BRAKE Pad, Rotors, & Calipers Discussion Thread (OEM, aftermarket, etc...)
Hawk has described the metallic carbon pads as "virtually noise free" and the ceramic pads as "Extremely quiet" with the only other difference between the two in the description being the dust issue. For me noise-free is first, dust second. Unless someone has the ceramic version and can vouch for them as being noise-free.

. A rule of thumb is one set back pads for every two sets front pads.
I can no longer go by VIN # on my Coupe, because my front brakes are AMG C32 4-piston, and my rear brakes are AMG CLK55 2-piston.

) I'm on my second set of rear pads and just put on new front pads a few days ago (original pads were on!), 70k miles. The fronts could have gone longer, probably about 80k miles before needed changing. My rears seem to wear out about every 30k.
on another note...anyone ever heard of Posi-Quiet?

Noise/squeal is created when the pads vibrate against the rotors, sort of like the same effect you get when you scrape chalk on a chalkboard. Of course you can lubricate the rotors/pads and eliminate noise but you won't stop well. The brakes pads float in the caliper, this is what allows them to squeal freely. So the most obvious thing to do is put a cushion between the pad and pistons. The easiest way is with antisqueal compound, sort of a rubbery glue type substance transfers the vibrations to a more solid object like the pistons and caliper piston brackets. Also, some brake pads, most noticebly the ceramics have stainless steel shims on the back of the pad that have a similar effect. The key with antisqueal compound is to put it exactly where it's needed (where it would touch metal, look at the old pad's backing plates where you can see the contact points as a reference) and let it dry before putting pads back in and make sure you don't scrape it off putting the pads in. Also you can take other precautions, 1) bevel the leading and trailing edge of pad (most new pads come this way, MB pads don't), this keeps the edge from catching and starting the vibration, 2) use emery cloth on the rotor in a circular pattern to create swirls in the metal so the pad catches quicker and misses the vibrtion point and allows the pad to mate to the rotor quicker, 3) clean everything before assembling, use a generous amount of brake caliper cleaner to make sure there's no dirt that may have gotten on the pads and rotors (brakes is a dirty job so this is not always easy but important).
Different pad materials seem to be more prone to squeal than others, don't know why but I wouldn't go with a pad known to be noisy. It doesn't really bother me but it bugs the heck out of my wife and then she bugs the heck out of me so the effect is the same, haha.
Thanks

your questions have been answered ad-nauseum !
I'd really like to know if the C320 Sport Coupe has the same brakes as the other w203 and find a supplier that can come up with front and rear creamics for my car.
