There is a fuel leak in the engine compartment. Have a mechanic look at the engine.

You have either a cracked heater core or bad heater hoses that are allowing antifreeze to enter into the vehicle............

A burning smell from a car's brakes means that you are braking very hard or there is a electrical short circuit in the car. Another reason for a burning smell may actually be coming from the car's heater.

You most likely have a leak or your car is overheating. If you are smelling it in the car then in all probability the heater core is leaking.

If you smell antifreeze in the passenger compartment of your car your heater core is probably leaking. It's under the dash somewhere ( depends on the make and model ). Another symptom of a leaking heater core is moisture build up on the inside of the windshield when you run your defroster.

That "mist" is more than likely coolant steam coming from a leaky heater core. Replacing the heater core is your best option.
