Why do you think a brake pedal gets soft after repeated hard braking?

Stasis machines cooling vanes into their aluminum hats (big picture warning) ...
Unfortunately, I'm only using their hats in the rear.

Re: Why do you think a brake pedal gets soft after repeated hard braking?
to all of you guys giving different opinions on the issue of soft brakes after hard use
remember that the brake fluid is hydroclastic
which means it creates moisture
under heavy use it becomes vapor vapor is compressible
that's why your pedal feels soft
try replacing the fluid before you use the brakes that hard
but most definitelly learn to drive and balance your speed with the throttle so you don't have to abuse your brakes

Re: Not abusing brakes at Road America
Whether you call it abuse or just extreme service, it really can't be avoided.
That straight at the bottom of the pic is the longest straight on any road course in N. America.
The shorter straight in the middle of the pic is all downhill and ends in a slow 110o left turn.
The shortest "straight" is in the upper right, but the entry is the 100+ mph 45o right hander at the top of the pic (the Kink), and the straight ends with a slow 100o right turn.
Top speeds at the end of all three of these straights is nearly identical, and <u>very</u> heavy braking cannot be avoided.

My instructor doing 2:46's with me in the car....
....didn't pull as many braking g's as I did when I was really crancking on the brakes.
When I really stepped on them, the car just hauled to a stop, and I was running a 3:04 or so.
He used significantly less braking pressure, just started his braking a little earlier (which he would have because he was running faster times), but he would carry so much momentum through the corners and be on the gas at the apex and just driving it out of it.

In your car or his?
And I hope you meant 2:46 :-)
The Corvette in the in-car camera video of this SCCA Speed World Challenge race at Road America spends a lot of time dicing with an Audi S4. Their clean laps were 2:25's (Wow), and that's on the Toyo T1-S spec street tire. I imagine they were 150+ mph at the end of the straights and that much harder on their brakes.
It's an interesting video. The Corvette looks like he's braking the way we did. At the end of the straights, he usually gains a couple of car lengths on most of the other cars, only to lose the advantage on the corner exits.<ul><li><a href="http://bbs.sccaproracing.com/ubb/Forum2/HTML/002381.html">Speedvision Videos</a></li></ul>
