Hi guys, I have noticed some rust forming in the head of some bolts that hold together the brake pads and others. I am assuming this is because of the times I have gotten caught in the rain or ridden over a wet street.

My question is, can these bolts (the ones that came with my Allez) be replaced / upgraded with Ti- or alum or some other bolts that do not corrode? or is this just a maintenance item that will need to be replaced every year or so?

Most likely you want Stainless Steel bolts and hardware. Ti or Alum are not good fasteners for this application.

^ okay, and is something that I can go int my LBS and ask for? for instance does ultegra calipers come with SS hardware?

Replacing your calipers to get new bolts is a bit overkill. Try here: https://www.mcmaster.com/#machine-screws/=4xj2go

i was asking in the sense that if I get new calipers (nicer ones) will they come with SS bolts.

It's where you live, just the humidity and salt air will rust bolts, particularly if they're scuffed.

Ti bolts work fine. I have them on stems for this reason.

Also, you can put petroleum jelly, or wax inside the head of the bolts, or you can just live with the rust.
