had some new black diamond discs and pads fitted tuesday and they are great, today though they have started squealing really badly, like REALLY badly, i have been easy on them , is this normal and just part of the bedding in?

 

Bed them in proper pal.......get some good speed up on a quiet road and brake hard......do it a few times

 

did u fit them? If so, use plenty of copper grease in the appropriate areas? clean everything up properly first?
