69 cougar brake question

Ok. I am now knee deep in getting this old cougar that has sat since 1994 on the road. I worked on the brakes this weekend. Bled the entire system (ewww... the old brake fluid looked terrible). They still feel pretty sloppy (no grab until the pedal is almost completely to the floor). I picked up wheel cylinders for the rear and plan on replacing those but wanted advice if there is anything else that you would suggest be replaced (rather than replace the entire system!).

Thank you in advance.

No, I am doing a 72 Mustang as we speak, all the wheel cylinders are rusted internally, the fluid is water contaminated and the m/c is full of rusty colored fluid, this all has to go, no short cuts, peel back the w/c outer boots and look at what the inside of the cylinder looks like, what is in the bottom of the m/c reservoir?

Thanks for the advice. After consideration and again looking at the condition of the fluid that came out of the system (ewww - looked like gray water) I decided to go for the entire system. New calipers, new mc, and a complete set of new stainless steel brake lines.. total cost about $250 but I am sure it will be well worth it. Hopefully getting the old brake lines off won't make me want to rip my hair out :lol:
