Rubbing Brakes

[DJPT]

1997 R Renault Clio 1.2 RL Paris

Recently my car has started making horrible and very loud grinding noises when travelling at 60 MPH on the motorway. When I drive in residential areas at 30 MPH I can hear the driver's side front brake rubbing as it rotates (can only hear it when I have my head out of the window).

Is this a big deal? The brakes are working fine and my mechanic can not find any faults with the brakes. He has also give both sides a good clean but the noise is still there. Might I need new pads and discs?

My mechanic said the brake discs and pads are brand new. It dosen't make the grinding noise anymore thank god, but I do get a funny rubbing noise when I apply the brakes to stop - from the front driver side.

At last, Renault in Wakefield found the problem. There was a small hole in the driver's side drive shaft - gradually the grease came out causing it to run with no lubrication.
