Rear hand brake Caliper torx screw

[AM-DB9]

This is not listed on any shop manual or parts breakout from AM tech.

Is anyone in the know of the spec for these two torx screw/bolts?
I'm hoping to find out before experimenting with pulling one.
Thanks...

Fwiw I bought the ti bolts and caps from pro-bolt.

QUESTION - Why do you want to remove or loosen those torx screws?

Is it to clean up the rust?

[AM-DB9]

yes, I did a rust treatment already but I'm not satisfied with that, so I'm leaning towards replacing them with titanium bolts.
If these were on the back side I wouldn't care, but they are pretty obvious if you glance down at the rear wheels.

OK I understand.

If you cannot find an actual Aston Martin torque spec, you can always use a standard torque chart for metric bolts which should put the bolts in the correct range of tightness. However, if you are changing to a titanium material vs. the factory bolt, then even the factory torque might not be accurate for titanium.
