Brakes

If you still want new brakes, I reccommend the Planet X cnc ones.

Bit fiddly but stopping power is excellent.

Try Fibrax lots of stuff to make your brakes better!

When was the last time you had the bike serviced or replaced the pads?

I would check if your pads aren't glazed over (has happened on my OEM Shimano and Swisstop pads). It's why I moved to Kool-Stop on all my bikes.

But bad brakes can come from more than simply the pads:

The braking surface on the wheel might have dirt/oil/grease on it. You can solve it by wiping with some burning alcohol (am not sure the English word for this). Or, Mavic makes a wheel "eraser" for alu rims that has a light abrasive compound that thoroughly cleans the braking surface : http://www.chainreactioncycles.com/Models.aspx?ModelID=7126

If the bike is old and has never been serviced (i.e.: changing cables and the cable housings) then you might suffer from rusty brake cables, which make it harder to brake as it wears through the liner inside the brake cable housing.

You may also need to adjust the amount of pull you have to apply to the brake levers before they touch the braking surface. If the pads are worn, it will require more travel to touch the wheel, leaving a sensation of it not braking so well.

My understanding is that Reporto Corse is, pretty much, re-branded FSA, so they shouldn't be too shabby. Personal experience is that Ultegra calipers (appreciate that you probably want to stick with Campag?) are excellent and, given that the new groupset is launching right now, there are some great deals to be had

Wipe the rims and pads with a bit of degreaser and then rinse them off. Makes mine really grabby for 5-10 miles.

There are some rims though that just don't stop well so it could possibly be the bike rather than your weedy hands .

What are you using to clean the bike? Could there be residue from that impending braking performance?

I've Athena brakes on my Infinito and they are sharp what rims tyres you running
