I am running the AP Sprint kit and I have an issue with my brake pads that I am trying to figure out. These are XP10 front pads after 2 track days. (National Corvette Museum and Atlanta Motorsports Park)
Notice on the left pad the raised inner edge.
Here is a better look at it.
This is happening on the inner pad on both the driver and passenger sides. It looks to me like the pad is overhanging the inside edge of the rotor on that side. I think this is also contributing the the 'effing loudness of the brakes. They squeal like none-other. The instructor that was showing me the line at AMP had to ask if my brakes were ok. Coming into the pits everyone looks, cause there is no way you can ignore it. The only time they don't sound like a terminally injured helicopter is when I'm deep into the brake pedal on the track with them warmed all the way up. I will say that the braking performance has not been effected, and has been consistent and great every session.
I cant think of any way to adjust the position of the pad in the caliper to move it fully onto the rotor surface. Or did I install it wrong? It was pretty straightforward and nothing that I have seen talks about adjusting the caliper positioning, that would have been done by the bracket design and is the whole reason to by a pre-made kit.
The 1521 pads I use on the street look to be doing the same thing. But without the noise, and the raised part of the pad is not nearly as noticeable since there hasn't been as much wear on the street pads.
I overheated the pads and smeared them. AMP has 2 really hard braking zones that contributed, I had no smearing after NCM. But the smearing(and thus the heat) is located only on the outer end of the rotor, which would make me think the brake force isn't being distributed evenly.
Any thoughts on what is going on?
Pedal dance on most of the sessions, but not all.
