944 handbrake problem

[speedy]

put my rear arms on today and got it working fine only problem is when the handbrake is on there is about 1/4 an inch of movement backwards and forwards , seems to me to be the pads rocking on the inside of the bell , is this normal ? also when i take the handbrake off and spin the wheel it binds in one direction for a split second and then free's off , did not have time to investigate as i had to come to work , any idea's or even better a guide to setting the handbrake on the net somewere
cheers in advance
