Hi All I drive a 2009 t27 Toyota Avensis saloon, I am having an issue with an alarm on the dash saying 'check parking breaking system' . Today I parked the car for 10 min and restarted the car this message appeared on the dash , I restarted the car and the alarm went , but after driving for another half hour the alarm came back when I parked and pressed the button to pull the handbrake .  The handbrake does seem to be working as in it is holding the car and releasing when I want it to , but
