Strange Brake fade at track, Thoughts?
Car Info: 89 foxbody, 3170lbs with driver, 324hp
Brakes: Cobra 4wdisk conversion, stop tech "street pad", Power slot rotors. No brake ducting. No dust shield. Motor craft 500degree fluid, maybe 2 years old? I cant remember if we swapped it out when we changed the engine earlier this ear.
I drove my car to the track the other day, and after about 8 laps on the noon time session, They black flagged everyone for some reason, and we sat for about 5-8 min in the hot pits. I had no brake fade during the session, everything seemed fine (I was chasing a 96 stang' down and was driving the car, and using all of the brakes.)
After sitting for 8 min or so they restarted the session and I pulled up to the started, and had almost no brakes. After I determined that I wasn't loosing fluid anywhere, I babied it back to the pits, and started scratching my head.
It was bloody hot, I was having other non-related mechanical issues, and the day was just not going well. So I let the car cool for about an hour and called it a day. Well the brakes came back, and I was able to drive it home with no problems.
So what kind of fade was this? I have heard of pad fade and rotor fade and fluid fade. I have had older fluid cause fade, but that occured During a braking zone, not 10 min after
Maybe all the heat from the rotors had time to transfer to the pads and fluid during that period when we were stopped?
I'm going to change the fluid completely out anyway, but is it time for a "Track pad"?
