Hey guys,

I'm relatively new here. At the end of October I picked up a 2015 250 F Sport.

I'm considering replacing pads and rotors. I've seen lots of posts talking about how easy both processes are, but I'm a bit confused. Some are using anti seize lube, others don't. Some say to put lube on the caliper piston other say absolutely not. Where exactly does lube need to go? As far as I can tell there are 3 places. What am I missing?
1) Between the shim and the pad
2) On the caliper pins
3) Between the "wheel" and the rotor

Also, I'm looking for information on torque specs for the screws / bolts / lugs we're removing.
1) Wheel lugs - 100 fp?
2) Caliper pins front and back???

Thanks,
Ben

I would read the manufacturer directions for the pads, parts, etc. The locations you mention, as a general rule, are OK in my opinion. Particularly between pad and shim and wheel and rotor,however use very very VERY little on the wheel and rotor. Make sure you get NONE anywhere on or near the studs or any other fasteners.

As far as caliper pins, I'm not sure what Lexus recommends, but BMW recommends installing the pins DRY. Just to give you some perspective some manufacturers do not like it. If it were me and I was doing the job, I'd install them dry unless I had specific instructions from Lexus not to. Pull it apart and see if it seems the factory installed any grease. If any, copy it and install grease.

The aim of the lube on the pad hardware is to eliminate high frequency vibrations which causes squeaks. Generally you do this on the bracket and bracket guides for the pads. And some on the shim where it touches the pad. You can smear a little on the piston face itself.

Whatever you do, less is more. Don't want the stuff dripping on the rotors/pads.

Thanks for the reply. Do you have any idea how I find out what the torque specs are on the parts I need to disassemble?

Also, I just found these videos VERY informative about where to lube and what with...
