Hmm, it's going in to Glasgow Lexus, on Friday 13th.....Wish me luck guys..
Well, in the better weather we had yesteday I removed the back wheel, took a wire brush to all the rusty parts and cleaned out the brakes and the dustguard was not rotten, just a film of surface rust. Whatever I did I managed to fix the issue, may have been the dust guard rubbing the disc, or dirt or gravel trapped, I'll never know.
What I do know however it is a paifully slow process to raise the car with the supplied jack! If i had the space I would use a trolley jack for sure.
Hopefully that's my adventures over for another year. Ed.
