I doubt you would notice any difference in just 'normal' braking that is how brakes work.... my requirement is to maintain the braking performance in a very hilly environment, brakes getting used a lot, so getting rid of the heat and maintaining the balance is what I'm trying to achieve. From some of the posts it looks like some people have already done this, I was going to do it anyway, but the advice so far has saved me many hours of research, trial and development. This is great forum experience, so thanks for the assistance. As for the expense, I don't think it will be too much, the rear beam needed to be replaced anyway, new disk / calipers, fairly cheep, anyway, I'm a retired engineer, I love doing this sort of stuff, we didn't go to the moon 'cos it was cheep or easy, it was a challenge and a puzzle and I do it 'cos I want to...and to just get rid of those stupid self adjusters !!!
