It depends what the problem is.
If they are the only one who has touched the car, and there is a part missing, or if something not right, then yeah I would say they will have to eat the costs. If it's a caliper like before, then yeah I'd say it should be covered.
About the only thing I w0uldn't think would be covered would be a wear item, lets say you need new pads, that wouldn't be covered. But without taking it in there and seeing, or looking yourself, it's hard to say.
