My problem is not claiming that Lewis has some kind of brake issue. My problem is claims like if it wasn't for said brake issue, Hamilton would be braking 10 times or whatever better than everyone else because zomg he is such a braking god. That is ridiculous.
And I am specifically referring to that quote by Mark Hughes. What he described as some kind of special skill Hamilton uses is basically trail-braking. His claim that Hamilton somehow brakes much harder and later than everyone else is laughable.
It's always the same story. Like, Hamilton would be 1 sec faster than anyone else but the tyres are holding him back...now the brakes are holding him back. It's sad. Have you considered that maybe he just isn't that great?
And every time people bring up GP2, aka amateur hour, you just have to laugh.
I fully agree with your sentiment i.e claims of Hamilton braking 10 times or whatever better zomg braking god. Except that I don't specially see such claims, rather that this might be making the tenth or two difference to his current times.
I also agree that at F1 level, the skill that Mark Hughes describes about driving a downforce car and tapering off braking force with reducing downforce and judging it just right, whilst impressive at F3 level is par for course at GP2 and F1 level.
However what Mark Hughes describes is not actually trail braking, which you seem to have confused. Trail braking is carrying the brakes into the corner and even approaching the apex i.e combining steering input with braking, which actually goes against basic theory of getting all the braking done in a straight line before starting to turn in. It's difficult to do and risky. Yes F1 drivers do it all the time, but even amongst them there is a difference between the levels they can combine braking and steering input. Trail braking causes the rear to go very light and can easily snap into oversteer. Drivers that aren't comfortable with an unstable rear and confident in their ability to feel and catch it won't be able to do it as well as those who are very comfortable with oversteer under braking.
I think Hughes claim that Lewis brakes later than most is reasonably accurate. He tends to do very, very well on the hard braking tracks such as Canada where he tends to find chunks of time compared to his team mates generally being anywhere from half a second to 1 second a lap quicker, even almost half a second quicker than Alonso in 2007. The coming race in Canada will be a good indicator, because if he's comfortable with the brakes and car then he's going to be very quick - it's quite simply his specialty track. If Nico is quicker in quali there, that would be pretty telling really.
I still don't see it the way you do though - as it being some sort of excuse for him. It quite simply isn't. It's his responsibility to work with his engineers and find a solution. That is afterall one of the reasons he moved to Merc, for the new challenge and growth.
