Just wanted a bit of advice really. I fitted a new front wheel the other day and when riding to work yesterday, I noticed that there was quite a nasty griding sound coming from the brake and there was also some metal shavings (like from a lathe) on my brake pad. I had a better look at it on my lunch brake and noticed that there was quite a few bits of metal in the brake pads and also that the braking surface has a bit of scouring and a few nicks on it. I cleaned the rim and got all the metal from the pads but when I got home there was another big chunk of metal in the right hand pad.
I've since ordered some new brake pads but was wondering what to do aboput the braking suface to smooth out the scouring and nicks? Would a rub down with a very fine peice of wet and dry be OK or a sharpening block or will that ruin the rim forever?
I'm a bit concerned as the wheel is literally 4 miles old and don't want to have to shell out for another new wheel.
Any help is much appreciated.
