brakes losing power assist?

I went autocrossing again yesterday. It was actually a school for it. One part was an acceleration and braking test. It was back to back hard starts and stops, some starts spinning some not. In the braking zone some times the brakes felt like they were losing their power assist. The pedal was very hard and the brakes took 10 to 20 feet longer to stop and I could still feel the ABS pulsing. Other times the brakes were fine and because I was anticipating the longer stop I then stopped 15 ft short of the spot I was shooting for. I was wondering if the common brake and clutch fluid reservoir may have had something to do with it. I know what the ABS pulsing feels like, it was not that. The pedal was rrreeeaaalllyyy hard and the brakes were horrible. Maybe over heated the fluid or something. Ten minutes later they were fine and stopping like a champ. Anyone else felt this?

BTW I ended up with the FTD fastest time of the day beating a bunch of sweet cars, lotus, audi, bmw, miatas, minis, g8, genesis, mustang, and a bunch of others. I love my car

Brake fade? I wouldnt think it would have to do with the clutch fluid. The problem there lies in the fluid boiling causing the slave cylinder to starve for fluid. Do you have headers and prehaps removed some heat shielding? Then I think that may be possible. But I would say get some better pads and try again.

does brake fade make the pedal effort really hard, this is the first time I've experienced this?

Yes brake fade makes the pedal effort seem harder.

You have found the limitations of the stock braking system.

I think you know what you need to do if you want to keep driving your car like that.

First off, don't attempt that training exercise again, the brakes need airflow across them, other wise they will be trashed soon and your car will sound like the mail carrier's (squeak sqeak)

Secondly, change the brake fluid to that expensive stuff all the track guys use. It's the Castrol stuff I believe, has a higher boiling point.

As was said earlier, you have found the limits of the factory Camaro brake system. Just because it says Brembo doesn't mean it can autocross or roadrace. Many others have learned its limitations the hard way as you have. Aftermarket packages are out there to be had. You will pay well for a high quality system and do upgrade to stainless lines and brake fluid.
