If that link works out of the bracket the caliper carrier will rotate forward during a stop resulting in a very loud thud. Repeated stops will likely damage something. Once you remove the single remaining bolt from the cap you will probably need to tap gently to doslodge the cap. Once the cap is off you should be able to get a purchase on the remaining stub of broken bolt, may even find it to be finger tight.

It is tight quarters but I did the rethreading with everything in place. To remove the caliper carrier you have to pull the axle, a much bigger job than I intended to take on at the time. As I posted in the link, when you are reinstalling that cap it will not sit flush, you have to start both bolts and tighten evenly. Basically pressing the cap over the link bolt.
