Break Noise!!
Hi evryone,
I had my front and rear brake pads and roters changed to Zimmerman Cross drilled and Porterfield pads R4-S .I also changed the 4 brake lines to a satinless steel lines.,and off course drain the fluied and bleed the system. After changing all that , I noticed my car makes clicking noise when I am coming to a stop .This never happend with stock rotors and pads . If i am describeing this noise, it would be like putting a sand paper on the rotors while turning the rotors! ,and that if you try hear it from inside of the car. However ,if i try to hear it from outside it is like putting a plastic card in the spokes of a bicycle. It is very quiet thugh. I started hearing the hoise only after putting all new rotors and pads. What could be the problem?. I have checked my car with a mechanic , and he told me this is normal , due to new pads and rotors!. I am not convinced thugh, esptially because i feel the padal now is spongy unlike before with stock it was firm .eventhugh, i changed all of that to new . Please help

From my experience with mercedes, stick to original rotors and pads. They are designed to work quietly and smoothly. However, no matter what you are doing always stick with original pads because they are soft and not prone to squeaking, although they give off a hell of a lot more dust.

And I was thinking of changing my rotors, pads and lines with a setup like this as well..NEVERMIND. I guess that's why stoptech/brembo,wilwood and etc are well worth the money if you are trying to upgrade your braking system.

Ok now,
I usualy drive my car in the highways , so i usually use very little breaking every now and then. But today , i drove my car inside the city , it looks like when the pads built some heat against the rotors the more sound likely to come. , and when the pads cool off , the sound is less !

So unless you get very soft pads with the Zimmermans don't waste your money! GO with Brembo or stick with dealer stock.

Stick with factory pads at least if you are going to switch to zimmerman. If you want to try a lil cheaper than go OE PAGID or OE TEXTAR to save a few bucks. Very similar pads to stock OEM.

Sent them back to where I got them from and they sent me a new set including new pads, SAME result! Only thing is this time if I looked at the face of the rotor I could see numbers of the drilled holes was scored badly on the leading edge, thus creating the whirring sounds and bad vibrations under heavy breaking (the rotors were warped again!). Each time I took care in "breaking" the rotors and pads in with no heavy breaking etc. for the first 200 miles etc. SO to cut a long story short I eventually bought a set of rotors and pads from the dealer. Now I have quiet breaking and LOTS of break dust but I do have excellent breaking!
