Probably no more so than any other mc piston.
When discussing the BTV IT is absolutely critical that we keep in mind that the btvis very different in deaign than probably at least 90% of ALL other master cylinders EVER BUILT BY ANY COMPANY AT ANY TIME.

With that the pitting of the btv piston is most likely due to the fact that the piston EEXTENDS NEARLY FULL LENGTH OUTSIDE of the mc housing. This is NOT typical of the typical mc, 1956,1928 nor 1988 or any year u want to pick.
Because it extends OUTSIDE of the.mc housing it more subject to atm.

The other pronlem is that the piston is supported at a fulcrum point by thw inner seal. Again this unlike more commonly found mc's. Bottom line the inner seal is taking all of the support for the piston. Which means very possibly short service life of the inner seal.
