Does anyone know where to get replacement OEM brembo M4 34mm caliper pistons from? I've stripped my calipers today (as part of a complete bare frame restoration/rebuild) and a few of the pistons have very slight pitting it seems the brembo P/N for the seals and piston kit is 205474773, however I cant see any UK/EU sellers Thanks
Yes, there is dealer selling through eBay and there is an organisation who offer refurbishment that I used but that cost an arm and a leg and I could have bought good quality used units for less. I’ll see if I can dig up the details. Andy
https://www.ebay.co.uk/itm/154404378630?hash=item23f337d806:g:CQcAAOSwONlgbFmd I've seen these, but they're not genuine seals and they're aftermarket stainless pistons whereas the originals are aluminium ideally I want a couple of these kits from a UK/EU source https://www.motoworld.com.sg/brembo-205474773-kit-piston-and-seal-m4-204474773
I had to replace the pistons on my Girlfriend’s Diavel M4’s because the aluminium pistons collapsed having rotted through. Pretty sure there are pictures on here somewhere. I had no issue with the stainless replacements or their ongoing performance. Andy
Not uk but these do nice pistons and seals kits too. https://mcet.de/eshop/en/brake-syst...um/caliper-piston-titanium-brembo-m4-calipers
