Default Brake Torque Specs

Does anyone have the brake torque specs for the front and rear caliper and bracket bolts for a 2017 RX350?

The front and rear mounting bolt torque spec is 25 ft lb. This is from TIS for 2016 - 2020 RX.

Thank you! Do you happen to know the torque specs for the larger bolts for brackets for the front and rears?

The only specs I could find in the TIS was the 25 ft lbs.

To be honest, I have never torqued my brakes....just got them "snug". Ironically I torque most of my other specs, esp those with crush washers to be sure that they compress, but never on brakes....and never had an issue.

I’ve had bad luck in the past. One bolt snapped and another one backed out. So definitely going to play it safe going forward and it gives me peace of mind.

77 ft lbs seems to be a realistic number on similar platforms from what I can find so far.

Default Torque specs for electric parking brake motor replacement???

Can someone please tell me what the proper torque specs are for tightening the electric parking brake motor to the rear caliper on a 2020 RX350? Try as I might, cannot find this anywhere.

Thank you very much for your help.

I think that this is the spec that you are asking for....

Per TIS "Using 5 mm hexagon socket wrench, install the parking brake actuator assembly to the rear disc brake cylinder assembly with the 2 bolts and torque to 8.4 Nm"in
