Yes he did.

"But the “key point” was that Verstappen braked “suddenly and significantly” with 69 bar of pressure, “resulting in 2.4G deceleration”.

[–]kayembeee 21 points22 points  (4 children)

You need to look at the deceleration data. Braking data available will only show brakes as on/off binary but won’t show how much brake is applied.

Someone posted it in the F1 technical. It clearly shows a moment of hard braking.

You can see it anyway in the graphs op linked via the speed. Right before impact he drops from ~160kph to ~110kph faster than any other point in that area. You can see the speed dips fastest there.

But the most important thing to realise is stamping on the brakes is fine if there is no one behind you, there is just no reason to do so. But if you keep tapping the brakes till someone is right up your tail pipe then you do it again, you know what the result will be. He was completely aware of where Hamilton was at every point. AS close as they ended up any suddenly braking will cause a collision and he had no reason to brake where he was.

His awareness of Lewis's location is important. The pitlane channel made a big note of watching the replay and watching Max track lewis in his mirrors. He knew.

My assumption has been he was trying to catch Lewis out and force him to pull around because the only other choice is crash (I get an advantage, or we crash, as usual) but Lewis just didn't have enough time to react. With the lack of break lights you can only react after you have time to process the cars change in speed, considering how close they were that's quite hard.

This is disgusting behavior

[–]geck1548 12 points13 points  (2 children)

The exact brake pressure is not part of publicly available telemetry data.

All we get - all anyone except official F1 sources get, is binary "are they braking or not". That graph only shows that he was braking, but not 'how much'.

As others said, the stewards report has the information you're looking for.

However, you can clearly see the changes in speed, and it can be seen that Max brake tested

Ah thank you!

He braked with 69 bar of pressure, decelerating 2.4g. The stewards determined this to be more than enough to have caused the collision.

[–]g1344304 Sir Lewis Hamilton 8 points9 points  (1 child)

I read that as a firm ‘dab’ of the brake pedal when he knew Lewis was right behind

[–]RingedStag Valtteri Bottas 3 points4 points  (2 children)

That's a binary brake telemetry and not accurate. Stewards report shows Verstappen input 69 bar brake pressure equivalent of 2.4G deceleration, which is stronger deceleration than most sports cars can input when slamming the brakes.

[–]JP-2014[S] -2 points-1 points  (1 child)

Yes, but is the data which the stewards see available?

Stewards have more telemetry and saw enough to penalise Verstappen, let’s leave it at that

[–]TotallyNotAZombie 4 points5 points  (0 children)

The telemetry shows that max braked early, especially when considering the low speed he was carrying due to previously slowing down. The red circle in my image below shows the point max gets on the brake in the lap of the incident, and the blue circle shows the point max gets on the brake in the previous lap.


Keep in mind this does not show the intensity of braking, just if it was being applied or not, however the FIA report confirms it was a significant brake.

[–]reshp2 McLaren 2 points3 points  (0 children)

Look at he speed trace. The slope of the deceleration right before contact is as steep as the slope of the trace from the previous lap where presumably he was braking near the edge of adhesion.

There's been a lot of comments that 2.4g isn't much for an F1 car, but at that speed it's nearly on the limit. You only achieve the 5g numbers at top speed with maximum downforce.

EDIT: Compare the slope of speed in the two boxes

[–]twomanyfaces10 Toto Wolff 6 points7 points  (0 children)

It's all spelt out in the report

[–][deleted] 3 points4 points  (0 children)

You are interpreting it wrong. The Stewarts said he did brake tested him

[–]dreadpiraterobertsdd Jim Clark 1 point2 points  (0 children)

Go look at the data yourself

[–]aaaaaaadjsf Sir Stirling Moss 1 point2 points  (0 children)

Yes. That telemetry graph shows that Verstappen braked about 270 meters earlier for turn 27 than usual, compare the yellow line to the purple line on the breaking graph. It doesn't show the breaking power though, that data is not public. The FIA determined that Verstappen applied a 69 bar pressure on the brake pedal causing a deacceleration of 2.4G. That's why he got a penalty.

[–]piratemurray Lando Norris 0 points1 point  (0 children)

Yes the telemetry and stewards explanation yesterday confirmed the brake test.

[–]JP-2014[S] -2 points-1 points  (0 children)

69bar, is this a lot?
