Product Description

The Wilwood 140-7675 Forged Dynalite Big Brake Front Brake Kit is a performance-oriented front braking system engineered for a broad range of classic GM A-Body, F-Body, and X-Body vehicles. The system combines forged four-piston Dynalite calipers with 12.19-inch Ultralite HP 32 vented iron rotors to provide substantially greater braking capacity than many original classic-car brake configurations.

The kit uses aluminum vented-rotor-offset hubs with a +0.19-inch hub offset and supports compatible factory drum, factory disc, and drop-spindle configurations. The standard configuration uses black powder-coated calipers, plain-face rotors, and BP-10 performance brake pads. Wilwood also offers drilled-and-slotted, polished, and red-caliper configurations under related 140-7675 part-number suffixes.

This kit is intended for compatible traditional GM applications including Camaro, Nova, Chevelle, Chevy II, El Camino, Monte Carlo, Firebird, Cutlass, GTO, LeMans, Skylark, and related vehicles. Spindle configuration, wheel clearance, and brake-system compatibility must be verified before installation. The required 220-7056 brake line kit is sold separately.
