Noticed when reversing after car has been left all day at work that there is a very slight (not a knock as such) but more of a click sound (only seems to be one click)coming from what I think is the rear of the car, is it likely to be anything to do with the handbrake shoes fully releasing as it were when reversing after handbrake has been on all day? funny thing is I haven't noticed it do this first thing in the morning after the car has been on driveway all night, so maybe it's an ambient temperature issue etc?
