It sounds like your caliper pistons are indeed crudded up. It's an easy job to fix them. You need to pull the calipers from the bike, loosen the banjo bolt before pulling the two caliper bolts on each caliper. You can force the pistons out with compressed air after removing the pads, or you can remove the pads before removing the brake line and push them out with the brake lever and pedal, but this can be messy. Make sure you don't get fluid on the paint, it eats it. Once the calipers are off and the pistons removed, clean everything with brake cleaner and inspect the caliper bores. If they look okay replace the dust seal and piston seal in each cylinder, after soaking the new rubber parts in brake fluid which should be DOT4, wipe the cylinders with fluid, wipe the pistons with fluid and put things back together. Make sure the caliper bolts and bushing can slide back and forth freely.Once back on the bike the caliper itself should be free to wiggle sideways otherwise the pads will wear very unevenly and may drag on the rotor.
Bleeding out the brakes should finish the job. When bleeding the rear brake remember the front left caliper is also hooked to the pedal master cylinder. Bleed the front one first since it's the farthest away from the master. Shouldn't take more than an afternoon to do the job the first time.
