I plan on tackling disassembly of the Brembo calipers in order to prep them for powder coating. Now the only issue is I知 not sure of the torque specs. On similar Brembos (evo and sti) forums claim 80ft/lbs, 33ft/lbs, and 125ft/lbs. What would the torque be for our bolts that hold the two halves? When it comes to something like this, last thing I want is a leaking caliper or snapped bolts.

not sure if you ever found your answer, but keep in mind that these are probably M8 or M10 e-torx bolts threading into aluminum. I searched around too and I see numbers that vary based on the length & diameter of the bolts, thread depth, as well and if the caliper has o-ring seals or just two flat face mating. take these as reference, not the actual number but should ballpark you.
https://rennlist.com/forums/964-foru...ml#post2334852 https://forums.nicoclub.com/caliper-....html#p6820488 just remember, the 70ft lbs some guys state seems pretty high. No way its going to be over 100. I would scribe a bolt had to the body, a clocking mark. Loosen one and then use a torque wrench to move it back, might take a few tries but see if you can zero in on the setting. Start at 25ftlbs, if the wrench clicks/beeps before you clock back to the right position, then you exceeded, if not, raise it in 5lb increments. Hopefully that makes sense. I didnt see any exact calipers being discussed and since it varies based on several factors, just try and find it slowly. |

I知 getting my brake calipers powder coated and I知 trying to find the same information. I already split my calipers or else that advice would have been a pretty good idea.
Can someone provide an update if they know the factory torque specs? Or Zoomz can you tell us how your brakes are holding up with the 55/30 torques you used? Did you use any thread locker? I知 thinking I probably will. |
