as far as cost the disc will run you anywhere from $150-$600 depending on what you get, check
www.hparts.com/part.html and maybe you can get OE honda at a better price (you will not get a good deal at a dealer unless you have connections) The caliper will cost around $50-70 single and double that if they come in a set, call your auto parts store (AutoZone, if there is one near you, will have them at a decent price
) Im not sure if a new pin comes w/ it or not, but it probably does, if not it cant be much more $.
As for the rim...its your call, is it bent enough to make it dangerous to drive? But I say if it was enough force to smash the disc then its probably not safe to drive on, if not for long. Id put the stocks on until you get a replacement rim.
Hopefully there isnt anything other than those things that are broken. Since I cant be there to look at it (or anyone else here for that matter
) I would definately advise you to take it to a shop ASAP, Midas (and tons of other multi purpose shops) do free brake inspections and since it is a brake problem they should be obligated to check total damage for free and give you an estimate on pricing (parts plus around $80/hr labor). They are also obligated to tell you what is wrong exactly w/ the parts and tell you what needs to be replaced. I would get a quote from wherever you go (w/ the parts needed to be replaced listed) and call around or even go to your local auto parts store and buy everything and do it yourself (if you feel comfortable doing it) or w/ someone that has expirience.
Good luck w/ it
