BMW 650 Rotor replacement

I have new pads but the brakes still squeek. I brought the car in the people there said I need new rotors...car has 65k on it. They qouted me about 300.00 per rotor place 80p/hour for labor. Found Zimmerman rotors online for about 100.00 a piece and thinking of putting them in myself. I never take the car to the track or need "high-performance" brakes.
Just wondering ig it as easy as removing wheel, caliper, rotor and then replacing said parts. (any lubing or adjusting needed??)
Thanks in Advance.

    Thanks to both of you. Ya the guys at the "free barke inspection" place said that the disks are "glazed." They said they could resurface them but said "if you can afford this car you better be able to afford the brake job." So, they werent to helpful or honest in my opinion. They said if you can feel a lip around the edge of the disks that I should replace them. (there definitaly is a small lip) But this is a summer car and I dont want to spent 1500 in new rotors. I am going to try the emory cloth....or would you reccommend taking it in and paying the 100-some bucks to have a mech. do it......or would a mech, just do the same thing with the emry cloth???

    FYI....I didnt put the pads in myself.

To eliminate noise, remove your rotors and bring them to any competent machine shop. providing they are not worn past specifications, you can have them re-surfaced. Ask that the shop dress them with a d/a sander while still turning on the lathe...this provides a non directional surface which prevents noise. (pads act like a phonograph needle and duplicate pattern on rotor, turning it to sound). There are also vibration plates on the back of the pads that help with noise...make sure they are in good shape. On a daily driver, you don't need thread locker on hardware, just make sure they are tightened well (locker can cause problems in future removal). Before re-using pads, (if not worn) place a piece of 60 grit sandpaper on a flat surface and do figure 8's with each pad to break pattern on surfaces...not too much, just enough to remove surface. If you don't need to spend big bucks on labor and rotors, try springing for ceramic pads...they aren't just for racemobiles...no black dust and work really nice!!!
good luck

    Thought that was a done deal long ago!!! If the old rotors are still within specs don't forget what I said about re-surfacing and putting a non-directional finish on them. then, if you need one for an emergency, you'll have a good one on hand!!!
    Good Luck!!

Hi there if you know how to replace the pads then you could do the disks ( rotors ) but you must make sure there is no rest or debris between the new disk and the hub all bolts on the caliper carrier should be thread locked. hope this helps
regards JR

Try this. first. take your car to thr carwash. wash them. do this every time yiu wash your car. debris can caus a squeek. if that dont work, you could have what is called glazing. this is caused from heat and worn pads. s lightly sand your rotors with emery cloth. both sides. if there is any damage to the rotors due to metel to metel you will experience viberation at high speeds.

Sounds like your pads are glazed. You probably need to replace the pads, and likely the rotors.

A light in the dashboard turns on today and I have no idea what is the symbol for? is like a circle with 3 rectangles in line on each side this is a BMW 318i, 1996


This is the brake wear indicator. When the brake pads get too thin, this sensor, which is mounted in the brake pad backing on the front left wheel and the rear right wheel, touches the rotor and wears through, grounding out the contacts and illuminating the light.
Once the light is lit, you will need to buy a new sensor as well as new brake pads. The sensor is not expensive.
First step is to examine the brake pads and determine if you need front pads or rear pads or both. Don't be surprised if you need new rotors as well as pads. Check for a significant lip at the outer edge of the rotor. If the pads have worn in the sides of the rotor more than about 1/16", you are due for rotors.
You cannot go wrong with BMW branded pads. They are safe and work great, but they are really dirty. If you want to try other brands, read the reviews. Some squeak and some fade.
I use Mexican made Brembo rotors. They work well but they rust quickly, so the brakes squeak a bit the first time you press them after washing the car or driving in the rain. More expensive rotors or BMW branded rotors don't rust so much, but they cost a lot more and don't necessarily last any longer.
After replacing the pads, turn the key to the On position and leave it on for about 90 seconds before starting the car to reset the brake pad warning light.

There is a funny squeeking noise on my back wheel


If it's a chirping noise, it could be a brake wear indicator. Pull the wheel off and check the brake pads and rotor for wear.

325 ci brake rotors have been replaced 4 times in 6 years


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.

Honda Odessey 2002 - Rotor brake


Yes, depending on the quality of the rotor, in extreme conditions it can rust out quicker. The brake pad graps the rotor, 'cleaning' it as it stops the vehicle. If the vehicle sits for a long period of time then it is more likely to accumulate rust. If a rotor gets out of balance, (this is what causes your vibration) it needs to be remachined. The rotor can only be machined so many times before it is too thin to use. The rear rotor must be thinner than the front rotor. Since this is a vital part of your brake system, it's money well spent to help insure your safety.
