Yes, that's what I usually do if the calipers work fine. If they feel stuck, better open up the calipers for a deeper cleaner and eventually replace the pistons orings.
The shoelace should be soaked with brake cleaner, right? Not brake fluid!, which is highly corrosive.
Also take out the slider pins, clean them well and apply heat resistant grease.
It may happen than there is no space in the brake fluid reservoir to let the pistons back up. In that case, open reservoir cap, take out some fluid with a syringe or by dipping a tissue, and then push the pistons back in slowly and carefully not to spill brake fluid.
After re mounting everything, check the fluid level again to see if you need to fill up the reservoir. .
Finally you have to break in the new pads. Do a search on that on the web, but basically you ride the bike, accelerate to 25/30 mph, then brake to 5mph. Don't let the bike stop completely. Do it several times to let the brakes get into temperature, then do is some more times a bit more aggressively, and then you're done. That should make the pads copy any grooves that the disc may have.
