C3:Parking brake shoe anchor bolt torque?

[Steve L.]

Can't find this spec anywhere. It's not in either service manual.
I'd appreciate this torque.

That is a 1/2-20 bolt, I never found the spec either. I drive them on tight and use a new bolt lock tab. You can use a drop of 242 loctite also.
Chase the threads as many are rusted and tight.

Thanks,
1/2-20 bolt max torque is about 140 ft-lbs. This seems really high.
I was going to put on some copper anti-seize and a new lock tab. Rather than loctite.

That bolt just holds the anchor in place on the bracket. No real load on it 140 is too much. I may use antisieze on some but never had a problem removing any yet. I use AS on the star wheel threads and arm to frame bolts.

Typical torque on a 1/2"-20 bolt (like the BB balancer bolt) is 85 ft-lbs. - 140 is WAY too much.

In the 1973 Overhaul Manual, in the specification section, they list the brake anchor bolt for Chev, Chevelle, Camaro and Nova all as 120. But these are for the regular drum brakes. Corvette spec on this line is blank.

I think I'll try the 85, sound like a good number
