A twin piston caliper with an electric parking brake and method of operating such a twin piston caliper with an electric parking brake. The twin piston caliper housing comprises two separate inner brake pads for each of the two pistons; one outer brake pad at the outer housing finger area; an electric parking brake mechanism configured to be incorporated in between the two pistons so that it is not embedded in the hydraulic piston and not the hydraulic brake fluid; and wherein the electric parking brake mechanism uses its own electric parking brake friction brake pad to clamp against the brake rotor. The method of operating the twin piston caliper with the electric parking brake comprising the following steps: using hydraulic pressure, preferably high pressure overlay, to clamp up inner brake pads and the outer brake pad against a brake rotor; applying the electric parking brake mechanism to clamp an electric parking brake friction brake pad against the brake rotor; releasing the hydraulic pressure to unclamp the two inner brake pads whereby the electric parking brake mechanism maintains the clamp between the outer brake pad and the electric parking brake friction brake pad.
