Front Brake Caliper Bolt Torque Spec
I have been looking all over the place for this info and I am surprised I can not find it. I am looking for the torque specs for the caliper bolts, they are a 19 mm bolt head. I am assuming around 80 lb/ft? A 2007 LS 460,. By the way does anyone know where I can buy the shop manuals for this care, I am sure they are inexpensive.
Thank You in Advance

Thank you for the info. It definitely does not give a reason why I would want to replace the bolts? Usually there is a note stating that the part must be replaced ie torque to yield type of bolt. I guess I will call Lexus in the morning and hope they have this bolt in stock. I went to that site and signed up, that link you sent me will help to navigate their site. Looks like a good site good call.

Caliper bolts
I changed the front rotors due to the annoying "warped disk sensation". The caliper bolts have a red substance on them. My suspicion is the red substance is a thread lock that allows for a lower bolt torque. So I advise everyone to change the bolts after removal and we need to get the exact torque spec. Safety first fellow members.

I'm willing to bet that the dealer doesn't take a torque wrench to the caliper bolts or the lug nuts yet people think they are the experts on everything Lexus.

That red substance is thread locker. I bought Toyota flywheel bolts on my other car that came equipped with that stuff and those bolts needs to be replaced because they stretch when they reach their final torque.

I just had a look at my alldatadiy.com account and can confirm that number and also that the bolts should be replaced.

Wow! I've never heard of caliper mounting bolts needing replacement after use. This is a new one on me - I guarantee 95% of the automotive world didn't realize this either - which means there's quite a few 460's driving around with bolts that need replacement.
I'm sure they're probably fine, but I find it interesting they call for them to be replaced.

Why don't Wheel lug bolts call for replacement? I looked up several other car forums on this and only BMW and a few others mention replacement and the remainder did not require it.

There's no shear force on these bolts as far as I know, which causes me to wonder why they would need replacement. At only 100 lbs/ft of torque, how much stretching is there?
