1964-72 GM A-Body Forged Dynalite Front Disc Brake Kit (12.19" Rotors, 4-Piston) by Wilwood®
4-piston calipers and 12.19-inch rotors; includes hubs, bearings and pads
Upgrade the front brakes on your 1964-72 GM A-Body with this Wilwood® Forged Dynalite kit. The package includes two forged 4-piston aluminum calipers, two 12.19-inch vented iron rotors, separate aluminum hubs and rotor adapters, BP-10 pads, inner and outer wheel bearings, grease seals, dust caps, caliper brackets, shims and mounting hardware. Choose black powder-coated, red powder-coated or polished calipers with plain-face or drilled-and-slotted rotors. Use the matching original drum- or disc-brake spindles; early drum-spindle applications require drilling and tapping as specified in the instructions. The hubs include 1/2-20 wheel studs. Wilwood lists a 0.19-inch outward wheel-offset change per side. Some wheels require a separate hub spacer or shield; see the wheel-contact requirements below. Flex hoses are sold separately; Wilwood lists 220-7056 for this kit. Confirm hose length and chassis fittings. A master cylinder and booster are not included. New spindles are not included. Check Wilwood’s wheel-clearance template; some 15-inch wheels may fit, but diameter alone does not establish clearance.
