It really depends which model you have and what year it is. Having checked multiple manuals, I would suggest that you at bare minimum have a:
15mm and/or an 18mm wrench for the caliper bracket bolts.
The guide bolts can be either a T40 or T45 Torx bit. It is also possible that you have Allen bolts for the guide, those can be 7mm and/or 9mm
You may also need a either 32mm or 34mm socket for the spindle nut, depending on your model. You may rent those from places like Autozone etc. You will of course also need the tools to remove your wheel. Personally, if you are inclined to perform further repairs by yourself, I'd suggest purchasing quality metric wrench and socket sets, instead of individual pieces. Hope this helps, good luck.
