Evening

every now and again, when just pottering, normally in 4th/5th at low speeds, there is an abrupt jerk/hiccup, almost like hitting a kerb, its not a gradual thing, any body else experience this??

FYI, the owner before me has fitted front pads, and on the drivers side, the retaining spring for the pad is missing, the passenger side is not fitted correctly, would this abrupt jerk be the pads resitting in the correct position...???

as i think it happens after a period of braking.....
