The break service light is staying on my vehicle and I have no idea why. Do you think it has something to do with my brakes maybe constantly being on a little bit and tripping off the service light. Do you think it's worth having it checked out what it's been this way for around a year and I've had zero problems I just was asking because I want to figure it out.

I keep charging my battery and it just will not hold a charge longer than a day. Does that mean that the battery is no good or what does it mean about the battery. I'm guessing that a battery cannot be fixed but maybe I'm totally wrong. I'm very new to fixing cars and such so I need some help in this case. If you think I should just go buy a new battery that's what I'll do but I just need some help before I go and spend a bunch of money on something I don't have any idea about.

My battery has been getting a lot of corrosion over and over but I cannot stop it. Is there a way or something that I can put on my battery so that the corrosion doesn't come back. There has to be some sort of liquid that I can use on the battery terminals that will stop the Cronin from occurring.
