Hi all,
I have had a set of EBC discs and yellow stuff pads replaced on my Jaguar XFR-S with the help of ChrisSB.
When they were removed, we found a very strange wear pattern on the inner face of the disc where it seems the outer edge of the disc has worn less than the rest of the disc and the pad has seen more wear at the top than the rest of the pad. The outer face of the discs and pads have worn uniformly. This is the same across both left and right sides. I have attached pictures of it too.
I emailed EBC, they wanted the discs and pads back to investigate but I’ve binned them (appropriately). They then replied and said,
“If the car is totally standard, I would recommend you have your front suspension geometry checked, we manufacture our discs to OEM dimensions, so unless you have a non-standard braking setup, we can pretty confidently rule out that this is a product issue.
It looks as though something isn't quite right, which is causing extra force to be placed on your uprights/discs/pads, causing this uneven wear.”
I didn’t think a geo would affect how the braking system works? The OEM discs and pads had 33k on them and wore properly as expected. My first set of EBC discs and pads only lasted 24k miles. That’s reasonable enough for pads but I feel that’s a very fast wear rate for the discs?
Wear pattern wise, I’ve never seen anything like it. Does anyone have any ideas as to what may have caused it?
