What is your opinion of a working brake: good bite and good hold. Review:So put them on set them up then went riding the bite is not great but that is because of the booster i recon. The hold is amazing dont slip at all not even in the wet,and they dont make any noise Then i thought i would take the booster off to just see the difference..........amazing bite and very loud but not very good hold so the booster went back on
