well i cant figure out which screw thing to turn on my brakes
(back).. They work HORRIBLE! There are two screw type things on the back of my recon on the drive shaft. There is one on top of the other. I cant follow the wires they spin around eachother. One of my friends said that they are both for the back. Even if they are i need to know which is for hand and which is for foot. There is a little box on the right handlebar that has oil in it for the front brakes?

 

Yes the two adjusters are for the back, left handlebar lever and foot pedal. But before you begin, I would take the brake apart and clean it out, more than likely they are seized up or full of dirt, they will work the best when everything is clean and lubricated. When you take it apart you can see if the brake shoes could be worn down too much.
