i undid the break line to the front driver wheels break cylinder to change it but didnt finish because of a problem so i put it back. fluid had drained when i did, so i know im supposed to bleed it even tho i didnt change it but i didnt bleed it because i thought since the cylinder was leaking the air would come out of the leak. i drove the car then parked it. the next day there was a puddle of break fluid coming from the master cylinder, dont know if it is a coincidence or not bleeding the brakes could do that?
What would happen if you dont bleed drum brakes right? will master cylinder leak?
If you do not bleed the brake lines, when you step on the brakes it will not stop. It may swerve to one side or the other. Whichever one you took off will not be working properly. If it is leaking fluid now, you probably Cross-Threaded the fitting when you put it back on, or you did not tighten it properly. If you cross-threaded it you will have to replace the fitting. It is not a very good idea to work on the Brakes of your car if you are not sure just what you are doing. You can end up in an accident because you may do something wrong.

Coincidence.
You should not get leaks from not bleeding your brakes. You will get a spongy feeling brake pedal or one that needs to be pumped every time you go to stop.
The leak is probably from a loose fitting that you didn't install right when you replaced it.
Re do the fitting, make sure it is tight, and then, have some one help you bleed the brakes.
You do this by pushing down on the pedal, holding it down, and someone else opening the bleed valve at the wheel, they keep it open until some air and fluid runs out, then they close the bleed valve and THEN you let up on the pedal. Repeat this a few times, until the pedal is hard. You must make sure that the master cylinder is filled each time, because you will lose fluid when you do this. Do not let the fluid level get low in the master cylinder.
Remember, Do not let up on the pedal while the bleed valve is open or it will suck in air. Make sure you close if every time before you let up on the pedal.
Your leak is probably from the fitting being on loose or screwed on crooked, which can happen.
