Can anyone help with any ideas on this one :

On the RST I have had a squeaking coming from the front drivers side wheel for a while now, and have been trying to cure it. The squeak isnt constant it only makes a noise on one 1/4 of a revolution of the wheel.

So far have check that caliper isnt seized and it returns all ok after the brake pedal is released.

There wasnt any play in the wheel bearings but took the hub off to check and found the hub was worn and there was play in the bearing when no load on the hub shaft. I replaced the hub and fitted a new set of bearings, put it all back together.

I still have this squeak

Is seems to be the brake disc touching the pad as the wheel rotates and causes a high pitched squeak. Theres NO brake judder but could the brake disc be warped causing it to touch the pads and thus make the noise ??? The discs are Tarox groved and drilled and wasnt cheap, the pads are mintex 1144 if that helps.

The squeak does get worse when turning left and is silent when turning right, i guess when the weight transfers from side to side.

Any ideas cos i have thrown a good few hours and ££ at this problem now and cant find a cure for it
