Brake flush or brake bleed?

Kamillio

I am taking my car up the track soon and I want to put motul rbf 600 in brake system.

Everybody seems to be justbleeding their brakes and adding maybe adding a quart of new brake fluid. But that doesn't really replace all of the fluid in the system. Seems pointless if you are going to the track and want to upgrade to a better brake fluid.

Now to do a brake flush you need more than 3 quarts of the fluid, plus the fluid to flush the system. Way more expensive to say the least.

I would rather do the brake bleed from the money point of view but brake flush is what makes sense for me to do to bring the car towards track readiness.

Any thoughts?
