Sorry for the nody qn, but why do you need to bleed the brakes before each event? What does this achieve and isn't this necessary (bleeding) if the brakes & fluid are stock?

Water in the brake fluid boils at 212 F, which is much lower than the boiling temp of any DOT brake fluid. The water boiling creates gas vapor which causes the brake pedal to be spongy or go completely to the floor - meaning you can't stop. To remove the moisture prior to each track event, it's mandatory to bleed or flush the brake system with fresh, moisture free brake fluid.

DOT 5.0 silicone brake fluid should NOT be used for hi-performance driving as it has issues that can make it dangerous. It also should never be mixed with mineral oil based brake fluids.

Thanks!
