[s-cars] Brake Caliper to Caliper Bracket Bolts

[Manuel Sanchez]

Fellow S-Heads,

Are the Bolts used to secure the Caliper to the Caliper Mounting  
bracket re-usable or are they supposed to be replaced each time?

I can't really find a reference to this question in the Bentley.

I believe these bolts are supposed to be tightened to 92 ft lb /  
125Nm of torque, correct?

This is for a 993TT BBK, if it makes a difference (probably does).  
I'm not sure of the grade of bolts in a stock set-up, but my  
replacement set coming from 034 is Grade 12.9. Anyone know the stock  
bolt grade?

TIA

Manny
