Why use several shims anyway? Get them in the appropriate thickness and change them out as need be.

So you might take up initial wear with a 0.5mm shim, replace that with a 1mm shim when the wear creates the gap and so on. And it is OK to put a 1mm shim on one side and a 0.5 shim on the other pad. But as raceinstructor suggests, don't stack multiple shims behind one pad, and don't use bent shims.

You do not need to buy manufacturers shims, they aren't made of magic metal, cut them from flat steel with handsaw and file, which you can probably get in most thicknesses from your local steel fabricators scrap bin.

But there is a limit to how far you can take the brakes, running them down to bare metal is not an option.

Most brakes (I haven't checked OTK) are held back by spring bolts and they will prevent the brakes travelling further than a certain amount.

Another thing to watch for is that the disc thins with use (you grind away the disc material as well as the brake material) and a too thin disc can distort with the heat; then you really do have braking problems.
