Front wheel knocking

[HiddenHOBO]

right ppl, i've started hearing a rubbing noise from my front left wheel area, had the car up, wheel off cleaned down all brake componants and its gone but now i have a knocking at low speeds, 10-20mph but if clutch is dipped or just out of gear its gone. I've seen a few post similar to this but all were at the rear and mine is the front.

Any help would be much appreciated.
