And brokensmile209 if you want to keep your ride in good shape and last long try always to get OEM parts! But if getting autozone parts make you happy just go with then but is not the best option! Good luck

I mean, if you aren't doing track days or any type of real aggressive racing...are autozone pads that terrible?

Autozone parts are perfectly fine. You just have to pick and choose which ones to get from autozone. Brake pads are expendables. and i've always gotten my brake pads for all my cars from autozone. everyone i know picks up autozone brake pads. as for rotors. . . There just round pieces of steel. if your not shooting for performance or trying to see how fast you can decelerate from 100, you'll be alright.

All points kinda valid, with my major comment being that there are thousands of kinds of steel cataloged and produced for real reasons. It sure does make a difference.

Autozone pads will stop you fine, but when the world class Axxis Metal Masters are available from Turner Motorsports, why would you choose to save a few bucks? BMW's represent premium cars at the top of their category in the world. Why pursue this brand if you immediately start to cheap out?
What do you want your perception of the machine surrounding you when you blitz down the highway or deftly pilot your auto thru some mountain roads?
Or if trips to the drugstore are all you care about, choose a lessor and more affordable vehicle than one with double vanos twin overhead camshafts, etc, etc, etc!

Don't Honda's have twin overhead cams?


And I wouldn't call it 'cheaping out' if they still provide the same functionality as the OEM brad pads provide.

Bottom line is Advanced or Autozone pads, while not OEM, will still stop your car. While I would rather go with something OEM, I haven't seen any hard evidence to tell somebody to not go with an Advanced Autoparts solution.

We're also talking a 30,000-ish mile expense here. It takes a long time for brake pads to get to the minimum level. For that length in time, I would rather have quality pads than cheap ones from AutoZone, especially when I know that higher-quality, quieter and less-dusty pads could be purchased for not much more elsewhere.

Not disagreeing at all. Autozone pads are a solution....just not the optimal solution.

Guess you deleted the modifying 'vanos' before you read my words?

BMW three series six is an award winning design that has been acclaimed by automotive journalists over the past couple decades. Never saw them rave over the Honda twin cam.
And yes, I'd gladly ride in a Honda to the supermarket if my BMW was broken. But I'd rather have it working and experience something sublime. The designers did not achieve that by shopping at the lowest bidder.

Didn't delete anything. I was simply stating that DOHC's are not a defining feature. But now that you're down off your soap box we can get back to the topic that OP started this thread for.

That's a roundabout way of admitting you're wrong and apologizing.

nope...Hondas and other "low end" cars have DOHC. This is not a BMW exclusive feature.

Get to this soon. Dealer said 1500 miles after the warning light, but I think that they wanted me to buy rotors!
Micrometer's are so expensive aren't they? I was going to look into getting one since my pad sensor went off, but just decided to replace the rotors based on the lip created by the brake pads.

OP, as everyone has said, you can go with Autozone, but not recommended. I priced out pads(textar), rotors(Genuine BMW), and a sensor for my fronts for 200 dollars or so. Probably going to go with zimmerman or brembo to save 15 bucks, but haven't decided yet.

micrometers not expensive

Best to replace rotors with pads always.

Will do.

I was under the impression that you could get through two sets of pad on one set of rotors, no?

I got a 05 e46 sedan and i have brake sensors all around.. Could be just the model/year though.

You will need new pads, and you _might_ need new rotors. Rotors wear out, but depending on how agressively the brakes are used, it is common that rotors will last through two sets of pads. The light you had come on tells you that the brakes have worn to the point where service is required, but it does not indicate that the front brakes or the rear brakes are calling for your attention. You only know this by inspecting the brakes.

How far you can go from here on the brakes depends on how agressively you use the brakes. If you are the kind of driver that uses the gas right up to the moment that the brakes are required so you slam them on as hard as you can, then you should do your service this weekend -- tomorrow would be better. But if you notice that the next traffic light is going to be red when you get there so you take your foot off of the gas and then lightly apply the brake as needed to slow at a comfortable rate, then your brakes will be good for another thousand miles or so. One thing to keep in mind is that the brake pads are a heat sink that draws heat away from the rotors, and when the pads are thin -- yours are very thin, that's why the light came on -- then the heat sinking quality no longer exists, so the rotors will be getting hot. Also, you want to replace the pads before there is any metal-on-metal contact, else the rotors will be destroyed. It is possible that you can use the rotors on another set of pads, but if there is metal on metal contact, this possibility will be removed, and you will be guaranteed to have a higher parts cost.

Assuming typical wear, you should find that you need front pads replaced at about 50,000 miles (brake service can be rounded to 50,000 mile intervals, sometimes you get more, sometimes you get less.) Then the next brake service will be for front pads and rotors, and rear pads. The next will be front pads, the next will be pads and rotors on all four corners.

If the rotors are scored for any reason, then they need to be replaced because the metal is pretty thin, and they have a minimum thickness specification that does not allow them to be machined flat again and still be thick enough for an acceptable service life.

You will need to inspect your brakes, you have to remove a front and rear tire and physically look at the brake components, to see what you need. Normally you do not need to do anything with the brake calipers -- the large metal chunks that the pads fit into -- so you can look them over for signs of a leak and forget about them if there are no leaks. You need new pads and you will need a brake wear sensor. You may or may not need rotors. Assuming you need rotors, pads, and both sensors, you should expect a parts cost of about $300. You can spend more for performance parts, and you can spend less. Spending more is not a bad idea, spending less is a horrible idea. Normal and customary parts from the local autoparts store will run from about $250 to $350.

If you have not done brake work before, then DO NOT do this by yourself. Find a friend or co-worker that has a variety of tools -- the wider the variety, the better choice of co-worker or friend -- that can help you to learn how to do this. It is not a difficult job, but it is also not one that you should be doing by yourself the first time you do it.

Hmongs are farmers from Southeast Asia, right? Do not be offended, but I recall them to be either ethnic Vietnamese or Cambodian.
