What is the general feeling about the Zimmerman (ECS) cadmium plated rotors?

Black Sunshine · 01-02-2006, 11:35 AM

I've had them on my A4, now have them on the S4 and am not sure I really like them. I can't seem to get the brakes as firm as I would like, even in comparison to the 01.5 1.8T we have, those brakes stock feel firmer than my S4s.

Any thoughts?

I did two thourough bleeds, with ABS pump cycling. I have new pads, new rotors, plenty of bedding done... curses!

not sure whether they were in reference to the Zimmerman Cadium ones or not.

I have ECS slotted/drilled rotors and I need to bed the pads every few months. They are the PBR/Axxiss Metalmaster pads. There is vibration in rotors under light pedal pressure. Then a good pad bedding session pretty much sets the rotors back nicely and I'm OK for another few months. I have never had to bed like this with any other rotor/pad combination and I have run these pads on other rotors before.

the brakes simply can't take the abuse at the track.

I used slotted rotors, SS lines, Motul fluid, track pads, and I still was able to get them to fail.

if you never see the track, stock brakes are plenty suitable.

and friction wears the rotors away.

Like I said I just drove my parent's 1.8T Avant and those brakes feel so much more positive than the ones on my S4.

I am running bobcat brakes FYI, and am thinking I want a more assertive pad. I also run Motul RBF600 fluid.

Guess I could get SS lines, but I'm not sure how much those help... I had a leukwarm experience with my A4, so.

SS lines will help a little, but your brakes should be OK.

I used slotted rotors, SS lines, Motul fluid, track pads, and I still was able to get them to fail. if you never see the track, stock brakes are plenty suitable. __________________

After all, the brakes work on the principal of friction and friction wears the rotors away. __________________ "And Caesar's ghost, roaming about in search of revenge, with hate at his side still hot from hell,will in these boundries with a ruler's voice cry 'HAVOC' and let slip the dogs of war.
