Donavan, I hear ya and wouldn't sweat it - the sensors break all the time during a gear swap/brake work. I should have worded my above-post better. A lot of times with something like that, you kinda gotta eat the cost but it probably doesnt hurt for someone to ask.
If it wasnt due to the machanic's inattention/crudeness (not the case here), then there really isnt much one can do.
Now that brake kit sounds yummie!
