The EBC should be available in Canada but I am not sure about the Rossini. EBCs are also cheaper & grooved but not fully drilled so there should be no chance of rotor cracking (although I did not have any trouble with the Rossini on this score several people on the web have mentioned cracking problems with fully drilled rotors)
Thanks a million Bill,
I'll do my best to get back in the posting mood. For me right now it's not easy.
Way back in the spring of 06 I complained of the rust whenever the B sat for awhile and asked that same question about the porportioning valve and was told that the rear pressure cannot be altered.
I've finally given up on removing anymore rust using the hill method. The grooves are deep enough that this method no longer works on my B.
Many of you have had your disks(rotors) changed on warranty and I've now made an appointment and we'll see what success I have at the dealer.
Wish me luck on this one!!
Cheers, Derek
The dealer has listened to my complaints and has installed new rear rotors as of Aug. 08 and with 32,000+ kms.
I was well off the warranty which ended in Dec. 07 but as a goodwill gesture they charged me $35.00 total to replace and install them ...but using the old pads(???).
I hope the grooves in the old pads wear smooth quickly or the rust will appear very quickly!!
The $35 represents 25% of the rotor costs and no labor. They also will replace all sliders(front and rear) at no charge at my next visit.( they have to order them in). I noticed excessive play in the front calipers(too much floating) and this caused a rattle on our Quebec roads.
I'm very pleased with what took place and will hopefully be free of rust for a long time.
The blue grease is the dealer installation and as you can see, they weren't shy.
I'm keeping my fingers crossed on the rear rotor rust.
I wonder how long before the blue turns to grey to match the dust???
Have to admit MB uses colourful products. Now if the calipers where painted to match
Bizarre (I would say borderline incompetent) of them to not change the pads with the rotors, especially considering the grooving that was on them beforehand. I might invest in a DIY set of new pads, Derek.
Yes it does go against all normal practices of changing discs & pads. ie it is normal to change to new pads with an existing disc but not visa versa and I've never heard of a main dealer changing rotors without changing pads before.
If you asked them to change the rotors as a chargeable job for you you can bet your life that they would insist that that they change the pads as well. "Oh you can't change rotors without changing pads Sir" you can almost hear them saying it now.
The thin grooves on the old pads should wear down in time but your braking will not be as good as it should be until they do as you are effectively braking on a much smaller pad area. I think I would change to a different make set of pads ie non M/B and see how they affect the wear on the new Discs (rotors) as you are now out of warranty.
If M/B are changing your sliders, however,it might be worth saying if you pay for the pads will they fit them in for you free of charge. (they would only do it with their own brand of pads of course)
I agree with you both!! Never heard of not changing the pads, that's why I mentioned it.
Keith, your dealer words were exactly my same thoughts"Oh..you can't change the rotors without changing the pads .. Sir"
It will be interesting to see if they have seated at the end of August when I'm back in.
If the rust shows and the rotors screw up they will know about it. I'm still on warranty but not on the extended brake wear warranty which ended at 2 years or 40,000 kms. Thanks for the feedback and the encouragement to go in the first place.

Find the Rolling Stone Song.

Bill,
I'm hoping that the blue grease spreads all over the rotors and really slows the rust down.
Cheers, Derek
My new disks are still shiny and rust free!!
The dealer has now installed new caliper supports on the 4 wheels at no charge.
If you find your brakes rattling at very low speed on rough roads, see your dealer and use Tips Document LI42.10-P-042196 as a reference.
They also painted all the calipers to match the new supports.
It didn't take more than 2 hours for the 4 supports and they probably just used a spray bomb to match the new (bluish) supports.
I'm extremely satisfied with them and the problem is gone... and hopefully for good. The heavy blue grease is also gone.
