Checked all the brake line connections. Also checked the bleed valves. No signs of fluid leaking. I pumped on the brakes for 10 minutes and found no loss in fluid level in the reservoir. So, I don't think fluid is leaking out anywhere.

Given the comments above and no loss in fluid that I can find, I'll replace the master cylinder to see if that fixes it.
