The P/S Rear Brake Kit New Big Ford Drilled 2.5in from Wilwood represents a serious upgrade for Ford enthusiasts and mechanics seeking to dramatically improve rear braking performance and heat dissipation. This rear brake system is engineered specifically for newer big-displacement Ford applications where OEM brakes fall short under performance driving, towing, or frequent hard stops. Wilwood drilled rotors coupled with a complete kit assembly eliminate the guesswork from brake system selection, offering a bolt-on solution that professional installers and skilled DIYers alike trust for street cars, trucks, and weekend warriors.
The drilled rotor design is the cornerstone of this kit's thermal management strategy, as the holes promote rapid cooling by allowing hot gases and brake dust to escape through the rotor surface rather than building up on friction faces. The 2.5-inch rotor diameter provides optimal mechanical advantage for rear brake proportioning while the power-stop (P/S) designation ensures this kit integrates seamlessly with existing power-assisted brake systems. Wilwood's engineering delivers consistent pedal feel and modulation across a wide temperature range, critical for trucks handling varied loads and drivers who demand predictable brake response whether cruising or decelerating hard from highway speeds.
This rear brake kit is ideal for Big Ford owners upgrading aging factory brake components, those stepping up to performance driving events, or mechanics building custom trucks and muscle cars where OEM rear brakes lack the stopping power and fade resistance required. Installation fits the rear axle assembly with careful attention to brake line routing and proportioning valve adjustment; professional installation ensures proper bleed procedures and pedal balance tuning. The complete kit approach eliminates compatibility guesswork between rotors, calipers, and hardware—a critical advantage when modifying brake systems where mismatched components can compromise safety and performance.
