What is torque for caliper bolts?

[MichaelUD]

I'd like to know the torque setting for front and rear calipers: 1976 911S. Thanks

[MichaelUD]

Okay. Where can I find the torque specifications?

On a 986/996 it is 63 ft/lb. That should get you in the game.

[MichaelUD]

Many thanks.

Not sure if your '77 will be the same as my '87

Front 52lbs
Rear 43lbs

Hope that helps.

I'm not claiming to be an expert, but that 80lbs seems way high to me!

Bentley manual is where I came up with 52lbs on the front and 43lbs on the rear.

Maybe the SC has different settings though.

I think I'd try and find the actual settings for a '77

My bad, that was a typo, its, 70 ft/lb. the 77 uses the same caliper as an '83

front 70nm for the M12x1.5 bolts
rear 60nm for the M12x1.5 bolts

Bill, are you sure its, nm and not ft/lb? Bob's article on Pelican quotes ft/lb

the spec book says nm
70nm = 51.6 ft-lbs
60nm = 44.3 ft-lbs

Maybe there's a discrepancy in Bob Tindel's article. He's got, " Remount the calipers on the car. Check the piston angle one more time. (Figure 15) Torque the caliper mounting bolts to 70 ft/lbs."


Can't argue with the spec book.
