I can tell you with a fair amount of confidence that it is your water pump leaking. I am having the same thing happen on my 1997 Chevy z71. I have changed many water pumps for the same reason. If you are mechanically inclined I would go purchase a chilton manual at the local auto parts store where and when you get the pump. Be ready for a full day job and also buy antifreeze and gasket sealant.
If the hose is leaking, replace it.
Failed seal. Replace it.
your slave cylinder is leaking,need to replace.
Your heater core is leaking, Need to REPLACE HEATER CORE.
The housing gasket may be bad. Replace the gasket.
remove the two nuts holding the master cylinder on the power brake booster
antifreeze smell inside car means that there is antifreeze leak somewhere. first check for wet spots under car when parked after running.if anti freeze is leaking from engine it will pool on the ground next check to see if heater core is leaking. that is usually the problem. if heater core is leaking, replace it

Sounds like heater core is leaking, replace heater core or bypass
you probably have a leaking heater core....you can replace it or bypass it
Find the leak and replace the hose/part that's leaking. It's a good time to flush your coolant system, too.
