Torque for the brake caliper bolts

FRONT:

4) Install the caliper body on support. Tightening torque: Non-turbo model: 26.5 N.m (2.70 kgf-m, 19.5 ft-lb) Turbo model: 37 N.m (3.8 kgf-m, 27.5 ft-lb)

REAR:

3) Install the caliper body on support. Tightening torque: 37 N-m (3.8 kgf-m, 27.5 ft-lb)

thx for the answer but I just wonder why there such big difference?

I'm not sure... I know the WRX rotors are slightly larger, but I'm pretty sure that in the 02, the calipers were the same. I actually torque mine to about 30 ft-lb anyway... I can't say I'd recommend that though, broken bolts suck.

Being bigger brakes, the components have to be sturdier. This is how i understand it.

Good luck

so how come torque for rear caliper is as tough as front one for turbo. the rear handles about 10% of braking power.
