Hi,

like the subject, what is the best supplier or are genuine Yam parts still on stock ready to purchase ?
I only find the brakemaster parts, eBay and most online shops leading to this brand.
But in my case, they don't seal. The right caliper, the second peace and third trial continues leaking with new rings.

can anybody of you recommend another brand for the piston seal rings and pistons as well ?

Thanks

I stick with OEM for brake stuff. If it leaks with the proper seals then you probably have some fault with the caliper itself..?

Not heard any bad reports about Brakemaster, have you tried contacting them?

Otherwise you could use their rebuild service to ensure they are responsible if it still fails?

In the past, I've good success using PowerHouse kits from UK (ebay only shop  :( at this time).

It seems that they have an online shop now (but not verified myself)
