Nah,it´s just how Vees on the back usually are,they are silent in 99%,they aren´t bitey either,but they hold better than maggie in 100%.It´s mostly about setup too,even cheap generic pads like onza etc can work oustandingly good if coupled with good lever and decent arms,clean and well grinded rim a pads hitting the rim perfectly flat.If they don´t hold,you did something wrong.Bite is something you have to deal with if yo want to run grind,only time my vee is really bitey(in fact more bitey than most maggies)is when my rim is almost smooth and with little tar,in that case they are also very loud,but hold isn´t perfect so I prefer excellent hold and silent brake.
