Basically I brought some st170 brakes calipers,turned up today but didn't come with the carrier's ,so I messaged him and he replied saying it didn't say they came with them and basically it's my fault.

If he stated that they didn't come with them I wouldn't of brought them.

 

Were they in the picture? As in my opinion if they wasn't I don't think he is in the wrong.

 

No you couldn't tell from the pic that they weren't there

 

As above, never assume anything with eBay, if they weren't listed as with carriers then it's not really his fault.

 

If he advertised the calipers and you got the calipers then I don't see what the problem is. If he advertised the calipers and carriers and you didn't get them, then I would be pissed!

 

I'd agree with the seller!

On the other hand, Do you do understand what brought means?
