Doing brakes for the first time on my G37S. I made a stupid mistake a loosened the wrong bolts on the caliper. I snugged them back up, but can't find the torque spec in the FSM. The BR section shows those bolts on the caliper, but doesn't provide any torque spec.

Anyone know what the proper torque spec is for these two bolts?

 

Ah, found my answer over on a Z forum. Those are bolts holding the two caliper halves together.

Torque specs for Caliper halves bolts - Page 3 - Nissan 370Z Forum
Front Caliper 17mm bolts: 69.2 - 93.6 Newton meters (51 - 69 ft-lbs)
Rear Caliper 14mm bolts: 32.0 - 43.3 Newton meters (24 - 32 ft-lbs)

 

Here is an excellent guide to show you the correct bolts/procedures:

 

That's pretty grimy. Have you considered rebuilding them?

 

Frequently, lol. I'd like to have them powder coated but struggle with the idea of how much it costs just to add a little color to the car. For now, I am just doing the pads and rotors. I might consider a more in-depth disassembly and cleaning over the winter.

Next question: what's everyone's strategy for getting a torque wrench on the lower bolts on the rear calipers?

 

Ah, found a solution for the lower rear caliper bolts. If I use a shallow 3/8" drive socket, then I can fit an extension over the traction arm. Sometimes I need to talk out loud (or on the internet) to find a solution.

I found references to people just using a box wrench, but I like putting a torque wrench on important bolts. Found others using a crow foot wrench, but that seems like an easy way to strip a bolt head.

 

Stuff like that, it's best to use a 6-point socket. Glad you got it figured out.

IdK where you are, but socket67 found a great, cost acceptable solution for painting the calipers (in California).

 

I am up in the PNW. I saw socket67's thread on brake color, but haven't been following. I'll take a look at it, thanks.

@socketz67 found a guy who does this on the car, at your location, and has done it enough times to bring some solid skills to the project. Pretty darn impressive, and very reasonably priced.
