Could be something simple and common like dirty throttle body just needing cleaned . This from another forum explains ,
The main reason for zafiras cutting out when braking is due to dirt in the throttle body remove the pipe from the thottle body to air cleaner hold the throttle butterfly open and clean with carb cleaner also when refitting the pipe make sure the pipe from the fuel tank vent is fitted correctly to the back of the throttle body.
