Why the steering wheel shakes when you step on the brake pedal with new brake pads of Honda Acc 01 do you need to change the disks or do the bleeding?

Sounds like you didn't have the rotors turned when you replaced the pads. Either have the rotors turned down, or replace them with new ones and the shaking will stop. Also make sure there is nothing between the rotor and the hub, this would cause a problem as well.
