Re: put lift on: temporary brake failure
Unless you let the master cylinder go dry while you have the brake lines off, there is no reason to need to power bleed. This is only required when air gets into the ABS system.
Another option four the caliper hitting the control arm may be to trim it. If you were to trim you may need to box the control arm though. This way you still have your steering radius {Extremly important here in Washington)
