Need Help
 

Just bought a Randor Traveller! I know little to nothing about bicycles, but would like to repair it. The only problem currently is the back brakes. I believe it needs to be rewired, but would like some other suggestions. I would appreciate some help if possible!

Whats happening: Bike brakes have tension when first pulled on the hand brakes(?), then lose tension. Back brakes do not press in to hold tire to brake.
