Torque specs (brakes) - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Does anyone know what are the factory torque specs for front/rear brake brackets and for the calipers?

Thanks!

Well, I've used the torque wrench to loose bolts, here is what I measured (front):
guide bolt: 20 lbf
caliper-to-bracket bolt: 105 lbf.

Will do rear later today.

I think 10% should be added.

whoa, that sounds high

try 85!
(just a guess)
If someone knows the factory spec or can tell us what the right number is that would be great

torque to break a fastener and the torque to load on are NOT the same, beware that type of thought, can hurt you more than it can do good

I don't know how trustworthy is this: http://www.torkspec.com/torkspecmm.aspx?KI=494
But it calls for 114 ft-lbs (17 inch type). Very similar brakes.

Front caliper carrier is 59 lb-ft
Rear caliper bracket is 49 lb-ft

Those numbers should be right if I read the schematics from the service manual correctly. You can download the FR-S shop manual here:
