Its a Garage, NOT a house, the garage is no bigger tthan a normal sized living room. This is a TEMPERARY solution to power just a SMALL part of the garage that is nessessary to be powered until i can get some wire and a breaker box and run a new one. On a legal standpoint its prefectly fine to use a extension cord up to 90 days. and as stated the current the garage is drawing is smaller than that of a Toaster.
Why replace two front brakes? the other side is fine and replacing it is just added money. The pads on the seized caliper surprisingly still have plenty of pad materal left.
1. I just hope to goodness(for many reasons) that you don't ever have a fire. If it happens while you have things rigged up the way you do now, heaven help you when dealing with the insurance company. Even if you rewire it yourself, the same applies.
2. It doesn't matter how "good" the other pads are. Brakes are done per axle for a reason-not the least of which is that uneven brakes can cause the car to "pull." Brakes are one of the most important safety systems on your car-don't mess around with them. Heck, every time I've bought pads they came as a set of four(i.e. enough for one axle). No reputable mechanic will do your brakes on one side.
Honestly, though, I don't know why any of us continue to bother because it seems like you already have your mind made up about what you're going to do before posting here.
