I started reading this thread when it first started and said to myself, "self, don't know what the problem is, I've never had a problem." As things go, those were famous last words.
A few Days before reading the thread (September 19th), I ordered some Caliper rebuild kits (O-Rings) for a buddy of mine with another brand bike. This past Monday (September 29th) I checked the tracking on the part (on USPS web site). The package had received scan notification on September 20th but nothing after that.
Contacted the seller diparts I believe is their name. And they replied that the part had shipped and would find out what's going on. Meanwhile, I've got the calipers ready to rebuild and still have no O-Rings. and no further word from the seller.
So, I guess I cursed myself. LOL
