Re: To many front rotor changes
Make sure the caplipers are doing their job properly. if the calipers are not functioning properly that will cause uneven wear as well as a dragging, as in the pads are not coming off of the rotor and therefore rubbing while you're driving. also, check to see that you are getting a pad that will wear without so much rotor wear. they make pads that will absorb more wear so that you don't have to replace the rotors every time you have your brakes done. And if that doesn't work... no joke, change your braking habits. unfortunatly, to many people wait till they're at the stop sign or red light to apply the brakes instead of preparing for the known. my brakes have been on my truck (HEAVY) for 50,000 miles (hard use) and have only begun to squeak in the last 100 miles. Changed my brakes completely and my braking habits. good luck

Keep up with your oil changes every three months or 3,000 miles which ever comes first, also at same time have all fluid level check, fuel filter and air filter replace once a year, tune-ups every two years, have your brakes check once a year, unless then feel funny have them check right away, transmission if fluid and filter has not been change every 30,000 miles, I leave it alone or new fluid will damage transmission clutches and transmission will have to be overhaul within 30 to 60 days.
sounds like the pads have worn down, or there's debris between the pads & rotor. in my personal experience, the stock rotors from hyundai don't hold up very well. i replaced pads (front and rear) at around 45K miles, and had the stock rotors turned down. less than 1K miles later, the front rotors were already warped! there have been many complaints about hyundai's rotors, so i replaced mine with a set of raybestos rotors and also put ceramic pads up front. 20K miles later, they're still working great.
Rear brake shoes as fitted to drum brakes can typically last up to 60k miles with periodic adjustments, but you have rear disc brakes and the shoes will typically last half of that.
Also, modern brake pads no longer contain asbestos and are now made using harder metallic compounds; the direct result is that brake discs (US=rotors) are also considered to be consumable items as they are worn down by the harder pads. It's not unusual to have to replace front discs every other pad change and rear ones with every pad change; in both cases the mileage will typically be around 30k miles on most models.
Yes, he is trying to make money. Tell him to turn the rotors if they are within tolerance and call it a day. The service writer who told you that gets paid on all the parts you replace when in for service. BMW rotors are a pretty soft metal and that is what makes BMW the best stopping car in the world. They turn rotors daily in that shop so don't let them kid you. You should be able to turn the rotors a couple of times before they require replacement, which should be around 75k miles. If you run it hard though it will be under 50k miles. Please email me with any questions and please leave me a good rating. email@example.com
I had a 2008 rav4 and within the first 10,000 I noticed this problem. Had the pads changed at 12, 22, 30, all free of charge from the dealer. Had the rotors replaced as well twice, the issue came up again & since it was a lease I threatened to sue and I was released from my term fee free. If you are having the same issue post here we need to open a dialogue. I'm sure many people have just paid for repairs without thinking it's an issue on the vehicle. Toyota will deny it until it's a media issue....
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.
Did you buy factory pads or get cheap aftermarket pads? If aftermarket did you get the ceramic? The cheap aftermarket ones tend to squeal pretty bad. Like the last comment on here, you should have your rotors turned whenever you change the pads.
actually i just recently found this out (to my dismay) you can't use an air wrench to tighten jeep wheels with disk breaks. it took me about 200 dollars in warped rotors to figure that one out. it's a hassle, but they dont warp if you use a breaker bar.
