I don't think that it is fair and/or reasonable to ask anyone to specify the exact parts that you should be buying, the next thing that could happen is that if you or your mechanic mess up this brake change/
service, then public finger pointing can end up kicking off.
Asking for general advice is okay, but not down to the exact ebay listing etc, well that is how I think of this.
As you have already said that you don't know anything about brakes etc, why don't you let the
workshop that you will be handing your car into to pick what they are comfortable with fitting?
