i have been using the standard oem pads and discs from benz on my e250 with sports pack ( vented and cross drilled ) but was thinking of switching to ATE ceramic pads ..mainly because of the brake dust from standard brake pads .. i have heard the cermamics last longer .. anyone switched ?
cheers
 
hi m8ty was that supposed to link to an article ? it just takes you to a shop?
 
http://www.autoanything.com/brakes/the-best-brake-pads-ceramic-or-metallic.aspxA common question many drivers have when it comes time for new brakes is, “What’s the difference between ceramic vs. metallic brake pads?” While they both serve the same function, the short answer is “a lot.” For the longer answer, read on…

First and foremost, braking is a tradeoff. A brake pad that works fine on the street isn’t suitable on the racetrack, just like a dedicated race pad doesn’t function adequately on the street. There will never be one “ideal” brake pad for every type of vehicle or every type of driver in every situation. Driving style, personal preferences and usage requirements of your particular vehicle are undoubtedly different from one person to the next. There really is no perfect answer, so here we discuss the pros and cons of different types of brake pads so you can make an informed decision about which kind is right for you.
The Evolution of Brake Pads

Let’s start with a brief history of the brake pad. When disc brakes started to gain mainstream popularity in the 1950s and 60s, asbestos was the preferred material for brake pad construction due to its heat resistance and durability. It was also relatively inexpensive compared to other materials at the time. However, as the environmental and health repercussions of asbestos became known, these brake pads quickly fell out of favor and manufacturers were left searching for a new, safer and more effective way of curtailing momentum.

Organic Brake Pads

Organic brake pads (also known as NAO, or “non-asbestos organic”) were developed as an alternative to asbestos pads, composed of various fibers mixed with binding resins to hold them together. Some common materials used in organic brake pads include glass, fiber, rubber, carbon and Kevlar. The materials and tools used to manufacture organic brake pads are still the least expensive today, which is why the majority (roughly 70%) of new cars sold in the US still come with them from the factory.
Pros:


  • Soft, quiet, easy on brake rotors
  • Don’t require much heat to generate good friction
  • Produce less dust than metallic pads
  • Low manufacturing cost
  • Suitable for normal driving/commuting across many environments
  • Perfect for every day vehicles and drivers
Cons:


  • Only operate well within a relatively limited temperature range
  • Wear out quickly compared to other types of brake pads
  • High compressibility – can cause “mushy” brake pedal feel
  • Will quickly lose their coefficient of friction when overheated
  • Not at all suitable for performance driving

Semi-Metallic Brake Pads

As the name implies, semi-metallic pads contain anywhere from 30-65% metal by weight, typically consisting of steel, iron, copper, etc. combined with friction modifiers and fillers, as well as a graphite lubricant. Semi-metallic brake pads are arguably the most versatile style available, with the slight compromise being more noise and dust. They are also longer lasting and more durable, and their metallic composition can help draw heat away from the rotor and aid in more efficient brake cooling.
Pros:


  • Dramatically increased braking performance over organic pads
  • Have a much higher thermal threshold due to metallic content
  • Still provide good cold bite
  • Have a much wider operating range (temperature)
  • Low compressibility – will provide a firmer brake pedal feel
  • Much more resistant to brake fade than organic pads
  • Numerous compounds available – suitable for anything from daily street driving to extreme track use
Cons:


  • Tend to be noisier than organic or ceramic pads
  • Produce more brake dust
  • More abrasive than other types of pads – will wear brake rotors more quickly
  • More expensive than organic pads (but generally cheaper than ceramic)
  • Require careful and proper bedding-in for best performance

Ceramic Brake Pads

The comparative new kid on the block is the ceramic brake pad. Ceramic pads are composed of a dense ceramic material (like pottery fired in a kiln) with embedded copper fibers. In use since the 1980s, ceramic pads were developed as an alternative replacement for organic and semi-metallic brake pads because at the time these types produced too much noise and dust. Ceramic pads are also generally easier on rotors than semi-metallic pads.
Pros:


  • Quieter than semi-metallic pads – emit noises that are above the range of human hearing
  • Produce finer, lighter-colored brake dust which does not stick to wheels
  • Longer lifespan than organic or semi-metallic
  • Stable under a wide range of temperatures for consistent performance
Cons:


  • Typically the most-expensive type of brake pad
  • Do not produce as much cold bite as semi-metallic pads – may not be ideal in extremely cold climates
  • Do not absorb heat as well as semi-metallic pads which can increase brake system temperatures
  • Good all-around braking characteristics but were never designed as heavy duty/racing brake pads
Braking is a Compromise

Back to the question at hand - semi-metallic vs. ceramic brake pads. As said before, there is no single brake pad that can reign supreme in every single situation. If you want clean, quiet stops, you’ll pay for it in braking performance. If you want massive amounts of brake bite under extreme temperatures, you’ll be cleaning your wheels every few days. That’s just the way it works in the world of brakes. Ceramic pads offer quieter stops, cleaner wheels, and generally longer pad life due to their harder composition. The downsides include less cold bite, rendering them less effective in cold weather or before the brakes are up to temperature. In addition, they typically have a lower coefficient of friction than their semi-metallic counterparts (the higher the coefficient of friction, the better a brake pad will stop your vehicle). Ceramic pads were never designed to be extreme performance or racing brake pads. The ceramic material is also a less-effective heat sink than their metallic equivalents - instead they act almost like an insulator. The less heat the pad is able to absorb, the more the heat is retained in the brake rotor and surrounding components, which can lead to increased temperatures of the entire brake system.
Semi-metallic pads, on the other hand, while they do produce more noise and dust, are arguably the more versatile of the two. They are more effective over a wider range of temperatures and have a much higher thermal threshold. They provide better cold bite than ceramic pads and maintain much more consistent friction characteristics throughout their operating range. If you plan on driving your car in anger on a racetrack (or even a spirited mountain run), semi-metallic pads are the clear choice. But for casual city or highway driving, commuting, or chauffeuring the kids around town, ceramic or organic pads offer ample stopping power with the added benefits of quietness, cleaner wheels, and longer lifespan.
 
Iv just fitted EBC REDSTUFF on my E280 and all I can say is Wow what a difference,much sharper braking and virtually no brake dust anymore. They are not cheap at £80 a set as mine are brembo sports Calipers but well worth it image-53174843.jpg
 
i just went on to ATE website and looked through it.. looks like they dont recommend that you use the ceramic pads with perforated discs ( i think they way they work they need a flat surface for best performance ) mines have the vented perforated sports pack discs on them .. so a toss up with MB orginal or Pagid from eurocarparts

''Can I also use ATE Ceramic brake pads with the PowerDisc, or with perforated brake discs?
Yes, this is technically possible. The braking performance of this combination remains as good as with an ATE original or an OE brake pad. The way the two components work together, however, can result in an increase in braking noise. ATE Ceramic brake pads have been developed for the comfortable driver. Basically speaking, we recommend that ATE Ceramic brake pads are only used in combination with "normal", i.e. smooth, brake discs.''

I have used ATE ceramic pads with perforated discs for about half the life of my 32000 mile C350 with no problem. Original discs are still fine and pads dont appear to wear much despite some quick motoring. I expected to have some problems with cold braking but I haven't seen any difference in bite at the start of a journey.

In use they have performed at least as well as the oem pads with no noise and virtually no dusting.
