Not sure if anybody with track bikes on here but i’ve Just listed a full PFM brake kit on eBay including master cylinder, narrow track discs and six pot calipers, will fit 08 blade onwards The full kit with master cylinder would cost over £2200 I would take £750 for the lot Calipers could do with new pads, sbs do a full front set for around £50 Gives loads more power and feel than standard kit or standard calipers with brembo master I used this kit on my track bike for 12 months and it was 1 finger braking all the time even when hot Doesn’t have to be just track bike if someone is looking to bling up their road bike but bear in mind the disc are ductile iron and will show rust if left wet, this will clean up as soon as you use them but they do really need to be kept hot to make them work at their best Links below https://www.ebay.co.uk/itm/382636038267?ssPageName=STRK:MESELX:IT&_trksid=p3984.m1555.l2649 https://www.ebay.co.uk/itm/382636057174?ssPageName=STRK:MESELX:IT&_trksid=p3984.m1555.l2649
