Red Bull RB13 TAG Heuer

[TNTHead]

In Ted Kravits post race notebook he says that it was a broken brake duct. Some re-engineering needs to be done if you ask me.

Verstappen had an rear brake problem as well in Bahrein. So problems for Red Bull could be bigger then we think ?

[TNTHead]

Indeed. Although Helmut Marko put the brake problems in another perspective: http://www.auto-motor-und-sport.de/form ... 22736.html

He suggests that they use the brake heaters to keep the rear tyres in the desired range.

it would be important to know if they have some aero problem in the ducts, some flexibility issue or they simply are running over the limit with the intake sizes

but the first problem was after a restart from the box the second after a restart from the safety
these are moments where at low speed the temps go high ( even if they don t brake that much under the safety it could be a problem of the warm up laps behind the sc )

so definitively not an external damage, what do u think?

From the link TNTHead posted, it reads as if there was a crack in the cake-tin or another component that led to overheating of the RR brake assembly. Hard to tell as the translation isn't great. RB is using heat from rear braking applications to keep the rear tyres hot.
Maybe someone with a native tongue can translate better.

According to Fia Event list Verstappen returned to old ICE before the Sochi GP

According to Helmut Marko RedBull is on the absolute limit with the brakes. They need to reduce cooling to a minimum because they need all the heat they can get to warm up the rims/tires. Especially on the rear end. RB13 has huge problems getting temps into rear tires. Ricciardos failure came from a broken heat sensor at the brakes that lead to quick overheating.

B-spec needs to deliver... Btw... rumors are that the B-spec is around 1 sec per lap quicker...

From what i can read (being Dutch, not German tho), the article wrote there being a crack in the brake-drum. That caused hot air to blow onto the "Sättel", which in brake-terms look to be the brake-calipers. To me, it sounds like something unfortunate, being on the limit of engineering. Altho, leaving a bit more margin couldn't hurt aparently. Another explaination could be too much stress on the failed part (temps too high, or in combination with vibrations, etc).

And I guess the need for more aggressive heat collection from brakes to tyres comes from relative lack of downforce vs Mercedes /ferrari.

So yes, a better chassis will solve myriad problems.

Yes, Ric confirmed this several times in interviews. RB13 lacks downforce (especially at the rear) compared to Ferrari and Merc.

??? If they know how to find a full Second(!!!) why didn't they do it in the first place???
So in other words for 15 Months they developed a car that is almost 1,5s down on Merc/Ferrari and after having completed the design, having it run in races for just 6 weeks they suddenly know how to find a full second???!
Really?

Nope. More than likely They started B spec development 6-8 months ago, maybe more.

There was a pirelli document that outlines the performance of the teams simulations, I don't think teams were named. However any team could reasonably see where they landed based on knowing their own submission to pirelli.

On top of that, most teams will parallel development of a few concepts in early phases. They may have re-started one and found it more successful than the one they had committed to at the time (the 13).

If they learned something new and found a full second or more 6 months ago they could have started the B spec.

This actually explains the bare naked and simple detail of the current 13.

If they were behind on the car or had some good concepts, they may have chosen to put out a simple stable platform until those solutions/the proper car could be properly designed.

Well, that is what "development" means
