wow everyone will take sometime to digest that over the weekend, i am sure the amount of pad area relates to the amount of friction.

You make the pad bigger. This works just as well if you make the pad thicker.

I thought you were going to leave it to Bambi and the MoT inspector to see how the problem got resolved? However, since you ask, I don't think Bambis problem is heat build up - certainly not in an MoT test station. I think either corrosion and pad deposits have reduced the effectiveness of the pad / disc (hence my comment about giving it a thrash to see if it improves) or the caliper / piston is sticking.

"I think either corrosion and pad deposits have reduced the effectiveness of the pad / disc"

That's what I think, as a stated much earlier, but I put it down to wear of disc/pad.

There's an experiment that could be done to prove/disprove the theory of "friction has nothing to do with area"
There's a few things that would be needed.
1, need a test car (not mine thanks)
2, two sets of pads, one normal, one with 50% of brake lining removed
3, long road and brick wall
4, someone to drive, I'll put my hand up and test the pads with 100% of brake linings, anyone fancy testing the 50% ones?
