Hi, hope someone can help.
I did a trackday in my 2004 r53 CS, before hand I changed the pads and discs to upgraded Ebc red stuff and grooved and dimpled discs. The car was driven very hard on the day. Since then I have had serious shudder under braking felt through the steering wheel.
I have since replaced the pads for green stuff and had the discs polished using 80grit to get rid of material build up.
Today I polished and cleaned the hub face and inside disc again to make sure there was no run out.
After a test drive I can reveal it's a bit better but the wobble is still present.
Ebc are sending replacement discs on Wednesday.
I'm at a loss as to what else to do really. Discs don't warp before you say!
In summary;
New discs
New pads
Discs cleaned of material
Mounting surfaces polished for run out
Wheels rotated
Wheels balanced.
I'm tempted to go back to standard as there was less drama during braking anyway. These new ebc ones are so noisy and make a grinding noise.
