The Monster Caliper from Scarebird is custom made using a larger 2-3/4" diameter piston to better match the factory hydraulics in some vehicles. The architecture is the 1990 Cadillac Fleetwood caliper, (Will not fit Mopar "A" bodies). We recommend them on 1964-72 GM "A" kits, 1959-64 Impala kits, 1967-69 GM "F" kits, 1957-72 full and intermediate size Mopar's. Fords do not need them as their hydraulics are a good match for the stock Fleetwood unit.
These Monster Calipers have dual bleed screws on top and bottom so are able to be used on either side of your car, plus the brake hose can be clocked for best routing.
They are sold by the pair and come with brake pads, attaching bolts, banjo bolts and copper washers.
