I have MATLab on my computer, so that shouldn't be a problem. In fact, I just got done reworking an algorithm that I wrote to generate new ECU data tables for a project that I have been working on for awhile now. Anyhow, this is great information, I have to say. I looked through the paper. I will admit that the math is a little bit complicated, but I get the gist of things, I think. Thumbs up!

 

If you want to work through it yourself and need help email me! I would be more than glad to help you out. I tutor every level engineering class so I have a grat understanding of pretty much everthing, especialy MATLab lol. But you will need to look up the state space function, in MATLab it is ss(A,B,C,D) where A,B,C,D are your system state space matrices. Also it will helkp if you know how to use the syms function so that MATLab can do the algrebra for you. But yeah, give it a shot, it will definately help you in any dynamic systems and vibrations r controls class you will take. Btw EE are really good with this stuff too!

 

BTW if you would have those articles you would have noticed the first quote:

"Tires stop a car, not brakes. Even if that's a broad statement, full of caveats and qualifiers, it contains a crucial truth."

The bigger rotors and calipers stop the tire rotating quicker. However, just because the tire is not rotating does not mean you are not still going to be moving. You will need extremely awesome tires to match the performance of your brakes.

 

No, they don't.

This is wrong. The frictional force is related to the PSI of the system as the PSI of the system produces the normal force. As I have said before, making the pads larger does nothing as shown by the basic equations provided in those links. Increasing the size of the rotors and calipers does increase braking torque, I said this earlier or in a different thread, however this doesn't translate to lower braking distances. It will dramatically change pedal feel but the stopping distance is more an issue of the tires and the friction of the pads than anything else.

 

can we just leave it at , your only as good as your weakest link.

its a combo if different things. Tires, Brakes, Suspension/ weight distribution. So many variables when it comes to stopping and handling.

just get an upgraded design like slotted rotors and call it a day

 

+1.

I don't bother posting anything regarding brakes on here anymore cause Amby always tries to jam his thoughts down your throat. If you have different thaughts to him your wrong (apparently even if you're a mechanical engineer and know what you're on about!!!!!).

 

Yes, it's all my fault . I'm forcing people to read the links I provide and forcing them to read my posts.

Edit: After doing more research, while increasing rotor size does increase brake torque (as I said earlier), this does not affect stopping distance. It does however play a role in brake bias.
More links for you.

LMAO abby just give up; you are so wrong that its hard to withsdtand not correcting you. If brake are what stopped a car, and not the tires, then the brakes would be in contact with the ground. TIRES STOP THE CAR! BRAKES STOP THE TIRES FROM ROTATING! Shut up now because you are wrong. You cannot even read the links you provided well enough to interpret what they are saying. You want a real link, read mine posted on the last page.

 

Are you actually kidding me? How many times on this forum have I said the tires stop the car?
In post 19, I clearly state that. In other BBK threads, I clearly state it. Perhaps you should read the thread before calling people on things they didn't do. I was referring to this statement

not your statement regarding tires which I clearly agree with given that I said this

 

lol looks like it getting intersting in here.

Well forget the rotors then I just want the caliper for cosmetic reasons.

will i sitll need the giant 19' wheels for that.

 

If you're only looking for a cosmetic upgrade, you can get the stick-on caliper dress-up pieces (you've likely seen them on some sites, where they glue to your existing caliper and look like Endless, Brembo, etc. calipers...but don't actually do anything)

 

You'll still need larger wheels since it's rarely the rotor that hits, it's usually the caliper itself.

 

from my experiences, i upgraded both the tyres and the bbk (from mrt) and the stopping distance and performance has been significantly improved and brake fade is non-existent.

i upgraded the tyres first and noticed a difference and then combined with the bbk later, noticed a significant difference - especially driving through the hills

 

...

 

I'm guessing the BBK came with new brake pads? I'm guessing they were significantly more aggressive than the stockers (which by all accounts aren't very performance-minded pads) thus, combined with stickier tires, resulted in shorter stopping distances. There's also a difference between better braking and perceived better braking.
