Apologies for resurrecting an old thread, but...
My disks and pads have been on the car for a long time now, but recently have developed a distinct judder, pretty much as described by the original poster on this thread. I can't see any obvious flaws or excessive wear on the front of the disks but have not been able to check the rear faces.
I have a set of replacement pads ready to go on, but the ones on the car don't seem to be too far gone at this stage. Is it worth trying the bed-in procedure with the existing pads or is the general opinion that it would be better to instal the new pads first?
