Mercedes AMG F1 W04

Did they note if it it is in the upper or lower suspension arm? I'm guessing they run in the big cover over the drive shaft.

So... is it normal to have this many issues, or is this indicative of Mercedes employing some rather extreme solutions on the car this year?

I suppose it's normal to have some issues, but maybe not quite this bad. That coupled with the design changes to the car means it's unpleasant but not yet time to have a heart attack.

Hydraulic issue for sure. Interesting how it only affected the rear though. Are F1 braking hydraulic systems independent front and rear?

No, that is why there is a brake bias adjuster. I am wondering if the brake line failed, or if something in the bias adjuster did?

Do the regulations allow the brake hydraulic system to be tied to a hydraulic suspension system? I think no, and I remember having these talks last year, but forgot the outcome.

The car, has changes in the rear suspension, i think that the upper arm is mount higher to the chassis. This leads to changes in the hydraulic connections to the brakes. And there is the problem. The team has decide to change all the system, against future problems.

That's what I thought which is why only the rears failing doesn't make sense to me.

Bias adjuster failure may fit?

Well it looks like he had the brakes on.

Just a question from a technical newbie: what exactly did they do wrong with the coanda exhaust on the w03? Was it just the sidepods that were not designed for it, like Ross Brawn said?

I don't see what a brake bias adjuster has to do with only one braking hydraulic system. A brake bias adjuster can easily act on two master cylinders (one for the front, one for the rear).

And of course front/rear hydraulic circuits are independent in a formula on car. Why there would be 2 brake fluid reservoirs mounted in front of the chassis otherwise?
Plus it would be crazy to race a car with a single brake circuit!

I was thinking the same, so if one of the brakes fails, there are another 3 (or 2 ) ready for an emergency...

Focus on the car

How about this then:

Here's the footage of the crash.

Thanks for the pic of all wheels locking up. An article confirmed all wheels locked up as well. I'm wonder what could have lead to such a hydraulic spike that would cause all wheels to lock.

[Shrieker]

From the slow mo, it looks like he couldn't slow the car down initially when he hit the brakes, then he had to jam on them to make the car stop and the wheels locked. That's when the above photo was taken I presume.
