{"product_id":"wilwood-140-7144-r","title":"Wilwood Mopar\/Dana Red Caliper Rear Parking Brakes — Snap-Ring Bearings, Plain 12.19-inch Rotors","description":"\u003cp\u003eThis red\/plain-disc assembly is for the specified non-adjustable-bearing rear axle. The Forged Dynalite rear disc and parking-brake kit is supplied with red powder-coated 4-piston calipers and 12.19-inch plain-face rotors for Mopar 8-3\/4 \/ Dana 60, snap-ring bearings. Since Bill Wood founded the company in 1977, Camarillo, California-based Wilwood Engineering has designed and manufactured disc brake systems for motorsport, street-performance and specialized applications. Its components include calipers, rotors, master cylinders, valves, fittings and brake lines; all must be matched to the intended brake system.\u003c\/p\u003e\u003ch3\u003ePackage and installation requirements\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eThe one-piece iron drum\/rotors incorporate the parking-brake drums; the internal shoes provide a mechanical parking brake independently of the four-piston service calipers.\u003c\/li\u003e\n\u003cli\u003eParking-brake cables and hydraulic brake lines are separate.

The bearing requirement is essential; a differential name is not a substitute for checking axle retention. Use DS424 to compare the end, bearing and bracket stack before ordering. No vehicle-model fitment is implied for every axle carrying these differential names. Unlike a rear-disc package without a parking mechanism, this kit incorporates drum sections and internal mechanical shoes for that function. A cable installation must still be planned and checked for full release as well as holding operation. Hydraulic hose routing, wheel clearance and compatibility with the vehicle’s master cylinder remain part of the complete brake conversion.\u003c\/p\u003e\u003cp\u003eMeasure clearance at both the caliper and rotor using the instruction-sheet drawing.
