Freewheel spins both ways cant peddle no were how
The freewheel has a ratchet pawl (an internal, spring loaded lever) that would normally engage gear teeth in one direction and click over them in the other direction. This is just like the action of a ratchet wrench. You might have a broken spring or broken pawl - in which case you will have to replace the freewheel---- Or it might just be dirty. Spray some WD 40 inside it (spray through the small gap between the round part that moves and the round part that doesn't. If that doesn't work, you'll have to replace it.

Loosen the little nut that hols the cable at the break.. Pull the cable out a little bit with pliers.. Tighten the nut at the break..
Thus taking a little bit of slack out of the cable and now the break will work properly..

Understanding Sag
In order to let the suspension work properly, we allow some of the rear-wheel travel to be used when supporting the rider's weight, this is called 'sag'. The basic idea is to have around 10-20% of your bike's total travel as sag. This allows the rear wheel to drop into dips in the trail and maintain contact and traction.
Adjusting Sag on Rear Suspension
Changing the amount of sag in the rear suspension is done by increasing or decreasing the spring rate of the rear shock. The rear shock's body is threaded and you will notice there is a nut on one end of the spring. Turning the nut in the direction that compresses the spring will increase the spring rate and reduce the amount of sag. Turning the nut in the direction that expands the spring will decrease the spring rate and increase the amount of sag. Never turn the nut to the point where there is space between it and the spring, this may cause damage to the shock.
