Looking to fit new brake discs to my 2007 Vantage and understand that the caliper bolts are single use items. Can anyone recommend where I get these from and cost involved.
Also what is the recommended torque setting when refitting.
Thanks in advance.

I got them from HWM, just give them a call or drop them an email. From memory they were 20Nm for brake caliper and 15Nm for handbrake calipers.

Just for clarity, in Parcubs response, he quotes 20Nm plus 66 to 70deg.
I assume you set your wrench to 20Nm and once you get there you tighten (ie turn)the bolts by a further 66 to 70deg.
If correct it begs the question of why don’t they just quote a higher torque setting?
Also is it advisable to use thread lock on the bolts?

The bolts yield under load, ie stretch as you tighten them, I believe this means that torque is a bad indicator of when they are correctly tightened. The handbrake calliper bolts come with some thread lock type stuff on them. As someone who is a bit OCD, I made a large protractor out of cardboard to get the angle right.

I'm just in the process of doing a complete refresh on mine. Really should do a thread on what I have learnt.
