Major key is not to lock tyres. Once they get locked, your distance gets mutch longer. So the challenge is to find the right amount of brake pressure you apply to the pedal. At high speeds you may be able to apply more pressure, because the downforce gives you (and your tyres) more grip.
Another thing is to stricktly stay on the racing line. It has more grip, especially when the track is drying! You may be forced to change to slicks, simply because the wets get cooked on the dry racing line but the rest of the track could still be wet and very slippery!
One more hint for Steeve (and other new guys):
We use no speed limit in the pits, but the limiter engages automatically when crossing the entry line. So you need to apply a button to the wheel to disengage it after crossing the line. Of course you must be aware of where your pit spot is located. You get the final position of this spot when you enter the event (practice session), so you should practice entering the pits and your spot a few times in the pratice or warmup session. NOTE: Cars can't collide with each other in the pits, but before end after the entry/exit lines.
Here's a vid to demonstrate our pitting procedure with no speed limit (using the F1)...
