You can sue them for the damage that was done but you need evidence that they have fitted the incorrect brakes and that was the cause of the damage.
You will need to get a report form an independent repairer to say that it was the break pad that were the problem and what the cost of the repairs will be,
The you can send a letter of demand to the person that fitted them and ask them to pay the cost or you will sue.
The following link explains how to sue in QLD and the process.
