ABS ring cracked recently due to excessive corrosion. (Car is 4 years old 28k miles) This was indicated by tapping on the brake pedal during deceleration. Probably due to the ABS being activated when the sensor got confused as it passed the gap caused by the crack in the ring.
Initially struggled to get a replacement. (The rings are different dimensions to those used on the rear brake discs which are more commonly available) Renault were unable to offer me a replacement part and scrapyards I contacted were only interested in selling me a full driveshaft.
I contacted Reluctorrings.com and they made one as a replacement. This saved money and they claim their rings are made with higher quality steel than the originals.
The rings have to be heat shrunk onto the driveshaft (following the suppliers guide) Fitting requires the wheel hub to be taken off, the driveshaft can stay on the vehicle. I did this myself but care and plenty of time is required. A garage offered to fit the part for me for 1.5 hours labour.
Just thought I would pass on the tip.
