It is a good idea to use the same type master for sure.

replacing the brake fluid is a snap-a-roo because the change of colour is easy to see. You will also get better pressure on the pedal when you fix the leak. How is the paint on your car? Fluid will eat it... If you want to make sure everything is tip top, you may want to cut the ends off the brake lines and put new fittings on. If you don't have a flare tool, I and many others do as well as a proper tube cutter. If you need to use it , pas de problem.
