[V6-12v] C4 caliper bolt size

[Poncho]

Kent, I'm pretty sure they are 8MM.

I had the same problem on my 94 90S.  It turned out to
be rust on the bolt heads.  You need to lightly tap
the 8 mm allen head into the bolt with a hammer.  This
loosens up the rust.

I also had the same fears: some of the bolts, like the
axle flange, are not allen or torx, but rather 10
points I believe.  Don't worry, the carrier mounting
bolts are hex.

Be sure to get  pin boot kits. Comes with the right
grease and pin boot seals.  These G60 Girlings tend to
freeze up the lower carrier pins all the time.
Shortens you brake life significantly and greatly
limits stopping power.  Good luck.
