88 can use pressure when the nut and lever are removed.
Problem is 88 cast iron piece blocks a normal C clamp.
If you try anything else then make sure pressure doesn't load the piston unevenly etc.
GM made a tool for 88 that turns and
put pressure on the piston w/o removing nut and lever.
Pressure is needed to turn inner piston and not stripping piston holes on front.
Good piston needs very little force to retract.
Dr. Ian Malcolm: Yeah, but your scientists were so preoccupied with whether or not they could, they didn't stop to think if they should.
