G'day herb, a mechanic recommended that new rotors be installed as part of getting the RW Certificate, along with front brakes. ThankfuIly, I got there in the end. I wasn't able to test the old ones to see if they were shuddering or anything as I had a new clutch installed, before-hand. I've kept the old rotors, so I will measure them up. Thank you for your response.
Joel.
