Who can tell me the American brake standards?I hope the brake system of our team can fit in with the American brake standard.Thank you!

Amercian brake standard....what the heck is that?

[Composites Guy]

In America you must be able to lock all 4 wheels simultaneously when the brakes are applied. "Lock" means instantly, completely stop rotation so that the tires skid along the ground. This is the main rule for brakes!

A second important rule is that the brakes for front and rear tires be in separate hydraulic systems. This is so that if one system fails the other will remain working.

In addition, the brake lines should not achieve so high pressure that they rupture when applied in a panic by your strongest driver.

Also, brake lines should be routed through the chassis to minimize chance that they be cut. For instance a brake line routed directly under a drive chain would not be allowed. If the chain were to brake, it could cut the brake line and cause loss of brakes.

As good practice, you should design your brakes so that front and rear tires lock at roughly the same driver effort.

You might also want to think about what happens to the brake parts and mounts as temperature goes up. Be sure to look at floating brake rotors and decide if you need them.

You could consider a diagonal split as well (if master cylinders are the same size), if you are interested in giving up the balance bar.

Has anyone ever had a brake circuit fail with a balance bar in the braking system?

What happens? Does the balance bar cock at an angle and make applying enough pressure to slow down in a hurry difficult for the remaining circuit with no fluid pressure in the damaged circuit?

Best,

if the assembly is designed well, the busted circuit will bottom out and the other will apply.

We busted our front circuit once (poorly made aluminum lines) and the rears still worked. The car just didn't stop too quickly.

Composites guy, i applaud you on your patience. How hard is it for people to read the rules? I think all teams should be required to do a book report on the rules before they are allowed to compete.
