Rear Brake problems

I am assuming the white smoke is from brakes in rear not engine. Recheck your work and see if brake drum will come off check to see if you backed off adjustment for parking brake when you redid the brakes. Then have it scanned for codes because you may have messed up an ABS sensor or something else in the ABS. A mechanic will need to scan for codes for this. Or it may need to be bled with a scanner to open all the valves in ABS to bleed air out. See picture.
