Torque specs for Caliper halves bolts

Rusty

I know there is no markings on the bolts for what grade they are. I don't think Nissan would use the lowest grade, or the high grade bolt for this application. So I picked one in the middle, which would be 8.8.

The torque reading you are getting fall in line. Remember that you are not dealing with everyday bolting. This is Nissan speced. So the head size may not be what you are expecting. Car companies do some strange stuff.

I've rebuilt 4 sets of calipers so far. Of that. 3 had some type of thread locker on the threads. Most likely a triple boiled linseed oil. When I worked for Elliott TurboMachinery. We used to use this stuff all the time. Great thread lube until it drys.

Since the chart I linked to doesn't work. What chart would you use? And what torque would you use?

I hate to tell you. Those calipers in the video. Already have been apart, and cleaned. Plus when he took them apart. Where's the brake fluid? They have new pistons and seals already in them. The threads on the bolts have been wired brushed. The guy just took one side apart as a show and tell. He already screwed up in that video. He didn't put any brake fluid on the o-ring that goes between the halves.
