Hi,

what is the torque for the brake caliper bolts for both fron and rear in
2002 Outback?

--
thx, andyl

>From the 02 Impreza repair manual:

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)

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.

I think the difference has to do with the engine power. Remember that
the brakes have to be strong enough to overcome the power of the engine.
The larger the engine, the bigger the brakes. That of course relate
to the expected driving habits for the car.

Yes, that explains the difference in the size of the rotors. I'm not
sure it explains the torque specification on the bolts though.

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.

Bolt size and grade are the same for the front and back?

I am not entering in a pissing contest with you, sorry
