Had a nice conversation with Ross on the phone just now. Not trying to turn this sub-forum into an extension of the Marketplace, but I just had to pass this on to everyone considering buying a brake from Ross. He will make you a thread protector to go with your brake if you want for an extra $5.00! Just ask.
He thought everyone here knew that already.
EDIT: It didn't occur to me to ask him if it applied ex-post-facto.
