Yup I am as stupid as I sound, I think I'm going to put myself up for a Darwin award.
Was bleeding the front brakes with my dads help yesterday and had both front wheels off the ground. When I put the wheels back on again I finger tightened the nuts. Brought the car back down then bled the slave cylinder. Packed up and assumed my dad tightened the wheels up, and he assumed I did.
Drove down M1, M25, M4 back to my place. Started hearing a noise while in traffic in south london. Pulled over and had a check but couldn't find anything. Drove slowly for a while and the noise was getting worse so decided to pull over when I got a chance but before I could wheel fell off and I slid about 3 metres on the front left disc!
So now I have a ruined disc, threads in some of the hub holes rounded and front wing bent!
I now need a new hub, can I replace just the hub or does the bearing need to be changed as well?
