I now have an idea of what I need to do to get the car to stop when I want it to, and not when a truck forces me to!

As I thought I could do a cheeky little upgrade while I'm dicking about with the brakes, I was looking around for some braided lines and found these..

Are these bad boys any good, or should I steer well clear and get them elsewhere?
Also, what sort of price should I be looking at? They vary wildly!
Thanks again
Doug
