Where can i learn to brake in corners...

[mr self destruct]

These guys teach advanced cornering course at Malory park that includes emergency braking at corner,

I am keen to try that at some point too

I did this a year ago and can't recommend it highly enough. Part of it was emergency stops at 60mph on a bend, which was complicated but effective. I need to go back again for a refresher!
