Interesting what you all make of this. I'm a heavy brake user, a Police style Advanced Driver since the 1980s. With exception of driving on snow, or when descending a hill, the engine gearbox and clutch play no significant part in slowing the car. All deceleration is via the brakes. The approach to bends is different, an Advanced Driver brakes to a speed suitable for the bend, selects the correct gear and drives in that gear before steering. This is the Police bit, out of the bend an Advanced Driver drives with deliberation and gets up to the speed limit purposefully. More speed to lose at the next bend. Admittedly anticipation, observation and maintaining a good distance stops all of the minor speed adjusting other drivers engage in. On balance though an Advanced Driver is heavy on brakes, lite on clutch and gearbox.
I don't think this is the cause of mt A2 brake issues. I think they are fit for purpose and are a similar design to brakes on other cars that I have owned and have had no problems with. I think the problem is the way I use the A2. It is used intensely for short periods then parked it outside for long periods. I think British weather is getting to my brakes. I'll report when I strip them down.
Edit, I forgot expect the unexpected. This means the Advanced Driver will be slightly slower around blind bends, across roundabouts, and in other situations where the unexpected can strike. Again more speed lost via the brakes.
