Hi OC,
Hmm I looked in my Haynes, it didn't give any values, just explained what camber, caster and toe was.
I will look at the rust marks when I do the brake in couple of weeks time but I doubt I am going to adjust it as that may mess up the toe.
It was a computerised one with automatic lifts, I think it was called John Bean?
Normally for 2 wheel its £40 but they charged £35 cos I got 2 front tyres.
Regards
