Brakes and rotors - is brand important?

Hey Guys,

I am glad that I found this forum - so much useful information!

I am about to replace front brakes and rotors. My car brakes great, no vibration or any other problems but my mechanic told me 10000 miles ago that my rotors are 5 mm wore out.

I got to amazon.com and found hundreds of options priced from $20 to 200. I am confused. Are rotors really so much different? Does cross drilling make them better? Are more expensive brake better?

Any finally - do I need semi-metalic or ceramic brakes?

Thank you

I bought my cross drilled rotors from Brakeworld (I think). Cross drilling helps them to cool a little quicker but unless you do really agressive braking I don't know whether it makes that much difference. I just liked the cross drilled better and was willing to spend a little bit more.

As far as pads go, I went with the Akebono Euro Ceramic pads. They do a good job of stopping me and there is NO dust.

Cross-drilling helps a lot when you have to make panic stop from 150 mph.
Rotors are mild steel. Mild steel is like clay. No matter from China or Germany - clay is clay.
It is pads that makes the big difference. If you are all for performance - go for OEM but they leave lot of dust.
Lot of members switched to Akebono pads that leave almost no dust, while difference in performance is not noticeable.

That's like asking Aibolit whether he preferred a cheaper parachute or a more expensive one when he fell on Barmaley.

I bought cheap rotors from China for my wife's Audi A6 and after about 5 months of 80% stop-n-go traffic they started to shudder. After it got worse I decided not to keep them on the car.

They were replaced with OEM Audi parts about a year ago and no problem yet.

My opinion is that it's really hard to tell the quality of something based just on price. Over-spending for a part certainly doesn't guarantee checkered flags and champagne.

Having said that, in general, my experience with cheap parts, like cheap tools, is that they end up causing more aggravation than they are worth.

For MB, I try to find OEM manufacturers so that at least there are some standards involved.

As a basic rule, I'd avoid amazon (as well as flea-bay) for parts unless you know exactly what you're doing. And based on your post, you don't (please don't take that the wrong way, but really, if you knew, you wouldn't ask, true?)

Best to stick with a good brand from a known vendor.

If you like things simple, buy the Zimmerman Z-coat rotors. The coating obviates the need for any particular bed-in procedure (just don't drive the brakes hard for a few hundred miles) and Zimmerman is an OE supplier for many European car makers.

If you don't mind brake dust, stick with OEM for the pads. They're usually cheaper and are designed to work great wet or dry, hot or cold. If you hate brake dust, Akebono are a popular choice, though I personally prefer Axxis Deluxe Plus.

Good luck.

Balo rotors and Akebono Euro pads, and you will be happy.

Balo is made in Germany and Akebono is made in USA.

Thank you for advice! I have bought the parts and ready to install them. I did change brakes several times in Cadillac DTS. Are there something notably different in the brake design on MB brakes on S500 4matic? Do I need any special tools?
Thank you.

What I plan on doing in the next 10,000 miles is the exact same as my 2007 Acura TL-S, source OEM pad and rotors, have the rotors cyrogenically treated and installed at the dealer.

What alot of people don't understand is, cryogenically treating the rotors will help extend the life of the rotors tremendously and eliminate the heat spots in the rotors. And, it is cheap to have them cryoed.
