Especially if you are going to a star roughly same or higher luminosity, you should have no problem braking with the sail. Also, you probably absolutely need to break with sails since you don't want to carry much fuel to break. Any reasonable amount of fuel required to break will be orders of magnitude more than the payload -- reducing effectiveness of sails by same factor.
