Low coolant level, internal or external coolant leak or faulty thermostat.
If a coolant leak were caused by brake work, I'd never have that person work on my brakes - ever. Just the brakes, I would think it highly unlikely that it would result in a coolant leak. If they were replacing the master cylinder, then I could see a possibility of someone inadvertently causing a coolant leak, but that would still even be a stretch.
Leak in heater core
A leak some where in the system, such as a bad head gasket, a cracked head, a leak from the radiator, a leak from the water pump.

First check the coolant level, a coolant leak would cause a heater to stop working- assuming you mean the blower is blowing but it isn't hot. A stuck thermostat will also cause you problems with your heat.
