Lately I have been having trouble with my Honda Accord‘s battery draining itself after I turn it off. Subsequently I have to get somebody to jump it when I want to drive it around. What could be the problem, and what is a cheap and effective way of finding out how to trace the problem and fix it?
The black color is from the brake fluid overheating. The previous owner didn't do anything wrong, it's perfectly normal to have black/discolored brake fluid when you bleed them. If you really want to purge it out, then keep bleeding out the fluid until it comes out the ideal clear color. Just don't forget to keep refilling the master cylinder with fresh fluid, while you bleed: because it will get low bleeding that much fluid.
sounds like you have a seal perished in the master cylinder or the wheel cylinders,this will cause fluid to be black.check if there is fluid on brake shoes
this is a pretty normal occurrence. brake fluid is corrosive so over time it gets contaminated from the metal lines it runs through.although it is not really nessacary to flush and put in clean fluid.you can do this by what you have already been doing bleeding but it will take a lot of it do it from back wheel the right one as it is farthest distance from master cylinder. just keep cracking it open and forceing out fluid and add new each time it gets low and after a while you will flush out all of the dirty fluid
Bob is right, but you don't want to spend a lot on 18 year old car right? Thought so, I don't know how inclined you are in electrical matter? But try to think logically, what could run on your car without key beeing on? check all fans make sure they turn off like radiator cooling fan run indipendent of your ignition switch, tepm. switch control turns off your rad. fan also condenser fan witch means it may not be turning off even if you turn off your car. Another possibility is glove compartment lights(depress switch failure when you close the glove compartment in your dash.
