The hardest part of brake cleaning is lifting the car and removing the tires actually. You can bring it to the gas station with a lifter and have them mount your car, remove the tires, pads/drum cover tapos ikaw mag spray ng brake cleaner. It's nice watching all the dirt go down.
Havent tried mag1 but i guess it should be okay for the daily grind. The usual thing people should watch for in brake fluid is it's hygroscopic properties. Some fluid types can be more hygroscopic then others so to keep your brake system clean, you'd have to change more often to get rid of corrosion inducing and brake feel lessening moisture buildup.
