Problem: OEM pads = break dust. Solution: Install EBC greenies.
Result = both front rotors scorched blue, brake fluid boiled turned black/green after 2000 miles.
Non-Benz mechanic topped off resevoir with DOT3 instead of DOT4 mixing the two. Did this cause the fluid to boil?
After about 400 miles on the greenies, still had break dust and from then on.
Now have new rotors and back to OEM pads with loads of dust.
What happened? I suspect installer had wrong pad part for my wheels. Then with the fluid mixture boiling, the master cyclinder was not able to open the pad off the rotor.
I don't know for sure...how does it sound? Any advice or answers on this? Thanks.then

I've heard some pretty harsh warnings about not using EBC pads due to excessive brake rotor wear. There are some good low-dust alternatives.

About a month ago (and 1000 miles) I installed a new set of wheels on my 1994 E320. The brake dust from the OEM pads on the old wheels was killing me. So, at the same time I installed PBR Deluxe pads on all 4 corners. I immediately went on a 300 mile trip and was totally surprised that I had NO brake dust. The PBR's feel ad perform like OE without any squeaking. I don't think I will ever use another brand pad. Good luck.

black brake fluid just sounds wrong to begin with!

Flush that out and put some ATE SL or ATE 200 or ATE BLUE brake fluid in there.

All brake pads make dust thats how they work. Mercedes brake pads (OE) textar, jurid, etc, they have a lot of graphite in them which makes the dust look very dark grey.

Other manufacturers make brake pads with less dust because the dust is a lighter color, you just dont see it as easily as OE pads.

For a disc to look blue I would think that it would have to get super hot, maybe a caliper was sticking, but not both, thats highly unlikely.

I am doing a group buy on porterfield pads, which are claimed to be rotor friendly, but with those rotors in that conditon you should get new rotors.

I just thought of something I bet that your master cylinder is stuck. If both fronts are glazed, then the front part of the master cylinder is probably locked up.

If thats the case, you should replace it.

I switched from OEM pads to PBR Deluxe pads on my 1991 300SL. Very little dust as compared to the OEM's and no noticable difference in braking performance or feel. No unusual wear on rotors in about 10000 miles. It is recommended that brake lines be flushed out every now and then. I can't explain what happened to you, but perhaps the calipers were somehow damaged when the pads were installed. TTT

I hate the brake dust and squeal problems--where do I get these PBR pads, how much do they cost, and do they have the wear sensor wire that plugs into the MB harness. If they don't, does the annoying light come on in the dash? (Mine currently has no warning lights on, would like to keep it that way!)

You need bigger brakes! Brembo, Stoptech, etc.

You can get them on this site. See the fastlane link above. You won't have a problem with them with regard to your sensors.

Guys: tell us more about the PBR Deluxe pads and the Porterfields. Please provide web sites. I still want to change to non-breakdust pads.

Brake pad info go to: www.epsparts.com/category/chassisnumbertable

Interesting, kind of turns me off the PBR Deluxe altogether.

I don't know -- it sounded pretty positive to me...

Go PBR and don't look back. I had them on my E320 and they were great. I've got the EBC greens on my wifes C230 and they have totalled the rotors. I will be installing the PBR's on her car next week!!
