Thumbs down BA front caliper design fault?

After three track sessions in the XR6Turbo we have come to the conclusion that there is a serious design fault in the calliper design under serious braking. We have done three lots of 200-300 km testing and at the end of each session the leading edge of the inner and outer brake pads are only a 1/4 worn but the rear of the pads are worn to the metal(like a wedge).It seems that the front of the pads are binding and digging into the pad support bracket when they are worked very hard. We are now going to run some ducting from the spotlight holes in order to cool the brakes.
On a good note the discs themselves are proving to be almost bulletproof as we are yet to change or machine them and have not even shown any signs of shuddering like the AU's and EF's

there was an article in the paper in sydney like 2 weeks ago about how the highway patrol have picked up a couple of XR6T cars, first as a stand in waiting for the XR8, but are so happy with them they are looking at getting more as a permanent basis. they did however say that the brakes, although good, did not stand up to the performance tests they carried out on them and had to upgrade them to the performance package too

whats the main differences between the BA and AU brakes??

Depends what you want in a car doesn't it. People who buy the XR6 don't want to pay $50k which would allow Ford to put on Brembos or whatever.

For the record, tapered pad wear is normal for standard type calipers. It's only when you get to four piston or more calipers that the piston sizes can be varied to provide the even wear across the entire pad.

In my VL Turbo Commodore racing days, we cut out extra thick backing plates from top quality steel and had our own pads made. The thicker backing plates, along with an added heat barrier material, provided more even pad wear with the single piston sliding calipers.
