The Wilwood Forged Dynalite P/S Park Brake Kit (140-13511-DR) is a complete rear disc-and-parking-brake assembly for popular muscle car rear axles. It is built on Wilwood's forged Dynalite platform, and the "P/S" designation means the kit combines a service brake with an integrated internal-shoe parking brake in the rotor hat. Compared with a stock drum setup, a kit like this gives a serious street/strip or show build a bigger, more fade-resistant rear brake and a parking brake that holds on a grade. Its main advantage over cheaper bolt-on rear kits is the forged caliper and one-piece rotor-and-hat design. Confirm the axle type before you buy: the manufacturer's catalog says the Forged Dynalite parking kit fits BOP-type axles with a 2.75" diameter retained bearing and will not fit C-clip axles. Searchers looking for a "BOP 2.75 offset rear parking brake kit," "Wilwood Dynalite P/S park brake," or "drilled red rear disc brake conversion" will find this part number matches.
Installation is a job for an experienced hand. Wilwood's instructions state that its brake kits should be installed only by people experienced with disc brake systems. Plan on a separate Wilwood parking brake cable kit, which the manufacturer lists as sold separately, and keep anti-seize on all aluminum nuts as the manufacturer recommends. Route the cables along the original factory path, keep them clear of exhaust and moving suspension, and confirm holding power after bedding the pads. Expect the parking brake to need cable adjustment after install, so verify fit before final assembly.
The manufacturer states that the Forged Dynalite parking brake kit fits BOP-type axles using a 2.75" diameter retained bearing and will not fit C-clip retained axles. Verify your axle retention style before ordering.
The manufacturer's catalog notes that some variants in the Forged Dynalite parking brake family require a snap-ring style green bearing. Confirm the bearing requirement for this exact part number with the manufacturer before installation.
Per the manufacturer's install guidance, this kit should be fitted only by someone experienced with disc brake systems, and the parking brake cable kit is purchased separately. Use anti-seize on aluminum nuts, route the parking brake cables along the original path away from exhaust and moving suspension components, and check parking brake holding power after the brakes are bedded. Common gotchas include cable clearance and retention, plus parking brake adjustment once the cables are connected. Confirm bearing style and axle retention before you start, because the kit will not fit a C-clip axle.
