You didn't even post which BMW you are working on. It is hard to know your level of mechanical competence, but from the way you asked the question the best thing is to take the car to a mechanic and pay them to do it.
If you insist on doing it yourself, buy the correct Bentley manual for your BMW.

BMW brakes are much like the disc brakes on any modern car. The biggest difference is the parking brakes are inside the rear disks.
It is easy to replace the brakes if you know what you are doing. Even on cars like BMW's and Nissan's, the brakes are easily replaced.
The cost to replace BMW brakes typically ranges from $300 to $1,500, depending on the model and whether you're replacing just the pads or both pads and rotors. Luxury models or performance brakes may incur higher costs due to premium parts and labor rates. Always check with a certified BMW mechanic for a precise estimate tailored to your specific vehicle.
Your brakes are getting low and you need to replace them.
To replace the brakes on a 2000 BMW Z3, start by lifting the car and removing the wheels. Then, remove the caliper bolts to take off the caliper and hang it securely without stressing the brake line. Replace the old brake pads with new ones, ensuring they are properly seated, and compress the caliper piston if necessary. Finally, reattach the caliper, replace the wheel, and repeat the process for the other side before lowering the car and testing the brakes.
Have to replace the brake sensors once you change the brakes and the computer will reset itself after a few minutes.
There is no need to spend the money if it doesn't need done. Typically your rotors last longer than your brakes do anyway, so you should be fine for a while.

This will greatly depend on what kind of brakes you have and which parts you are trying to replace. Do you have disc or drum brakes? If you have disc brakes, do you want to replace the calipers, pads, or rotors? If you have drum brakes, do you want to replace the drum, or the shoes?
