The Wilwood Narrow Superlite 4R rear parking-brake kit for 1958–1964 Olds and Pontiac rear ends combines FNSL4R four-piston calipers with 12.88-inch rotors to deliver a big-brake solution that retains a functional parking brake. These kits include two-piece rotors and BP-10 compound pads to balance braking with front upgrades, and the internal shoe system preserves strong static holding power while keeping the installation visually clean and customizable with optional finishes.
