Brake questions

[MaSnaka]

Guys,
I'm having trouble getting my car stopped. For years this has been the issue. In fact one of the first things I noticed on my first drive was wow the brake pedal really needs some foot pressure compared to my truck and modern day drivers. This has been on my wish list but recently it moved to the top.

My car has the MII 9" front rotors and 10" drum rear brakes, no booster. Not racing on the track or anything but it takes a lot to stop. A couple weeks ago I blew through a red light that had changed on me because ultimately I was going too fast, but it was like there was no effort from the brakes when I stood on the pedal.

I was looking things over today and pads and shoes are intact, there is fluid in the MC but it is brown and atleast 5 years old...perhaps cooked. Would that be the problem? I did have to replace clutch fluid because it was in the same state. The pedal is not spongy, just doesn't want to grab.

I know I can upgrade the whole system for a $2,000.00 + or - investment. But I see that these are original brake sizes for Mustangs and the like which outweigh me by 1000 lbs or so. Would I be wrong to think the system I have is capable to work acceptably well? Or is the high $$$ full upgrade in my best interest, ie Wilwood 11" front and rear with a new MC.

If you have any ideas that you think might help please let me know thanks.
