That is great info, HH56!!

I'm wondering:

Is the cause for many failures of BTVs this pitting in the casting around the piston seal, perhaps?

Further, do you suppose that neglecting to repair this pitting condition when rebuilding could be the cause of many failures after rebuilding?

I'm only speculating, but, especially if the brakes are not used for an extended period, moisture might creep in between the casting and the seal, possibly leading to pitting. Also, I would think that the metal around the seal where it meets the casting is of a different metal than the casting. Could there be some chemistry created that leads to pitting?

I'm only asking, but this should be considered, I think.
