Question about 2003 BMW 325
My question is the following: Do 325 ci brake rotors need to be replaced, or can I just replace the brake pads? My service tech at BMW has advised me to replace the rear rotors twice (at 30,000 miles each time) and front rotors twice (at 30,000 miles each time). Why can't I just replace the pads as long as there is no wear on the rotors?
BMW rotors are not known for lasting very much more than 30-45k miles. When the brakes are inspected, they measure the pads using a special tool threw the outer brake pad. Min spec is 3mm. When the pads are replaced, they measure the thickness of the rotors. The rotor spec is stamped on the rotor. if they are under that spec, they recommend replacing them as well. Next time you bring it in for service, just ask them to measure the rotor thinkness, (its not a huge task, all they have to do is take the wheels off). But more often than not, the rotors wear just as fast as the pads.

Not true as far as BMW starting from some yar back. I happen to replace brakes on my cars and yes aI can do pads. BMW however requires front trotors replaced with every change of pads. This is BMW (manufacturer) recomendations and not a repair shop. This is new Euro norm and rotors are now made softer so match between pads and rotors are better and braking power is higher.
With older models you could replace only pads and perhaps just resurface old rotors.
