hand brake does not work

[Denis]

Everything seems normal but it still does nt brake very much.
The cable are good, the galippers level work too.

I need to bend the cable at max to get a little brake, but when the pads are tinner i lose brake again...

There is something in the screw and piston that it does not want to keep adjusted or auto-adjut  ?

I partout the rear galipper to clean them...... they are in good condition but the inside  pistons have losen srcew, my on my 90 the srew inside the piston was tight not lose....

There are almost the same rear galipper on my ex-90 and they always wored great.

thanks
