hi guys im getting a squeak sound when i reverse my friend said it sound like its comming from the back hubs. i have also noticed when you put the hand break on and go to drive forward it dont stop the car.

do you guys think the sound maybe worm hand break shoes?

also does anyone know the size of a x5 2001 rear wheel hub nut as i dont have a socket big enough so wll have to buy one but not sure what size socket i need.

thankyou
