I have just had mine fitted by @Lightly, who made a good job of repairing all my brakes and fitting new pads all round. Several of mine had seized but it passed an MOT 7 days before!
The stainless steel ones are a very good fit and replacement and are 0.8mm deeper than the original ones that were fitted. I can recommend Mark Lightfoot for any Twizy work if you are local enough to get you Twizy to him. It wa
s nice to see another Twizy as we were both parked together at his workshop.
Thanks @Lightly and @ALEXAKOS
