All right I have a stupid question but need the information because I had to help bleed ABS brakes and didn't know about what I put in bold above. The rest of it i know how to do.
When you open all 4 bleeders, fill the res, leave the cap off and keep refilling as it pushes the through and the air bubbles out, what is causing the fluid to be pushed out? the down and release method on the brake pedal or is it a function of the ABS that takes over.
its okay you can laugh but really I need the answer

I see people out there spending money on the car to improve it … If you spend half that effort just working on your driving skills, making you and the car work together as a team, then you’ll go faster – period. To make the car go a second faster on the track takes a lot more energy and money than making yourself drive it one second faster.
