Just bought a 1996 Aurora and the brake pads and rotors need replaced. I have a T60 Torx I use to remove the calipers on my other GM car but tried it on this and is too big.
What size Torx do I need to get? I was thinking 55 or 50 but wanted to check before I purchase both.
Also, any other special sockets needed? I have the piston compressing tools that I use on my other GM, hope that's the same.

Thank you.
