Brakes and pads

Is it true when you have the pads replaced, you have to have the sensors and rotors done as well on a 328? Thanx

IMHO the answer is maybe. OK, depends on number of miles on the brakes, and if the rotors (discs ) are vibrating (warped). As to sensors, if they have not activated (turned on the brake light) then they can be carefully removed from the pad (left front/right rear) and re-used. I have heard that the European rotors are thin and will not turn one time without being out of tolerance. I have a 1988 750 on which I just did pads, I did replace the front discs as they were warped (pulsing on braking), but the rear rotors were fine and not grooved so I resused them (brake sensors reused as well).

One owners thoughts.

Thanx Bear. Car is a 1996 with 60k. Only goes rount trip of 16 miles a day. No vibration. Just having brake light switch replaced now but the pads and rotors (front) $550?

I work at a dealership in philadelphia and you should always replace these rotors. They are much thinner than other manufactor's and were never designed to be cut. There is a minimum thickness spec on every rotor (being that you have bmw rotors on there now). your's is 20.4mm and yes I know that off the top of my head. The good news is that there are relatively inexpensive compared to other manufacters prices.
