I have fitted brand new Mavic Ksyrium Equipes and the brakes are now very poor on the front. Should you change brake pads when changing wheels or are there different/better brake pads available. (all adjusted ok and the bike is 3 weeks old so components as new.)

Many thanks for your help in advance.

i think we may need more to work on that they are poor. are they hitting the rim, are they stopping at all?

given its only 3 weeks old, there shouldnt be any problems. if the bike had done a good few hundred miles, you would expect the brakes to be worn and matched to some extent to the rim. that is, where the front or the rear of the pad hits the rim first dependant upon your set up. this shouldnt be the case after three weeks unless you have been really smashing in the miles.

Sorry the bike is 3 weeks old but I have upgraded the rims yesterday. The stopping power is not as powerful as it use to be as if the pads aren't gripping well enough, do new rims need time to bed in aswell?

Couple of things:
Could be the wheels had a protective finish on them which has contaminated the pads. - Wouldn't hurt to wash the rims with a detergent and or wipe with alcohol and do the same on the pads.
The rim/pad interface angles could now be different and it may take a while for the pads to 'bed in' fully, unless these were adjusted when the new wheels were fitted.

I think we've all been there at least once. It's a similar feeling to hitting the brakes in a car, and the pedal going to the floor.
