On a BMW 323i, do I always need to change the rotors when I change the break pads?

I was told by a mechanic on a BMW I always need to change the rotors when I need a break service, not like in other cars where I could only change the pads and thats it. Its this correct??On a BMW 323i, do I always need to change the rotors when I change the break pads?I have a BMW 325IC and you absolutly do not have to change the rotors with each brake pad change. now if they are warped {which you would know by a shake when you apply the brakes} you can have them machined{a process of grinding them to a perfect resurface}, unless they were machined before. Even then they can be checked and if they are with in spec {a certain thickness} they can be machined again. I also own a high performance sports car and the same is true.If at any time you do need to replace the rotors I recomend getting after market vented rotors, better braking, longer life and at almost the same price...hope this helpsOn a BMW 323i, do I always need to change the rotors when I change the break pads?
I really doubt it. Although I don't own a beemer, I do the maintenance myself on my jeep. I've change pads before and left the rotors. This was at 60k miles. When I got to 160k miles, I had to change those pads again along with the rotors. What I'm saying is that the rotors lasted about twice as long as the pads. The mechanic is trying to pad the bill. You can do it yourself, it's much much easier than you think.On a BMW 323i, do I always need to change the rotors when I change the break pads?NO, HE JUST WANTS YOUR MONEY.
I HAVE A SHOP AND THE DEALER RECOMMENDS CHANGING WITH EACH BREAK JOB BUT YOU CAN HAVE THE ROTORS SURFACED AT YOUR LOCAL PARTS HOUSE OR MACHINE SHOP . AND YOU WILL BE OKOn a BMW 323i, do I always need to change the rotors when I change the break pads?No you do not, you should change the rotors typically every year and a 1/2, depending on how much you drive it. on my 3 series i put on approx 6500 miles a yr, and change it then. it really depends on your driving habitsOn a BMW 323i, do I always need to change the rotors when I change the break pads?
I don't think the mechanic is leveling with you. Rotors get resurfaced until the thicknessfalls below the engineered spec. Even then they are still functional but a liability issue develops so shops won't turn them below the spec.
I would go and get a second opinion. Rotors are usually changed if the outer suface has become to thin to cut.The rotor has to be a certain thickness.Another reason rotors have to get changed if the rotor was gouged which you didn't say.In most cases you can get one cut(resurfacing) on the rotors.On a BMW 323i, do I always need to change the rotors when I change the break pads?
no. if you have a shake and your rotors are warped, you CANNOT have them turned. they are warped and no turning can straighten them out. There is however a minimum thickness recamended by BMW and it is usually stamped on the rotor somewhere. I've had a rotor snap on me. it breaks off the hub and free spins and you have no brakes on that particular wheel.
