F1 » Hamilton not focusing on Barcelona test row


Lewis Hamilton has said that his apparent lack of pace is of more concern to him than Mercedes' run-in with the FIA over tyre testing.

Richard.
A miracle could have happened but it would be a miracle if Merc could sort out race pace in 10 days considering this problem has plagued them for two years.
I live in hope as then we would have 4 competitive teams with Maclaren waiting in the wings.

Engineer.
Brembo calipers, how do they work differently from LH's previous setup?

Was that a faux paux or was it intentional?
If others were running with that tyre configuration surely it was intentional although I can't think why?

FI brakes are called carbon/carbon, that is both the disc and the pads are carbon but of different composition.
Mercedes uses as standard Brembo discs and pads plus Brembo callipers.
Mclaren uses as standard Carbone Industrie discs and pads plus Akebono callipers.

Lulu is totally bewildered at being consistently out-performed by Rosberg.
Rosberg has a better pace and tyre management then Lulu.
Lulu's aggressive style of driving includes his braking and his braking style generates a lot more heat which is transferred from wheel rim to the tyres that's one of the reasons why his tyres are gone sooner than the ones used by Rosberg.

A simple search for Brembo on the F1 site will reveal that JB has consistently used Brembo discs at McLaren whereas LH has experimented with both Brembo and CI, typically using CI. LH has continued to use CI at Merc, whereas NR is using Brembo.

So Lulu is using the same brake discs make as he was using at mclaren but now he is not happy with the brakes , can he or his supporters make up their mind as to what the hell is wrong with him? As otherwise I will have to ask Taipan!

You do understand that the discs are only one component of the braking system? You also have calipers, front/rear modulator, brake master cylinders and brake pedal linkage. Additionally you have the disc cooling configuration.

It is the interaction of all the system components that controls the feedback that the driver feels through the brake pedal and consequently how efficiently he can use it.

Drivers are reliant on having their particular feedback from the car to extract the maximum performance - remember when KR returned to F1 he had Lotus jumping through hoops to make a steering rack that provided him with the feel that he liked.

rob. I doubt very much if sunny is "twisting in the wind". he has more than enough experience to understand braking systems

lulu is a professional racing driver, and to think that he cannot adopt to a slight difference in braking feel, is just ludicrous. funny how other drivers can jump from team to team, and we never hear such palaver!. when button joined macca, did he moan about brakes? no, he just got on with the job that he was being paid to do!
maybe if lulu actually stayed with brembo discs, he might have better control? apart from that, he has a little control in the cockpit that can alter brake balance, so if the fronts are locking up, all he has to do s ratchet a few more degrees onto the front.
as regards the comment about kimi wanting a different rack, well there is nothing too strange about that. some drivers like a quicker rack than others, less arm crossing required. so to equate that to brakes, is a bit off!

"Quicker rack"???

Actually what was developed for KR was a non-linear rack. In the central position it requires a large steering wheel movement for small road wheel deflection. With more steering wheel rotation the resulting road wheel deflection increases faster and not in proportion to the amount the steering is rotated. This enables far more accurate steering control in fast corners and long straights. Quite an interesting mechanical implementation using eccentric gears.

Ferrari have a similar rack - watch Massa's steering wheel motion just prior to and during his crash in FP3.
