My 84 Z28 sat garage kept for 22 years. This is the brake fluid I took out of it. Suggestions here but should I gut the system or just flush the hell out of it? All new brakes/rotors/calipers/drums going in. I pulled the old fluid first to not contaminate the new. Appreciate any help

 

Start by inspecting all lines to ensure they are not rusted, busted or crusted. Flush some new fluid through it and look for particles. If you see any, probably time for new lines.
