This is the order I did for the brake flush before the track day, and the power bleeds I did after to try to solve the issue.

For some reason, the GM GDS2 automated bleed procedure has an order of LR, LF, RF, RR, and the abs module only activated audibly on the RF and RR calipers... So I followed that order during the automated procedure.

After each automated procedure I did the usual RR, LF, LR, RF order with the motive bleeder & some extra pumps of the pedal.
