    My front discs are starting to warp, giving a bit of brake judder, and been told to replace them before the next MOT. I’ve got the standard ‘snowflake’ design but can’t seem to find anyone that sells them, so assume they’re no longer available. I don’t take the bike on the track, so fast road use only. What would you recommend replacing them with?

    Thanks
     
  2. disc doctor may be able to help you.. think they can supply new rotors for your carriers. never used em but just seen em advertised.
     
  3. Give the bobbins and carrier mounts a good clean. Tight bobbins are far more common than warped discs
     
  4. Thanks, hadn’t realised that made a difference, will definitely do that before looking to buy new ones :upyeah::)
     
  5. I'd go for the brembo series oro discs if you do need replacements.

  7. I made a bunch of the disc carriers and in the slightly older style. as long as the discs are true, quite often the judder is down to the worn carriers, as they are made of softer aluminium. I got these ones made with T7075, so much tougher and they made a real difference on my discs. The rotational wear is the biggest problem, when combined with the side to side "float"

    Mine are the 12 bobbin discs, rather than the 10 bobbin ones that I think you have on your bike.

  8. Not all bobbins are hollow so this method won't always work.
    Mine are solid.

  10. John, if its any help the ones fitted to the 748S models are the same as the standard ones on the 996s and some Monsters but are not the same as those fitted to the 2001/2002 748E or 748R. There are however plenty available second hand. Part number was 49240101A but was superseded by 49240791A

  11. Thought I’d take the opportunity to service the brakes while we can’t go out. Think I may have found out why the brakes weren’t releasing smoothly one one side.... :confused: 464414E6-973B-45DE-95A6-FD667B184ABE.jpeg 36482A1B-EC32-4728-8924-CC4C2F36AB56.jpeg 31217C0A-DA68-4812-B34C-60DA78231C64.jpeg
     
  12. Eeek :scream:. Rebuild kits are available, not from Ducati, if you can identify which other bikes the caliper is used on. Andy
     
  13. I'm amazed the caliper bolts came out in one piece.
     
  14. That’s cheap, it would have been almost as cheaper to buy new M4s for the price I was charged for 8 new pistons when the calipers were refurbished. Andy
     
  15. Stainless steel pistons look really well made, nicely finished and solid. New seals installed and just waiting for some new SS bolts to finish it off. :):upyeah: 38787E5B-2A0D-413D-AA93-8A59009E13C6.jpeg 50E4F929-59D5-44F0-BEEF-B9A8AEFAFA28.jpeg D780EE45-B6D8-46F5-A944-770D3407E85A.jpeg
