Hi,
Well i had Tektros on and they are fantastic brakes, certainly powerfull enough, even more so with Kevlar pads. But there was no modulation which is why i got rid of them.
I’ve just got some 2012 xt’s. And they are out of this world. Powerfull never fade, and wicked modulation so you can have as little or as much as you want.
But for your brakes, Rob Jackson is correct. But not only do you need to bed them in, you need to resurface the pads. So get some fine grit sand paper, and place it on a flat surface. Then simply lightly rub the pads on them in a circular motion. This will resurface them.
Then bed them in. If your still not happy, Re bleed your brakes.
