Do you mean the bolts that hold the calipers to the forks or the bolts that split the caliper?

I would think they vary - they do between my two bikes and they are the same manufacturer. I'm assuming you mean the caliper to fork bolts - I have one bike which is 22nm and the other is 33nm to give you an idea. I never mess with brakes so its worth knowing the correct torque but if you coat the bolts in copperslip or similar its worth noting that will affect your torque values.
