How hot is too hot for a new set of brake shoes and drum to run???

Unless the drum is red hot and smoke rolling out, you should be ok. I've done the same thing your doing with a temp gun after changing shoes and drums, and I got the same results your getting. Some of your s cams or bushings could be more worn than others allowing one wheel to do a little more work even though slack adjusters are adjusted the same
