Torque settings for front AP calipers

[Limitless]

Hi all, I'm cleaning and re greasing my 420r front hub bearings but can't find the torque settings for the two bolts as in the pic. Anyone know?

I couldn't find a setting for them anywhere, so I used the old caliper to upright bolt setting of 58Nm (from the 2015c manual page 213).  The problem is normally removing them from the old uprights, the amount of thread lock combined with a odd shape E12 socket means stripping the head is a real possibility.  I have tried three sockets, eventually finding one that can remove the bolts without damage.

Couple of spots of medium strength threadlock ... all it needs.

Thanks ChrisC that's a great help. I too had seen 58Nm on the AP site but that was for the 4 pot caliper.

I would strongly recommend changing the bolts for good quality cap heads, as said above sooner or later the odd Torx bolts will cause a problem. 

There’s a whole other thread on that one with all the info you need.

If you can get the Torx cap heads (female Torx) rather than the male ones originally used

Thanks for the info guys, will get some cap heads. Managed to get them off without any dramas. Bearings all cleaned and re greased, discs are having the insides sprayed (where they rust) hubs sprayed and the uprights painted with smooth silver Hammerite. Looking like new again!

Next job is to clean the calipers with brake cleaner and a tooth brush.
