I have recently purchased some brakes from Brake Pads | Brake Rotors | Performance Rotors | Cross Drilled Rotors | Performance Brakes and I am having some issues. I would like to just share with my fellow crossfire buds the problems that I am having with this company so no one else has the same problems.

I have ordered some drilled slotted and zinc coated rotors and pads from this site and was told when they are sent out I would receive an email with the tracking number... I had the date of purchase marked in my calendar waiting to receive the number, but I never did. So, one morning I opened the front door to stub my toe on a box that was a complete surprise to see.... hmmm my brakes that I never knew were sent...

Wonderful a Saturday with nothing to do. So I figured I would in stall them. Well after having my car tore apart in the garage I fitted the first rotor screwed in the locking screw and gave the rotor a spin. I came to find the rotor was not made right and wobbled as it spun on the hub. I then stuck the other rotor on and it did the same. So I packed them back up and they are sitting boxed up in my garage as my old brake wear down to nothing.

Since then I have left two voice mails and two emails... Still no response.

Just wanted to give you guys a heads up so this doesn't happen to anyone else.

 

Thanks for the info, about to do new rotors myself.

Glad to see another younger Indiana person, especially with another black XF. What area are you in??

 

A couple of things to consider. The screw that holds the rotor on is only needed to keep the rotor in place with the lug holes lined up while the wheel is off. Since there is only one screw it is not meant to hold the rotor perfectly flat on the hub so some wobble should be expected. You can either bolt everything up and check for a pulsating feel in the pedal which means warpage or just take the rotors to a shop that turns rotors and have them checked. If there is a slight warp it may be able to be corrected by turning the rotors.

Another thing you may want to check is if they sent you two left rotors. Crossfire and SLK rotors have directional cooling vains. When the rotor is on the car, the cooling vains on top should sweep towards the rear of the car. I recently bought some very expensive Disc Italia rotors and was suprised that they only use left rotors for both sides. This means the right rotor cannot cool effectively like the left one. I am also getting squeal from the drilled/slotted rotors and am ready to ditch them for OEM rotors.

 

Yep, what he said!

 

I have disc Italia pads sitting at home and I am about to purchase their D/S rotors front and rear, I was unaware of the 2 left rotors issue, are these ones I should stay away from?? Also, is that squeal inherant to D/S rotors on these cars, b/c I have had them on other vehicles and never had any unusual brake noises. Thanks.

Sorry for the threadjack.

 

I was just frustrated that at the price I paid for Disc Italia I expected something better than the very low cost Ebay rotors, but they were identical in every way. I am not sure that those who have these rotors know that they have two left rotors. If I don't find a higher quality after market rotor, I am going back to OEM MB rotors.

 

Have you checked out the brembo rotors for the XF. Even more $$$$ than disk Italia and it would be an expensive experiment to see if you were getting a high end rotor (like we thought the disk Italia would be) or if you get the same **** with a brembo box around it....

So I am guessing you would not recommend me paying the extra money for the DIs, just get a reputable one off ebay or something?

 

This is what is on their web page when I just wnet to it!

If I buy a third set of new rotors, I am going to make sure they have directional curved cooling vanes and that there is a left and right side. I would have have in Brembo but since there is a left and right rotor, there should be two different part numbers. To me Disc Italia are just slickly marketed Chinese Ebay rotors that cost an extra $100 dollars. The Ebay rotors actually had a better coating on them and the disc Italia rusted right up. The OEM rotors are not a bad price and probably the best quality. Too bad the SRT/SLK32 rotors don't come drilled like most of the other AMG models do.

 

Thanks for some of the tips. As this is my first time at brakes on this car and it is really pretty simple. And even through the screw is just a setting screw the rotor was seriously warped way beyond even acceptability. So they still sit on my garage floor while I went to the local TireRack and purchased akebono pads and some power slot rotors. All of the parts just from looking a them seem better quality. Plus, not to mention the akebono pads came with brand new brake sensors and some brake lube. Lesson learned and serves them right for not being up any more. Just for reccord 2 emails and 2 voicemails and still no word in 2 weeks.... still counting.

 

I feel your furstrations! Please let me know if the power slots are directional and if you actually get a left and right rotor. I was very disappointed with the Disc Italia. If you have not don brakes before remember the lube goes on the back side of the pad where they contact the pistions and keep the fircition side very clean. Let me know if you run into any problems or questions.

 

Yes, the power slots are directional and they do have a clear markings as to which side they go on. The quality looks great but we will see when I match them up Friday. (still waiting on rear pads to get here from the Delaware warehouse)...(UPS just got here!). I will be scrubbing and coating the calipers (black) with some ceramic paint to keep them from rusting. Ill post pics.

 

hey latanaTX where didyou buy those disc italias? I am about to buy them from brakeworld .com, but stopped the purchase after seeing this post.

mmz timelord is using them for racing and his posted pics look directional.

thanks for any further info you have on this product. Herman

 

I got them from Brakeworld.com They do slot and drill them for a left and right but the issue is they are using two left rotors (blanks) to drill and slot. the Crossfire uses curved vane cooling vents which you cannot see in a picture. What you are looking at in the picture is machined slots and drilled holes. I wouldn't waste the money on Disc Italia as they are identical to the cheap Ebay rotors I bought. the ebay rotors actually had a better coating on them to prevent rust. I would reccomend you verify where the rotor blanks were cast (foundry) China is crap, USA, Japan, and Europe are good. I doubt Disk Italia are from Italy. they are exactly the same casting as my chinese rotors. No where in the Disc Italia box or paperwork did they say they acutally were made in Italy. The Power slots mentioned above would be a better choice if they are really right and left rotors. you can usually spot Chinese rotors becasue they don't take the time or expense to reproduce both left and right direcitonal rotors. I hope this is clear as I am not talking about the slots or drill holes.

 

hey thanks for the quick reply! the brembro @ 15% more are looking much better now. I wonder why no one has posted the same issues with these rotors before

 

I used to desgn and sell big brake kits to the Mini Cooper crowd. I know what to look for. I only bought the cheap rotors first because I wasn't sure everything would work. After I knew it would work, I went for the disc Italia and got a rotor that in my opinion wasn't as good as the cheap ones. Unless you are rich being first with something that is unproven mean you have to keep costs down. With the V8 Project I found a great deal on an almost zero miles CL500 engine. If this thing ever runs the next person will know that it can be done and just go get an AMG55 engine.

 

Gernerally, disc brakes have a High Spot on the disk that forces the brake pads apart after brake pedal pressure is released.

 

Here is more info for you guys. I bought a set of Power Disk slotted rotors for the Aero from BrakeWorld last year and they were left and right directional. They didnt list rear rotors and I had ordered Xbrake rears but when the rotors arrived, I had front and rear Power Disk slotted rotors. The rears were a new item. Oddly the rear rotors still dont show up on the Brakeworld site. The Power Disk rotors work very well and are quiet.

 

Good info. I have switched to OEM rotors that I bought at the MB dealer last week and everything is quiet now. Oddly, MB lists left and right rotors but the number is now the same. the parts guy said that the original rotors numbers have been replaced with a single number. So the new rotors are technically both left handed. I put them on the car and now everything is smooth and quiet. Any need some almost Disc Italia's or disc Chinaebay? They both squealed on my car. The disc Italia which everyone thinks are so great were not as good as the ebay rotors in my opinion. The ebay rotors had better zinc platting which helped prevent rust. the disc Italia rusted right up were the pads didn't contact them. Other than that they are identical. It is common prctice for companies to buy cheap rotors from china and then run them through the CNC machine for drilled and slotted, then zinc plate them and sells them as some great quality rotor. I would suggest that anyone buying after market rotors, find out where the foundry is. Chinease rotors are the worst quality, while Japan, USA and Europe make very good rotors.

 

I ordered SP Performance rotors and they should be here any day. I will let everyone know how they are as I have high expectations for them. They have a high quality finish on them and are slotted and drilled.
