Are you sure it's not a rattle off the brake pads, Panel? I know it seems unlikely but it's quite common in Skodas... in fact if I had a pound for every taximan who's told me he's replaced drop links on Octaviaseseses only to find out the pads were knocking/rattling I'd have at least £4. Try drinving on a concrete raod surface (Millbrook Road or Clontarf Road on the Northside), roll down the winda to hear the rattle, apply the foot brake, if the rattle goes there's your problem. It's not a big deal in the Skodas, generally down to loose fitting spurious pads but they're not gonna fall out or anything, it's just the spring clips that go inside the piston, not the securing pins. Replace with OEM or Mintex/Pagid sorts it for Skodas anyway.
