I am having touble searching for one for my buddy , his quitpumping fluid, I think the seal in there is shot or gummed up. any info would be appreciated thanks.
Presumably you are looking for an alternate source besides a Husqvarna dealer... I started typing 'brembo' in google and found this, perhaps? http://www.brembo.com/US/Motorcycles/Distributors - West.htm
I bought a replacement brembo piston kit from partspitstop.com. The part number is 50313008300 It is listed to fit most KTM EXC model bikes with a brembo master cylinder, It's $20. I replaced the o-rings on the caliper first and that solved my mushy brake, you may want to consider that as well.
My Brembo front caliper seal kit showed up yesterday for my SMR450 (P4 production radial mount 100mm caliper). Seller states that seals themselves are Brembo. Reseal task was a snap and so was bleeding process. Kit was not cheap, $62 counting shipping, but a lot cheaper than a new caliper which was $350. Not sure how this compares to kit from Yoyodyne that they are always out of. Same caliper installed on assorted other Italian stallions, often in tandem. The sellers name is Powerhouse out of Yorkshire, GB, they have an ebay store.
