Greetings all,

I searched and didn't come up with this specific information. Any help or direction will be appreciated.

I'm getting ready to change pads and rotors on my 2015 IS350F RWD. Does anyone know the proper torque specs for the caliper bolts and the caliper bracket bolts?

Thanks!

oh wow no replies.... I'm in need of specs too.

Unfortunately with this posted in the Suspension and Brake section it likely got buried under other threads.
General forum would have yielded a response.

Front caliper to knuckle bolts - 100ft.lbs
Rear caliper bracket to knuckle - 92ft.lbs
Rear caliper to bracket - 20ft.lbs

does this torque spec also apply the the 2014 is350 fsport, AWD model for the rear, i.e. 92ft-lbs for caliper housing bracket, 17mm bolts?

zipexus

I would assume so because the brakes should be the same (large aluminum fronts, dinky Camry-like rear which btw has the pads utilizing only 80% of the rotor’s surface).

Rear 2016 IS300 awd fsport

The torque specs above apply to all 3IS regardless of engine or drivetrain...except the IS250 AWD/RWD.

ok, thanks... back to it.

What about the 2014 is250 rwd? what are those specs out of curiosity? Just did mine yesterday and want to make sure im on spec

Sasnuke

Here are the specs for IS250...doesn't matter if AWD or RWD:

Front caliper bracket to knuckle - 100ft.lbs
Front caliper to bracket - 25ft.lbs

Rear caliper bracket to knuckle - 92ft.lbs
Rear caliper to bracket - 20ft.lbs

Thank you but you previously said those numbers did not apply to the is250. Is this still accurate?

Sasnuke

You will notice that there is an additional spec for the front of the 250, which does not apply to the other 3IS models.
The rear specs are the same across all models of 3IS even thought the rear brackets and calipers are different on the 250 compared to the rest of the model line-up (which are all the same).
