The Ideal Brake Curve

What is the Ideal Brake Curve and what does it tell us.
When brake system engineers design a new brake system for a car, they start by creating a curve called the Ideal Brake Curve. This video talks about what this curve is, how it is created and what it tells the brake engineer.

This helps explain why the rear brakes on my Honda Beat are bigger than the fronts, while the inverse is true for my daily driver. These videos are excellent and make an amazing resource for people like me to learn from!

how do i create a break curve ??

[@philthehorror]

These videos are great! Thanks for making them. I hope you have lots of success with this channel. Thank you again for sharing your knowledge with us, Hubert!

[@mry82]

I might be a nerd for liking your channel so much, but I am okay with that.

[@CanadaLuke]

Love your videos, thanks for all your work put into making them! Please continue to educate us :D

[@curiash]

Thanks

[@anhnguyenthi7498]

thank your video, can you have other video explain more about ECE cure, f line groups and r line groups for design regenerative braking?

[@40NoNameFound-100-years-ago]

thanks for the video , how to plot this curve ? what is the equation for the curve and the lines?

[@micheleambrosini6079]

Hello, thanks for uploading such great videos. They are truly highly appreciated. However, I still have a doubt, and it is: why isn't the antisquat related to the results of the graphic. Thanks again.

[@samcastevens8044]

Anti-dive and anti-squat geometry doesn't actually reduce weight transfer. They only cancel out the suspension's response to weight transfer.

Where can i generate my own ideal brake curve?

[@alekseyponomarev]

Does having staggered wheels like on a Porsche have any influence on the curve?

[@samcastevens8044]

I am trying to put those diagonal lines representing friction coefficient / deceleration into Excel, but I don't know how to do it without creating a new series for each one. Is there a simple way to do it? This is a fantastic video, by the way!

[@suspensionsexplained]

The only way I've found to do it is to use a new series for each one. You end up with a LOT of series in the graph!

[@timy_11]

may i ask how you used excel to get the ideal brake curve? I read the text book he recommended but still don't know what formulas to use

[@mjh9150]

Is that graph something widely available? I'm curious to plug in my vehicle specs to see what the curve looks like (from an academic perspective).

[@suspensionsexplained]

Matthew, the curves I showed were created using a spreadsheet I created myself. The formulas are not very difficult and anyone could easily make a similar spreadsheet. I recommend getting a copy of "Brake Design and Safety" by Rudolf Limpert. I have the third edition and in section 7.3, he talks about creating the ideal, optimum, brake curve.

[@Levibetz]

@@suspensionsexplained Is there a chance you could upload a copy to a public google drive or something? I'd like to illustrate why people are regularly installing dangerous brake systems on aircooled VWs

[@edgarflores7491]

How can we make our own ideal brake curve?

[@_Mike_D_]

Do you share that spread sheet anywhere?

[@suspensionsexplained]

No I don't. Because brakes are safety critical systems, for liability reasons, I do not share these but the formulas are not difficult to derive or find in text books.

[@thedownwardmachine]

Anyone else come here from The Autopian?

[@UncleVom]

Yes but No, I'd never own up to being a member there, a different name to break the association. (-;
