rear brakes won't bleed

The brake imbalance switch is self centering, it doesn't need to be re-centered as do gm and ferd stuff.
If the switch didn't self center, - every time you used linelock, you would have to get outta the car to recenter it, that's why the dash brake warning/imbalance lite goes out when you release the l/lock switch.
The 2 springs center the shuttle/switch.
You guys work on too many alternate vehicles, lol
