Brake loss at high speeds

[86.5 7MGE]

So upon inspection of my system I notice that I do need to do a complete brake line flush due to the brake fluid looking like a dark brownish color in compared to a clear water color when it's fresh. I have also found a cracked line in my left rear side exposing the braided lines. So I'm just going to order some new Techna Fit performance brake lines all around. I also noticed on changing out my pads that they had some rust on the inside of it where it touches the rotor. This will be the last time I will be able to get my rotors resurfaced so next I'm going with the performance rotors. Eventually I'll be able to save up for a front and rear big brake kits; it's crazy how they cost as much as a high end turbo.
