Hi, looking to replace my rear pads and discs this weekend myself. Feel pretty confident and i've got a mate helping. One thing tho, my haynes manual says I'll need to replace the 'guide pin bolts'. So what I want to know is: do i need to do this, would they be supplied with the pads, or where could i get them from? All help info and tips appreciated re this job. Thanks If it makes a difference it's on a 2001 TDI 130.
