Auto Insurance Claims: Faulty mechanic work, front brake caliper, brake pads and rotors

Question
I recently serviced my car and replaced all my brake pads and rotors.  When driving home my brakes seized and I later found out that a bolt was missing from my front brake caliper.  The mechanic said their work was insured and is willing to replace the caliper for me.  I no longer want to have the work done by that mechanic and want him to pay for the broken parts.  He refuses to pay for the parts and insists on fixing the car himself.  What are my rights, what should he be liable for?  Thanks, Luis

PS I'm not sure I'm asking this question in the right forum, but this was the closest topic area I found.

Answer
Hi Luis,
In most states, when a shop 'insures' or 'guarantees' their work, it is normal and customary that they be allowed to correct the problem.
Your rights for a refund would only apply if the shop refused to correct the problem.  If that happened, you could file small claims court action against the shop.

I hope this information has been of help.
