I do recall finding a .pdf with torque specifications for nearly every bolt on the SC300/400 series but do not seem to be able to find that. Would anyone else have that file? I am specifically looking for the torque spec for the brake caliper, not the one that connects the inside piece to the outside piece, but the main 17mm bolt that connects to the mounting assembly. I sure hope I used the right terminology. Any input is appreciated.

But in general, it would be nice to start up a thread with torque specifications for common bolts found on the SC and perhaps even for Lexus in general. Apologies if this thread has already been started.

Caliper bolts have a torque spec of 25 ft. lbs.

Serious? I remember having an incredibly difficult experience in loosening that bolt! Maybe because I'm using a wrench about 1/5 the length of the standard torque wrench (wherein 76ft-lbs is a piece of cake). Thanks for the reply.

So maybe I will start off the list and when there is a generous amount then it can be pinned; please feel free to add or correct me.

Wheel lugs: 76ft-lbs
Oil Pan: 85ft-lbs

25 ft. lbs. for the actual caliper, 87 ft. lbs. for the caliper bracket
