heres one pretty good oneHow do I change the brakes and hardware kit on my back brakes?
1 if you don't already know how to do brakes, why are you doing them?? Leave a safety item like that to someone who knows what they are doing. Even
2 IF THERE IS BLACK GUNK (like brake fluid or grease) THEN YOU HAVE A LEAKING WHEEL CYLINDER OR REAR axle SEAL THAT NEEDS TO BE REPAIRED BEFORE THE BRAKES ARE REPLACED
take this to someone who knows what they are doing.
