Pebbles in brake pads

Just wondering how you guys prevent small pebbles from embedding themselves into the brake pads and scoring the alloy rims? I just went out on my new/old Univega and within blocks had that gawd awful scraping sound and had to release the cable(s) and pick the pebbles out of the pads (this happened on both the front and rear pads at different times).

It currently has some old knobbies on it which I'm replacing with some nice slicks, I was thinking maybe the style tire that's on it are kicking the pebbles up into the brakes? and the pads on it are no doubt the originals, though they seem to be supple rather than hardened. Any tips? Thanks in advance.

Attached are a couple pics.

there is really nothing you can do to prevent it from hapening. if you ride in rainy/ wet weather just be sure to clean them often.

and as posted above you may want to consider new pads.

I use and like swiss stop black and/or green brake pads. It is a little bit more expensive than kool stop pads, but I think it's a little bit better on your rims.

I could never get the kool stop black pads to work well for me, as the bumps on them are a pain while mounted.

I took some emery cloth to my rims to remove the scoring, and bought some kool-stop brake pads and the problem vanished! It must have been aluminum shards as mentioned. Thanks to all that replied.

You're not the first nor will you be the last one to find out just how badly Shimano pads are.

Agreed, The kool stops I have are awesome...so quiet and great stopping power from the start. I'm going to have to get some for my road bike now.
