Because you need to do it before and after every AutoX.  |
I don't do it that often. Before track days, even between back to back track days occasoinally, and every couple weeekends of autocross, or because I'm swapping pads...
Like I said, ATE is great stuff, and I'm not discouraging anyone from buying it. I am only making a reccomendation that you do two cars at once, so you mostly kill a bottle because it only has questionable usefulness once it is open.
IMHO you can't boil fluid at an autocross, even with 7 runs and morning and afternoon run groups. There just isn't enough delta V to generate the heat required. Even at HPDE type events it is tough. It is far more likely in both cases to have brake fade due to pad material overheating, residue deposit on the rotors, glazed rotors or air in the system IMHO.
Scott, lets shoot your infrared pyrometer at the back side of some calipers at the nesxt autocross and see...
Also, A freind helping is better than speedbleeders any day as they rely on a less than perfect seal between bleader and caliper to prevent air during recoil... Every time you use them, that seal gets worse and worse, increasing the likelyhood of air entering the system which is 10 times worse than water... |
I'm not disagreeing with your points. I've just noticed that after an event the Ford stuff leaves my pedal feeling spongy. It's not that I believe I'm boiling the fluid at an autoX, it's that the fluid saps water so quick that I boil the water in the fluid leaving gas in the fluid, hence the spongy fluid. If I fully flush the system before an AutoX, it's usually pretty good right after... but if the fluid's a few weeks old, an AutoX will sponge-ify my pedal.
Plus, I'm probably a bit hyper-sensative to the sponge pedal because I have big feet. If my brake pedal pushes down even just a tiny bit more than usual, I end up stomping on the gas. When the pedal is soft, I'll notice that I'm sitting at a stop sign, and my motor is idling at 1000rpm because I can't keep my heel of the gas w/o shifting my leg left to totally clear the pedal. This happened with the Motul, but it usually took months and several AutoXs first.
I've always said, I want a brake pedal that has zero travel... just a solid bar to push on that slows the car the harder I push. So while the Ford stuff works great brand new, I've found that I need to flush the whole thing too often to keep my pedal feeling the way I like it. Even with all the flushing, it's still cheaper than the Motul (which is why I'm giving the ATE a shot) but the hassle isn't worth it to me.
In short: the Ford stuff is a lot of bang for the buck, as long as you're willing to put in the work of flushing before every event, or if you're not as sensative to a spongy pedal as I am.
