250-500cc Front brake master cylinder rebuild kit

Does anyone know where to find a master cylinder rebuild kit for a 2009 WR300? I've had no luck. I had someone ask if all of the Brembos were the same. Does anyone know if that is true?

Hi there, I checked the ProX catalogue and they are not sharing a part number for the WR's so I guess something is different on those masters , probably the piston body itself having a different engagement with the lever , but you could probably get a rebuild kit for some other bike brembo's with the same diameter as yours and just swap over the little seals and use your actual piston...

On the other side, it looks like the OEM rebuild kit is still available from my local shop here in Spain:

Fun part, they are referencing also a KTM part number:

And that one I can find more easily on other sites as well: https://www.motocrosscenter.com/shop/en/18/293586-cylinder-kit-master-54813008200.html

Cheers.

All the brembos are not the same. I have several of the 125 specific one that Hurky is calling out. I also have an older one that I think was from my 06 WR250 and if that is correct then I have what you need. You really need to pull the plunger out of your master cylinder and take measurements and if possible post a picture that way I can confirm that what I have works. If it does I will hook you up.

Hi,
I have the necessary parts available on my website:
