The "Pedal Dance" testing

last time i did it was in the summer..

the only thing that changed is that i'm on winter tires right now and my TPS light is on, could this be interfering with the sequence?

also how warmed up does the car have to be, and will it simply not work if the car is cold?

I've tried it a couple times this winter and I've figured out that because it runs off the water temperature, you have to run it properly hard and then turn off the car-> turn it back on -> then do the pedal dance. The water temperature normally doesn't get warm enough for me to do the pedal dance with standard driving this time of year

Correct, you need at least 160F

I've driven the BRZ in snow a few times... I would personally never drive it with the aids in an ultra low traction environment (I was on OEM Primacys).

Pretty cool, just did it and worked on first try. So this leaves the cars braking bias to what? 70% front?

Any reason as to why we should use lower friction pads on the rear? Thanks

You're not supposed to, but if you do, you have to do the pedal dance to disable EBFD (which expects same compound to be used front and rear). Please re-read @CSG Mike's post

- I tried trail braking mid-turn with the "normal" electronic aids off, but without the pedal dance. This resulted in a spin; the car literally locked up the rear brakes. My speculation is that the car recognized the fronts locking up, and put additional force on the rear brakes. The problem here, is that I had purposely put a much lower friction pad in the back, so it kept sending more and more brake pressure to the back, until it just locked. Once it locked, it stayed locked, even though I was not stepping on the brakes.
- I tried this again a few more times. Same result.
- I then tried again, but with a rear brake bias. This time, pressing on the brakes mid-turn or trail braking always resulted in the car straightening out and/or plowing.
- With the pedal dance, I can trail brake or brake in the middle of a turn for rotation just fine, regardless of pad setup.

In any case, unless you really know what (and why) you are doing, you're probably better off using the same compound all around .

Thanks, i thought so. I recall driving my frs at the track back in 2012 and not really having so much skill as to notice these things. I asked because I was planning on getting a set of track pads and wanted to hear some suggestions or advise first.

Let us know when you want pads

[yomny]

What do you recommend, I won't be using for street but I will be using with stock rotors and calipers.

PM me with the tires you run, the speeds you see in braking zones, and your experience.

The VSC intervention in the all off mode from 3 sec press of TRC switch, normally available will allow almost all but the largest of slip angles, and allows you to be sideways pretty much in most all situations...

I don't know if it has been mentioned yet but pushing the button does not reset this either. What is worse is that the lights go off so it gives you the false impression that it does. It appears to require a restart.
I routinely make a u-turn on my way to work because of a "right turn only" at the bottom of an off-ramp, and I never slide when I do it.
This morning I engaged this at the left I take to go onto the highway and once I hit the highway I stabbed the button thinking it would turn it off and drove almost all the way to work like that. When I made my u-turn, I spun the tires and slung the car around it, which has never happened before. Good thing I didn't need that particular nanny at any point on the way.

I used this for the first time in autox. It makes pad choices more obvious of what does not work. I could not get the pile to trail brake to save my life. Brakes are so front biased on the sprint kit.

But point was you could not really tell before. Now I can't get away running those turd hawks on front and OEM rear.

Need to switch back to 1521 and see if its any better.

I will never do the pedal dance again, it almost resulted in a very bad weekend for me. I thought I would give it one more try in one of my time trial sessions this weekend. Going off the banking at TWS into turn one, about 130 down to about 60, I braked as deep as I was the session before trailing into the corner and ICE mode kicked in almost putting me off track. Later that session it happened again at a less high speed section of the track. Didn't do it again the next 5 sessions and never had a problem. I see the traction light flash on warm up lap sometimes, it might during the session I never look, but I never notice anything that would effect lap times.

So you run, just with the 3 Second full off and no issues?

How aggressively did you trail brake? IMO it's the wrong way to drive the car...mostly because that induces ice mode. It's worse if you've got a big front bar.

I had more ice mode issues than most - pedal dance or no - until I started braking in a straight line. If I trail brake now, it's maybe 10% of the brakes or I just lift and use the tires to scrub speed.
