1991 Ford F250 with 44,000 miles, I bought it new.

Recently the brakes will fade if you keep pushing on the pedal after you stop. Added fluid (wasn't below that add line), which seemed to help, but it still does it.

The truck stops fine, they just fade while the pedal is in and you are stopped. They feel like they do when there is air in the line.
I'm worried that the truck may not stop so fine one day (especially when I am pulling the tractor).

I'm no mechanic, but my guess is the master cylinder.

Anybody offer some help on this one?

Thanks,
Kevin

Yes, you need a master cyl. Try to find a new one, not rebuilt.

I would suspect master cylinder, or your vacuum booster. The master cylinder shouldn't be too expensive, and with any mechanical leanings you should be able to change it your self. Good luck.

I appreciate your opinions and help.

I'll throw a new master cylinder in today and see.

This could also be caused by a little water in the line. Changed out a cylinder once anf found while bleeding there was water in the line. Which a Brake man told me Created Steam in the line which was worse than air. :confused:
