Got 2 12mm bolts tapped because of previously damaged threads in brake calipers. It was great that they said they could do it same day but they told me they’d call with an estimate. They called at noon and said they were done and I thought great, it can’t be that much. It was $292 for two re threads, I’m in no way a mechanic but I do know a bit. I’m not sure how it took $250 worth of labour and $40 for parts. I just think they should have called with the estimate first, I definitely wouldn’t have got it done.
