6000 DIESEL TRUCK

1986 GMC Other • V8 2WD Manual • 60,000 miles

I have a 1986 GMC 6000 diesel truck in great running shape, yesterday an alarm came on the dashboard and then I had to pump the hydraulic brakes continually to stop, I checked the fluid and it was just a little low, do they need an adjustment or something else?

If hasn't been fixed already check the master cylinder for being bad, sounds like it is or you have aleak in the system
