I know this has been discussed before but I could not find it when I searched, any way my car spends a lot of the time left parked on the drive with the hand brake on, the drive is on a slight incline and if its been left for a few days or more when I use it the handbrake is stuck on.
Obviously it’s worse if I have washed the car before but it is happening quite a lot, today when the handbrake was released and I finally managed to get it to release when I braked at slow speed there was a knocking noise from the driver’s side rear wheel, this cleared after a few miles of braking I cannot see any problems/damage in the brake/wheel area.
How can I prevent this? And what do we think the knocking might have been?

I probably am not using the car enough.
