The Wilwood Forged Dynalite Rear Parking Brake Kit (140-10094-D) is a bolt-on rear disc conversion for the Large Chevy C10 5-lug axle housing with a 2.42" axle offset. The manufacturer's configuration pairs forged billet 4-piston black powder-coat calipers with one-piece 12.19" drilled and slotted rotors, BP10 Smart brake pads, and an internal drum parking brake. The manufacturer also describes the forged Dynalite as the base caliper in most of its bolt-on kits. Compared with a stock rear drum setup, this kit gives a C10 rear disc brake with a parking brake that stays inside the hub, and the manufacturer says the design gives balanced braking for vehicles that need a parking brake. The forged calipers use the same 7112-type pad as earlier Dynalite versions, so pad replacement stays simple and the full range of Wilwood pad compounds is available.
The manufacturer states that its rear parking brake kits are not supplied with parking brake cable hardware or adapters. The manufacturer offers a generic parking brake cable kit, part number 330-9371, for this application, sold separately.
The manufacturer lists 15" as the minimum wheel diameter and notes the kit may fit 15-inch wheels. Because clearance varies by wheel design, the manufacturer advises checking the wheel clearance diagram against the specific wheels before purchase.
The manufacturer's listing indicates brake lines are needed. Its installation guidance for this C10 rear kit family also states the kit is not supplied with hydraulic lines or fittings, so plan on purchasing lines or fittings separately.
The manufacturer's assembly instructions for this C10 kit family say installation should be performed only by people experienced with disc brake systems, and recommend photographing the original brake system before disassembly. Before ordering, confirm the axle flange offset matches the 2.42" specified by the kit, since the manufacturer says this dimension is critical for rotor-to-caliper alignment. During installation, the parking brake shoes are adjusted outward with three lug nuts in place until the hat drags slightly. Parking brake cables should be routed as straight as possible, because tight bends reduce pull force at the brake. Users on forums commonly note that the parking brake cable routing and shoe adjustment are the steps that take the most time. Wilwood's documents for some kits in this family list different year ranges, so confirm the exact vehicle year and axle with the manufacturer before ordering.
