yes you only need to bed them the first tie you put them on to bond the new pad in (this is from a former indycar driver). thats why race teams usually bed a batch of pads in during test sessions.

you sure you didnt have a rock stuck between the pad and rotor?

vibration comes from deposits on your pad or rotor
