V50 : tyre wear and Brake Failure error

[12V50D3Auto]

Had the wheel alignment done less than 12 months ago was recently in getting the tyres inspected and have been told that they (by the same 3rd party garage that done the WA last time) need to be done again and two new front tyres required because uneven tyre wear on the front inner side so I'm thinking f.this must be something they didnt pickup, going through the posts relating to this issus here one poster pointed to the rear of front main suspension bushes. I used to be good at the spanners but haven't got the space or time now but could someone point me in the direction of these bushes or even better a part number as I don't want to go down the route of main stealer if I can avoid it. I've read poly bushes are better again and last longer again any opinion on them v much welcomed. Car has covered 345km.

I got a Brake Failure stop safely message twice in the past two weeks brakes are fine, fortunately on both occasions was able to pull in at the gate of someone's house on a backroad because the whole engine cut out and I was on a hill, if I am travelling on the motorway this would be a lot more serious and risky. I topped up the brake fluid but it happened again recently. Has anyone seen this before is it a quick fix again want to avoid the stealer.

After a bit of research the front rear bushes are these, from reading the threads on here I'm going to bite the bullet and bring it to the dealers to get a diagnostic check done on the CEM unit... .
