Hi all. Running Ksport 8 pots and just had new discs and pads.

When travelling below say 20mph there is a knocking coming from front off side.
Once past 20mph there is no noise and braking is perfect.

Noise gets faster as speed increases and then goes away.

If I apply brake when I can hear the noise, it goes away.

Any help or advice greatly appreciated.

 

Maybe "pad chatter" - when the pads move slightly (a couple of mm) in the calipers - it's the vibration of the engine and movement that makes them jump.
Hope it helps.

^^ Came here to say a similar thing, I often get it when i reverse into the driveway, and then first time i pull away again. Took it to a garage and they diagnosed it as that!
