Disc Brake Set, Frt & Rr, Rt Stuff, 1969-72 A-Body, 11" Rtrs/Wilwood Calipers

1969-72 GM A-Body Rear Disc Brake Kit (With Matching Front 11" Rotors & Wilwood Calipers) by The Right Stuff®

11-inch rotors and Wilwood two-piston calipers; no parking-brake provision

This The Right Stuff® Performance Series kit converts the rear drums and replaces the existing front disc rotors and calipers on compatible 1969–72 GM A-Body vehicles. It is for cars already equipped with front disc brakes. It supplies four 11-inch drilled-and-slotted rotors and four Wilwood two-piston calipers with pads. Choose black or red calipers. The rear installation parts include brackets, dust shields, braided stainless flex hoses, spacers and mounting hardware. There is no parking-brake mechanism or cable set. The axle flange must match the vendor template: 3-1/8-inch upper bolt spacing, a 2-3/4-inch rotor center and a 6-3/16-inch rotor-hat opening. Larger flanges require machining. Rear wheels move outward 1/8 inch per side; longer studs may be needed. Rear hard lines require shortening or replacement, and hose tabs require welding. A booster, master cylinder and full hard-line set are not included. Check clearance with 15-inch or larger wheels.
