When Gohan was training with the Z sword, Goku threw huge rocks at them, what do you think it can compare to for us, what it‘s like to them to carry it?A piece of paper?A small rock?or what? Same for cars with them.
If you didn't take the brake line off the caliper there is no need to bleed them. If they had air before and you want to bleed it out, it would take 2 people literally just a few minutes.
if you just changed the pads You do not need to bleed the brakes to fit the pads you had to push the pistons right back and when you have put in the pads the pedal will go to the floor just pump the pedal until it comes into Contact with the pads and it will then feel normal
Considering their strength and ease of lifting, I'm pretty sure picking up those type of items would just feel like picking up a small rock or maybe even a pebble
you don,t have to bleed the brakes if all you did was change the pads. the only time you have to bleed brakes is if you change the calipers, a wheel cylinder, a line, a hose or master cylinder. just changing pads won,t let any air in the lines.
