You’re assuming they haven’t. If that were the case they’d squeal from off. As I said, they brakes need to get up to temp before it starts hence questioning the material compound.

Guys, I have recently replaced the pads and discs on the Disco5 twice within 6 months. Most recently 2 days ago. The issue is that when the brakes get up to temp they squeal like a stuck pig. The garage that fitted them are JLR specialists...
