This looks very interesting indeed, best of luck to you 
Does anybody fancy explaining to my simple self a couple of lines on inboard brakes and why they exist please? Always confused me...
Reduction in unsprung mass! Having the brakes attached to the diff, means less mass hanging out at the wheel end of the suspension, and so less mass for the spring/damper to have to control. As downsides, they are more difficult to cool and put braking torque (huge!) into the halfshafts, and hence, as modern vented discs have become lighter, they are largely irrelevant these days. (not to mention that heavier modern cars results in a more favourable unsprung/sprung ratio anyway)Does anybody fancy explaining to my simple self a couple of lines on inboard brakes and why they exist please?

That Jag rear suspension also uses the halfshaft as a lateral load bearing member................

Thanks very much! It makes so much sense too, I'm not a little embarrassed I didn't work it out for myself if I am honest.That Jag rear suspension also uses the halfshaft as a lateral load bearing member................

Nice summary That Jag rear suspension also uses the halfshaft as a lateral load bearing member................
