@ kirsconz, floating discs were designed to reduce knock-back. He's just tapping the brakes to make sure that he still has brake pressure.

[kirsconz]

these cars run a floating disk which causes the pads to move slightly away from the disks it gives them a better brake pedal they're not going wipe off bugger all speed at 200 plus k's that close to the corner

Ok. I haven't understood that part at 1:15 because I'm not a native speaker and the Australian accent isn't that easy ;-)

[blitziiili]

OK thanks :)

@blitziiili

kirsconze is sort of right...

It's basically done to check they have brake pressure.

They're taught to tap the brakes so if there's a problem they can try to wipe off speed early, instead of getting to the corner at 200km/h and realising they have low or no brakes.

@itsdamo1993 it brings heat to the brake pads

[kirsconz]

it brings the pads up to the disk

@kirsconz

No, like the commentator says at 1:15 it's a "confidence dab"

They're making sure the brake pedal is still there and has pressure.

[kirsconz]

the commentator is mark skafe 0.25 a confidence dab to bring the brake up

[blitziiili]

What is the sense of pushing the break for just a half of a second before breaking hard into the curve?
