What size Torx bit
 

for the brake caliper bolts?

I am getting ready to do a brake job and found that my torx bits only go up to size T50 - too small. Will probably need T55, T60, or T70. I am guessing T60. Does anyone know for sure? Thanks.

Should be T55

I believe that the caliper bolts are a hex head bolt, not a Torx.

Good point. The new bolts I ordered from SunCoast are torx. I need to check the brake caliper on the car (2007 Boxster S) to see if they are torx or hex.

My 2001 base had 10mm hex (allen style). The replacements are now T55

Internal or external Torx ? Hopefully external & if so sometimes a 6 point socket works.

It's internal, T55 not E55
