Bill Frederick doesn’t build Undercover cars, he builds Elite. Billy Torrence now builds Undercover cars. NahNahTounge

That said, You can count on me verifying and if so I’ll want to know why since Bill and I have had the conversation years ago about why Undercover race cars came with DOT 5 fluid in their master cylinders and the benefits of this fluid over all others.

A few weeks back the throttle partially hung on my wifes car in the shutdown area. She got it stopped ok then shut it off. That was on a Saturday. She raced it the rest of the day and Sunday and on the ride home commented that her brake pedal was spongy the rest of the weekend. I figured it must have boiled the fluid in the caliper when she was getting it stopped. So we bled the brakes and the pedal has been good since. Wilwood 570 fluid that we flushed at the beginning of the season.

He will be glad to tell you...

And Torrence is not in the dragster building business as of yet...not for public anyway

That’s not what he said in the interview. I’ll be speaking to him in person about it this week.

Garbage fluid like the others... burnt, black and stinky after 1 season.

Mike, I like that idea. Maybe even a simple little deflector that would direct some additional airflow to the rotors.


Great idea, but.....even with air forced over the brakes, heat transfer takes some time. A 200 mph run will cover the shutdown area in pretty short time. Very little heat transfer can happen in that few of seconds. They work very well in road race cars because you aren't trying to shed the heat you are creating now. You are getting rid of the heat from that last brake exercise.

I do not know of anyone who ducts cool air to the brakes but it should not hurt anything.
With beadlocks it is probably a relatively "Dead Air" space around the brakes. Venting some air in there would probably help.

"Dunning-Kruger Effect"
-a type of Cognitive bias where people with little expertise or ability assume they have superior expertise or ability. This overestimation occurs as a result of the fact that they do not have enough knowledge to know they don't have enough knowledge.

Before you argue with someone ask yourself, "Is this person mentally mature enough to grasp the concept of a different perspective?" If not there is no point to argue.

Want to know something interesting, every Cup car, Indy Car and F1 car use 5.1

Must be true because I read it on an internet message board posted by a nobody that does not race or wrench on one no mind every Cup car, Indy Car and F1 car. Roll Eyes

That said, I don’t care what brake fluid they use, I use the same brake fluid that my professional drag race chassis builders installed from day one in my cars same fluid that comes in every COPO Camaro too.

I’m pretty sure Ed said 5.1 like a 1000 times

Those coming here to “Tech Talk” looking for advice want the truth and the facts, not opinions. Be Right Back

Some grown ups actually want to have a conversation without a drama queen stomping their foot continuously hollering "look at me" "I know I'm right."

Anyone that needs to repetitively make their point and won't tolerate deviation from said point needs MENTAL HELP.

I give my OPINION to others all the time too. I just DGAF if they throw it in the garbage can. Why care? And if they find out I was right the hard way, I still DGAF. I think others are entitled to ignore good advice. Otherwise we must all wait for the guru to speak, and then bleet away like good little sheep.

Me personally, my bull stuff filter is over whelmed.

RIP

This info is from Mark Williams Enterprises: Wink

https://www.markwilliams.com/d...ke-installation.html

"There’s also the matter of brake fluid, with DOT 5.1 preferred due to its ability to withstand high temperature without “boiling.” DOT 5.1 is hygroscopic, as opposed to silicone-based DOT 5.0, and has proven to work well in drag racing environments.

DOT 4 (non-silicone) will also work fine for most drag applications. Changing the brake fluid annually is another well-founded recommendation. Using a pressure gauge to verify line pressure is another valuable tip."

https://www.markwilliams.com/braketech.html

"Use of DOT 4 or 5.1 fluid with a high boiling point and lubrication for seals and pistons is recommended. Do not use (DOT 5) silicone fluids."
