cli\u003eCaliper finish: Black Powder Coat.\u003c\/li\u003e\n\u003cli\u003eRotor\/hat wheel-stud clearance patterns: 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.\u003c\/li\u003e\n\u003cli\u003eRotor\/hat stud-hole clearance diameters: 0.52 in; 13.21 mm.

It is distinct from Wilwood’s OE C-clip-end conversion. Verify the fixed-bearing housing-end dimensions in DS445 before interpreting any of the vehicle applications below. A modified Camaro, Chevelle or other listed GM car may have several possible rear ends, regardless of its front spindle setup. In this package the rear rotor also contains the drum for the internal parking shoes, giving the mechanical parking system its own friction surface. Complete the installation plan with cable adaptation, hydraulic lines and a wheel-template check. If the axle bearing or retaining hardware cannot be identified, obtain that information before selecting the kit.\u003c\/p\u003e\u003cp\u003eThe application table below identifies the model-year and factory-equipment combinations.
