just wanted to get peoples opinions on changing the disc brakes, because i had a look for a new set the other day and found that for the front i was looking in the region of about £200 and the rear was about £60 (brand new). which put me off a bit, so my question really is, is it worth buying new ones or should i just hunt around on ebay for some used ones?

 

I've only ever used second hand ones and never had a problem... get em for cheaper on ebay as well. Just make sure they have plenty of wear left and the price reflects that.
