[QUOTE="davidd, post: 97754, member: 1177"] I am reasonably certain that Porterfield does not supply linings separately. I will ask them directly about foreign customers. One thing that can be tried is for someone in Australia who has a brake reliner is to give them some detailed information and see if they can locate the material by checking with their suppliers. There cannot be many suppliers of friction material with this high spec. I should mention here that this lining is quite dangerous if you don't have a modified steering stem. I have written many times that if you improve the brakes you will cause yourself a wobble. Unfortunately, David Tompkins did so today in practice. A rider slowed quickly in front of him and he got on both brakes hard. The front end went into a wobble and the rear brake, that had an aluminum torque stay, snapped the torque stay in half. We all want better brakes, but when they work at a very high level you will run into problems that would not happen with low performing brakes. The good news is that David rode in the race after crashing and got second. His lap times dropped another 5 seconds in the race for a total of 12 seconds better than last year. He had no problems with the brakes or corners. I will send David a new steering stem on Monday, but I wish it had occurred to me earlier. Frankly, I did not expect the braking performance to increase so dramatically. David [/QUOTE]
