I must have hit a rock, It sounded like something f**ked something in the rear passenger wheel...
It squealed like a pig all the way down the ridge. when i Finally found a place to stop, I took the wheel off & break pads out and it was a horrid grinding noise. the dust plate thingy looked a little bent so gave it a whack to move it away from the break rotor. nope still grinding and crunching away.
decided to just limp it home so put pads back in & wheel back on...2 metres of grinding and it stopped..... FIXED!!!! I managed to drive all the way home home no issue as well as to and from work today with no issues.
thanks to Cieran for stopping with me & thank god we didn't get any rain while messing about.
this car and its weird disappearing issues... no idea.
