How to size for a front disc conversion?

I have a bike with a front shock and want to convert from V to disc. Does the shock disc mount have anything to do with the size disc system I get? I know I will have to buy a new front wheel with the correct hub but beyond that I am not sure how to proceed.
Thanks,
Keith

If your fork is disc compatible there will be two mounts at the bottom on the left stanchion. You will need to get a caliper mount for the type of brake that you want to use (Avid, Hayes, Magura, Formula, etc) to match the size of the rotor that you want to use up front (160mm, 185mm, 205mm). After that just pick up a wheelset with either the Shimano centerlock or ISO rotor mount and you're set for some real stopping power. Personally, I run a 185mm on the front and a 160mm on the rear.

The brake caliper is generally the same for all rotor sizes. The adaptor used to mount the caliper to the fork is size specific as it spaces the caliper the proper distance from the axle centerline. This way, you can move the brake system from application to application with only a change in adapter. (and the rotor too)
