BOSCH 40011057 QuietCast Premium Disc Brake Rotor - Compatible with Select Infiniti QX56; Nissan Armada, Titan; REAR - Single

Actually kind of disappointed in this purchase. Ordered 2 to do my front brakes. They came in two different size packages but I didn't think much of it. Pulled one out and it was covered in packing oil. Thought that was odd. Also had a machined surface instead of the "anodized type" surface that the box showed. Installed it and moved on to the passenger side.Pulled the second rotor out of the box and it looked completely different with the fully coated surface I expected from pictures. It was so different that I spent the next 10 minutes verifying part numbers matched on the box and the rotors themselves. I couldn't figure it out until I saw in small print that the driver's side (covered in packing oil) was "Made in China" and the nice finished passenger side was "Made in Italy".The difference in appearance does not give me warm fuzzies about the difference in manufacturing or metal alloy used. I guess time will tell. No more ordering rotors from somewhere that I can't see them first.

Bought from Amazon and installed with a set of Akebono ACT-787 ProACT ceramic pads on a 2012 Accord EXL. Works fine for 8 months and about 12k miles the steering wheel vibrates when braking at highway speed, two months later at 15k miles the shaking got worse to a point that driving the car was not pleasant and feel safe. I thought the rotor most likely warped.This was the first aftermarket rotors and pads I ever used for the past 30 years. The original rotors on the Accord warped at 35k I was disappointed as I usually replacing rotors at 90-100k at second pads replacement and that was the reason I tried Bosch, however it was even more disappointed they ONLY last for 15k. I need to replace the rotors and decided going back for Honda rotors and pads.Ordered the parts by mail received them yesterday and worked on it this morning. After removing the rotors, I was SHOCK to found both the rotors has a crack across the braking surface, one rotor cracked on the front and the other cracked on both front and rear surfaces. Last for only 15k and cracked? What an inferior quality and low grade material parts. I swear no more aftermarket parts!Today’s auto parts are not lasting as in the past no matter OEM or after aftermarket, all these greedy businessmen use inferior and low grade materials in their products and try every possible ways to squeeze every single penny for profits. What a shame!BTW the Akebone pad was performed pretty good but it was very dusty and made the wheels very dirty.

I read the great reviews when I bought these two years ago. I installed them and looked forward to a long-lasting high quality replacement part. Our van had over 100,000 miles on it and still had the original OEM Honda rotors when I put these on. A few months ago I started to get vibrations when braking and now the vibrations are so bad I don't feel safe, especially if I needed to stop suddenly at higher speeds. I am very disappointed in these rotors.UPDATE: I've waited three weeks for Bosch warranty support to call me back. You cannot talk to a live person. You have to leave a message with them. I will not be buying Bosch auto parts again.

Rotors warped very quickly. Call warranty support at Bosch. Left initially a voicemail without a call back. Called couple weeks later and talk to someone who again took my information for warranty people to be called back. Again, two weeks has passed and still not return phone calls. Stay away from those rotors as company doesn't stay behind its products.UPDATE: Called again, the customer service updated my initial ticket and of course two weeks have passed without a call back. Definitely stay away from Bosch products. I am done waiting and replacing rotors with a different brand as the car is un-drivable because of heavy shacking during braking.

Don't get me wrong, I installed Bosch QuietCast rotors on my '07 Civic along with QuietCast pads. Great purchase. However, Amazon's "check the fit" tool is notoriously inaccurate. The thing is, I went to Bosch's website to confirm the model # before coming to Amazon to order. I ordered these particular rotors for my '13 CR-V that had the OE rotors machined down to reduce noise. The Bosch rotors DID NOT fit. Took everything apart. Put the rotors on. I assumed they were a little thicker because the OE rotors had been machined. Started to drive the car and there was a TERRIBLE scratching noise. Took the car apart again to find these rotors are too thick for the car. The caliper bracket was scraping the out facing side of the rotor. I put the old rotors on with new QuietCast pads, and everything is ok. I'm going to try and return these rotors, but am unsure if Amazon will accept the damaged product back. If not, I will contact Bosch directly. Again, not one problem with my '07 civic. The Bosch QuietCast product is excellent. Don't let this discourage you from buying the product, but ensure everything is exactly right before install.UPDATE:I was able to return the now defective rotors to Amazon for a full refund. The Amazon team was very helpful.

I’m driving a 2006 Mazda 3 2.3. Installed Bosch pads for all corners, but I used Centric rotors in the front and Bosch rotors in the back (I was planning to test their qualities in real life). After driving the car over 18,000 miles around Columbus, OH, I have to say Bosch rotors suck!! The first two picture are the rear axle rotors and pads, the third picture is the front axle. Somehow, Bosch managed to make their own pads to eat their rotors that much. And that’s the rear axle, which has less braking force than the front one. Their coating didn’t prevent the rotor from rust at all. On the other hand, the Centric rotors have no rust, their surfaces are still smooth. And they are cheaper! BTW, I also installed Bosch alternator on my Mazda 3, and its bearing went bad after 9 months. I guess their “premium quality” is a joke...

I installed these rotors with the Bosch application for pads (Bosch BC1044 QuietCast Brake Pad Set) for my car (a Mazda 3 with the 2.0L non-skyactive engine). The braking performance is top notch. At least as good as OE, if not better. Dust and wear rate better than most aftermarket stuff like Certified, Wagner, Monroe, etc). However, the one and only issue I have is, often when cold and/or wet, and the car has sat for at least a few hours (over night), upon first brake application, particularly a light brake application, there is a bit of squeal. This goes away after the first brake application or two, but it is quite predictable based on the conditions described. And yes high-temp anti-squeal brake lube supplied with the pad kit was applied to the back of the pads.

The rustproof coating really seems to make a difference. I feel that these will outlast many other non coated rotors, as this will prevent corossion around the vents of the rotor. My previous non coated rotors ended up being badly rusted at this location and that contributed to shorten the life of the rotors and, of course, the pads aswell. I paired them with Bosch Quiestcast pads (please, dont buy cheap pads with premium rotors!). It works flawlessly. Smooth and efficient. Now my car feel safer and more predictable. Good fit for Honda Civic 98 (front). You always get your money's worth with Bosch. They never dissapoint and always meet expectations.

These rotors fit my 2014 Mazda CX5 perfectly and are very quiet. Unlike the originals on the car, these Bosch rotors are coated and it looks like they will not rust at the hubs like the originals. They are indeed very quiet - no squealing or grinding. I installed Bosch pads at the same time. I'm quite happy with these.

Its Bosch. It's great quality. Its priced excellent.Ok, this is an edit. I had my mechanic put these on last May, 2020. They have 20,000 kil. This is only March 2021. I just went to a Canadian Tire shop to have new summer tires put on. They said that my brakes need replacing...yes, these ones. I called my mechanic and will have him look at them in a couple of weeks. I will get back and update. Neither scenario will be good. Either the brakes are worn out, which I think and hope not. Or, Canadian Tire store is trying to drum up business!!! Stay tuned...

Your browser does not support HTML5 video.  Seem to be really good quality rotors! Feel identical to OEM (Nissan) rotors. Dont forget to swap the e-brake plug from the old rotors. Preform proper break in procedure. I used Akebono brake pads with this rotor and seems to be the perfect marriage. No noise nice pedal response. Will update later in the summer to see how heat will effect performance.
