Brake Pedal Fade

While driving my car in stop/go traffic, my brake pedal fades ALOT. Today I blead the brakes, and cheaked for leaks. No leaks, but while pumping up the brakes to blead them, i noticed the pedal would slowly fade. It fades faster while driving....
Ive only noticed this when the car is hot....
Ive been driving it for the past week and this just started happening today....

Theres no leaks so what could it be?
Master Cylinder?

If there's no leakage or discoloration in the fluid then yes, it very well could be your master cylinder. Crawl up underneath your firewall and look for the pushrod going from your brake pedal assembly through the wall into the master cylinder. Make sure there's no leakage there. Sometimes when MC's die, they like to piddle a little fluid back through the firewall into the carpet, which loves to eat paint.

You can obtain rebuilt MC's for cheap or a rebuild kit for even cheaper if you don't mind an afternoon project.

1320ride is an unknown quantity at this point

you could also have a vacuum leak if the brakes are vacuum assisted power brakes which most cars are. check for small vacuum leaks as well but my moneys on the MC as well.

Master cylinders can leak internally... The
