Yes. Braded hoses make a difference, but if you need to brake that hard you are probably going too fast!

The theory is that the hoses are stiffer and resist expansion more than the standard rubber hoses. This means that less pressure is wasted in the hose and so increases the pressure in the caliper. It's not a lot but I've noticed a difference on the SV.

As said above, I'd not bother unless the lines need replacing.
