I will soon be doing a DIY brake pad replacement on a BMW. I watched a DIY youtube video on how to do this job & the presenter on 2 occasions uses Torx bits instead of Triple Square bits. On the first occasion he uses a T30 Torx bit & on the second occasion he uses a T45 Torx bit. On both occasions he mentions that the proper bit to use would be a Triple Square but since he does not have the proper size Triple Square the Torx works just fine. I would really like to use the proper bits if possible but I don't know & can't find the equivalent sizes of bits. Does anyone know what size Triple Square bit would be equivalent to a Torx30 & what size Triple Square would be equivalent to a T45 Torx bit? I know I could buy a whole set of Triple Square bits, but since I would only be using 2 bits & only using them once I would rather just buy the 2 bits I would need. I'm guessing that buying only the 2 bits I need as opposed to a whole set of Triple Squares would save me a few bucks. Thanks
