Drum to Disc, Manual Brakes, Dual Reservoir Master Cylinder(O.E. Design) Includes everything needed to convert a stock car with drum brakes to 4 piston disc brakes. All kits include calipers which have stainless steel pistons and coated with special stainless steel type paint, stainless steel caliper crossover brake lines, rotors, splash shields, bearings, pads, master cylinder, hoses, and all mounting hardware. For factory equipped 8 cylinder cars spindle replacement is not necessary. Some early cars with 14? stock steel rims may require later 14? steel or optional styled steel rims. Power brake note: When using power brakes the pedal assembly is specific to power or non-power brake cars. Pedal assembly change is required anytime an original power booster is added or subtracted. Our power brake conversions on page 5 do not require pedal change.
