cheers for that i'll have a look soon to see if is the problem thanks

hi ive just joined this site coz im in need of help ive jus bought a tzr 125 r 1992 4dl belgarda import..and have almost finished workin on it. the problem is the rear brake. when i brake the rear brake does work most of the time but some times it becomes soft and the rear brake pedal feels like its lost pressure and it jus touches the exhaust. ive bled the system changed the pads and dismantled the caliper and cleaned it. but it still seems to do this....however after when pressed the pedal when soft, and a few seconds later the pedal becomes firm again like the pressure has come back or something and i dont know what the problem is? i dont think there are any leaks in the system tho bcos the reservoir doesnt go down? and im not sure wheter this bike has a servo or not thanks jon
