no they dont but since this is the first one i saw im gonna help[ ya out
well obviously you need a new disc and maybe a new caliper and a caliper pin (depending on the damage you might not need it.
You could always take it to a shop and have them fix whatever the problem is because they would have the knowledge of what was damaged and what isnt (Im guessing you dont know). Or get a cheap manual and fix it yourself on a weekend, then when youre done w/ the book return it and get a better one (Helms Manual) just be careful not to get the book dirty so you can return or even exchange it.
This is the best advice I can give or think of without seeing the damage first hand (no a pic really wont help), sorry and goodluck. Get it fixed ASAP though!
