front dr side wheel noise - screeching fades when turning

I recently bought 96 Honda Civic for my wife, but I drive to work.
About a week ago a scrreeching (metal on metal) noise started very
quietly and it's been getting louder daily.
But it doesn't start until I've driven about 3/4 miles and then it
slowly gets louder and louder BUT when I apply the brakes or do any
sharp turns it fades or completely disappears until I release the
brakes or straighten up.

Any ideas anyone?

Check the pads for wear - could be the wear indicator.

Check Tegger's faq:

I had the exact same noise during turns that disappeared when I
straightened out or applied the brakes. When I checked my pads they
were almost new, so no wear indicator noise. I did Tegger's brake
maintenance and it solved all problems immediately. I highly recommend
it...

good luck

Thanks for the replies.
I'll take a look at the link you posted Bruce and hopefully update this
message to let you know how I get on.

Thanks again.
