Any idea on what size torx bit fits the font calipers on this?...I'd like to meet the idiot that decided to put torx bolts on the front brakes while using hex bolts on the rear (as it should be)..

These things are a nightmare to loosen with this configuration.

Can't find the correct size anywhere..t50 & t55 are the standard tool size. appears to be a 52-54. Where is one available?

Thanks
