E-brake adjustment???
The adjusters are in the rear on each side of the rotors. Remove the caliper one side at a time. Then remove the rotor. On the bottom of the rotor backing plate is the adjuster.
When I adjust mine I set the ebrake to 4 clicks and then adjust the adjuster until that 4 clicks holds the rotor in place. Then I put that side back together and do the same for the other side.
Once both are done I make sure the 4 clicks holds both sides then make sure the car will not roll once it is back together.
