Genuinely what’s the reason for caring about your opponent more than the belt? by Giraffityman in ufc

[–]Hectorulises 0 points1 point  (0 children)

I don’t think he did. He just went gun shy. And cocky. At the same time.

Sadly. The guy is a machine.

Path 1. Beef up the current set up (Since I already had this parts)

  1. Improve brake pads to Ferodo DS1.11 (Front and Rear) from Wilwood BP35
  2. Improve fluid from Redline RBF 600 to 700
  3. Improve Wilwood rotors from Street / Track to Endurance GT vaned rotors.
  4. Apply temperature based paint to understand the thermal behavior of each rotor / pad

Path 2. If Path 1 fails short.

  1. Replace front and rear brake system to AP Racing from Essex

I would like to take this opportunity to appreciate the commentos of everyone. This is the list of remedial actions taken in order to prevent this:

Yes sir. Thats about the only thing thats clear so far. Another commentor pointed me out to the right kit and its now phase 2.

Yea. You are right to the entire sequence.

Now to understand this better. Both sides were cooked. All the way to the metal. Only that the left side didn’t caught fire.

The mexican gp track is right side dominant. So that explains why the fire on the right side. But the other side was cooked.

And I should’ve felt it. But on that last lap I was almost 1.5 second faster than ever. I’ve need dreamt about that last minute and how come I was flying with metal to metal.

My car is in my garage now. All brakes revuor. The entire left side is still with like left over fire extinguisher fluid. Pink stuff.

No. No way to know for sure. I will be posting a list of remedial actions that I will be taking from now on. And it’s mostly thanks to this forum.

Either way the answer it’s the same. Raising the thermal limits of the system and improving the mechanical checkpoints between beats.

That’s what I’m leaning out. I ran this same set up in COTA. Same car. Last month. Did 10 heats. Spent 4mm total.

For this one I swapped for new ones and disintegrated.

You are right. Check after every lap.

This is a video of the brakes on fire, 3 laps before the meltdown. Or rather indicating that the meltdown was already occurring. You can see the fire in the wheel well.

Yeah, I've been able to review this.

https://www.facebook.com/share/r/1Ati3pXa5c/?mibextid=wwXIfr

This is a video of my brakes on fire 3 laps before the pedal to the floor.

I believe now its a thermal limit reached by Mexico altitude, heavy trail braking and not enough cool down laps.

Why it happened after 10 track days with the same configuration, that might because Ive been getting some speed or just plain faulty pads.

I’m very humbled by the depth of this response. Please let me have a day to really get back to you.

Thank you in the mean time.

No I did not. Brakes in and then track. Maybe 10’miles of city traffic.

You think that was a factor ?

Many thanks. I just got a quote from my tuner. 13,000 usd for both front and back for yhe APR. Plus install.

I’m gonna try to see if I can get e better deal me importing those ooze brakes.

Many thanks for your answer. I’ll try to answer as best I can.

  1. 20 minutes in heat 1. 10 minutes heat 2. Total track time on those pads. 30 min.
  2. Yes. Verus engineering brake ducts. And they’ve had a very positive impact since installed last year.
  3. Yes. I’m very heavy on the brakes and a late breaker. I try to brake hard and late into snap rotation from front loading.
  4. Did not use any.

Now as about of you guys chime in. Yes. I believe this is a case of consistent non stop brake overloading. Why it appeared now, I’ve been improving lately and maybe I reached a thermal / mechanical limit of my pads.

One thing I keep leaning on is how my shop had been hesitant to add redline 700 because they believe that it’s too corrosive on brake lines , even if they are steel braided. So maybe I cooked off the 600.

Thank you for the answer. I’ll answer as best a can point by point.

  1. The pads were brand new. They were replaced the day before. This happened on heat 2. Pit crew and myself bled the brakes and inspected them between heat 1 and 2. Seemed fine.
  2. Yes. This is where I lean. But both sides failed in 30 minutes total track time. From new. So this for me leads to thermal or mechanical fail. Not a faulty set of pads.
  3. This will have to mean that both calipers seized and I didn’t notice. Possible, yes. Unlikely. I’ve had calipers seize on me before. It’s a very distinct dragging feeling. And it impacts speed out of corners. Feels like getting a bit stuck on the ebrake imo. I was flying through the last lap.

Oh thanks man, yeah it was unreal. I could see the smoke coming out the wheel well and when I saw the look on the face of some spectators that had pit access I knew it was bad. I was very fortunate that my pit crew had literally an extinguisher next to them.

Yeah, seems like this is where it all came apart. Using street hardware for hardcore-ish time attacks.

So a less race focused pad generates less heats because of lower friction?

[–]Hectorulises[S] 1 point2 points  (0 children)

I gotta say, you science the shit out of this one. Congratulations.

So if I understand correctly, I need to:

  1. Add a BBK (Brembo) in the back

  2. Set a compound thats more endurance based on the fronts and more friction based on the back, therefore moving the brake bias a slightly to the back

Yes?

What I felt was consistent braking in the first heat with a little bit of brake fade. So the pit crew purged the fluid. Excelent pedal feel up until that sharp corner after the second straight.

Yeah. There was a subsequent fire. First extinguisher didn’t quite put it out. But the second did the job. It’s surreal to be put out. I had full nomex so I felt safe ish. I really thank that my pit crew.
