i have searched somehow i got the from caliper torque as 85 but not sure if the rear is the same.... i started and it felt like it might be too much so i want to make sure the caliper torque for the 2 bolts on the rear is 85ft lbs

thanks a[ppreciate it

 

you dont need no exact torque spec on that...ive done plenty of caliper swaps on 240's and used the impact gun and never had a problem

 

For the IX:
Front brake assembly mounting bolt 108 ± 10 N⋅m (80 ± 7 ft-lb)
Rear brake assembly mounting bolt 54 ± 5 N⋅m (40 ± 4 ft-lb)

 

haha i did mine at the tq at the fronts oh well , now i know theyre not going anywhere

 

You do realize the calipers are aluminum, you can strip a hole more easily on these than some other calipers... Also, over torquing can lead to over stressing components and possibly cracking something like a bolt, there is a reason for torque specs.

 

ya over tightening and impact gun is ignorant on something aluminum and definatly on a saftey item like brakes. i'm a cat mechanic and i know from experience theres certain things/ most things you do by torque of your arm and hand but things like this need a torque spec thanks for the specs

 

I did the same and destroyed my rear caliper... gotta have it rethreaded/sleeved
stupid mistake, learn from my misfortune.

 

Proper Torque Spec on any Bolt is a must. Sure they will hold after you blast them in with an Impact but it weakens the Bolt actually causing a possible unsafe condition where the Bolt is allowed to stretch, fatigue and break.

You should do some research on the effects of over Torquing Bolts.
