The flexi is the rubber coated thick brake hose which runs from the caliper up to the rigid brake line poking through the wheelarch.
Over time, the flexi hose can corrode / break down internally lead to blockages which, whilst they can be cleared under the very high pressures generated when you press the brake pedal, can stop the fluid running back causing the caliper piston to stick out, or bind. Often leading to the assumption that the caliper is knackered.
Way to check is to get the sticking wheel of the ground and crack the bleed nipple briefly on the caliper. If the wheel moves more freely after this, it's your flexi hose.
