Hard to describe this one. Normaly when brakeing you ride the pedal, and before you stop you ease off till coming to a complete hault. Sometimes however i find that i wil slow down and just before i come to a complete hault, it feels as if the pad is sticking then will suddenly release. It dosent happen all the time. I Have had new front discs and pads, however it was still doing this on the old set. Like i say dosent happen all the time. Im thinking maybe one of the front calipers is sticking?
