Front Brakes in the Wet

Postby JohnKing6 » Tue Apr 14, 2009 7:08 pm

Another thing we haven't said is the HUGE HUGE HUGE advantage hand operated, floating disk, frontbrakes are in the wet. In the final on slicks with a very slippery track, I was braking for turn 1 and turn 5 pretty much where I used to brake in the dry and still making the apex - everytime :-)

I won't tell you where else I was using them - that's a secret that I'll only share with GP10 customers :-)

Moved this discussion over to it's own thread ;).

Yeah the front brakes are vital in the rain - there's no need to slow the kart down with understeer ;).

Btw only front brakes only aren't too bad either at least in the dry - I had problems with my rear brake on Saturday so I drove about 5 laps in qualifying with close to 0 rear brakes. The main problem was that using only the fronts changes the handling too much - which is exactly why they help so much in the rain ;). In the dry holding on to the front brakes too long overloads the fronts and makes the back end loose - in the wet you hold on to the fronts a bit longer to make sure the fronts actually do something.

There definitely is a technique to using the front brakes, and you use them a bit differently in the dry and in the wet. I find that in the dry I get off the front brakes a lot earlier while still keeping the rear brakes on - in the wet I hold on to the fronts a lot longer.

How having front brakes changes the set up for dry and wet race, in your opinion?

For a wet race (which I am particularly fond of, also since the topic is 'Front Brakes in the Wet') without front brakes, there are always a few basic rationals, aren't there:

- More front track
- Less rear track
- More caster
- More weight to the front
- More starting tyre pressure
- etc.

Has having front brakes changed the approach to setting up your kart? well, for both dry and wet race.

Mikko, do you find the working temp for the front brake a problem? I feel on the Tony's its take a few laps (10laps +) to get it to the proper temp.
For the rear brake I usually tape up around the caliper to block the water and to keep the heat inside. Not sure how to do that to the front.

As to having front brakes changes the set up for dry and wet race, dont think so in my opinion.
Maybe the rear track we dont go in that much as before.

If your temp is only ready after 10 laps, it is because you are sing wrong pads...
The softer the pads, the more agressive, but this depends on the temp outside...
Normally what the brake is warm it doesn't get a chance to get wet... the wather damps of already when it touches the material....

Well can you imagine a circuit you are not only unfamiliar with other than the practice during qualifying, but then have brake failure when it was a time they only used rear brakes? I had this difficulty at a event during a endurance event in the early stages, but chose to wave to my team mate & point at the left foot that I had a problem & he should get a new kart ready & wait for a pit stop. In that period, I actually used my steering wheel as a brake believe it or not? Even at a hairpin I was able to slow it down enough rather than just sitting in the pits & losing more time.
I must say that when I had brakes working at the correct level in the wet I had no difficulties, but if they bit I had huge problems. Strangely this was at only one circuit where I noticed huge changes in the way the brakes were set up during a wet event & in the dry you wouldn't even notice.
