mine worked for about 3000 miles... adjsuted them for the trip to WDW in June.
but i never use it and when I did go to use it again it didnt; work anymore.
Dunno why the installed one assembly upside down where invariably it will vibrate down and wear the pads.
Oh yeah I do... it saved $3.00 per vehicle.
What I did was put the foot pedal partly on, adjust them till the rotor just barely wouldn;t clear and then release the parking brake and re-assemble it.
Absolute shit design though, especially having one inverted just to avoid needing mirrored parts.
