went to go to work this morning and as i released the handbrake there was no tension on the cable and the rear brakes had frozen on, even moving the car backwards and forwards did release them and i tried lifting the handbrake up and down and that still didn't release them.
This has never happened before is there anything i can do to stop it happening in the future.
The only thing i thought of is leave the handbrake off but in leave it in gear.
