Where aren't pads pre-beded in?

Why don't brake manufacturers bed in new pads? And what does bedding in actually do to the pads (other than make you stop faster), I'm sure one of the sets of instructions I had said it removed solvent residue from the manufacturing process? Just questions that have been floating round my head for the last week or so (fitted four sets of pads in the last week).

Seems to be a bit like buying a new bike but having to cure the paint before you can ride it (sorry couldn't think of a better analogy).
It's easier to ask for forgiveness than for permission.

I've bought a new bike....ouch - result
Can I buy a new bike?...No - no result

    they can not. bedding in is the action of the pads on the disc. they dont know which will be used with which.

    it is not like it is hard to go for a gentle ride to bed them in is it.

    Even if they could do it, would it be worth paying the extra for them that the higher manufacturing cost would guarantee?

    I'd rather pay less for them and do it myself.

    but you miss the point it is NOT possible. as it is the bedding of one pair of pads in one particular caliper mounted by Fred to frame x or fork y to be used with disc Z.

    It is just like a car, these need to be bedded in as well, as Nick says, it is not possible to have pads bedded in, as they bed into the brake surface. Also pollutants in the manufacturing process need to get burnt off.

    I thought it was linked into gradually heat cycling the pad material?

    I didn't miss the point. I was just saying that even if it was possible, I'd rather they didn't do it anyway.
