I ran some practice laps at race speed the other day, blocks of 20. When I came off on the last run, there was smoke coming of the engine and it looked like fluid had sprayed from the brake reservoir, the lid was on tight and the brakes had been bled with new fluid, the only thing I had done differently was run the car with no bias to the back, ive had the car 3 years and this has never happened before, any ideas? I run on asphalt if that makes any difference
