Loosen the springs in cross patern. Then remove all springs. Jiggle the pressure plate loose and pull out about 6 inches will do. The rod will stick to the bearings located at the centre of the pressure plate.
Use a cloth to grip the rod (DO NOT use pliers) and pull them seperate. Remember to lightly grease the rod upon reinstallation
I removed the bearing from the pressure plate before painting, thats the hardest part I guess as it invloves some light hammering with a combo of appropriate sized wrech socket, cloth underneath to protect plates etc.
Washed the pressure plate with petrol than with soap and water and dried it.
The only reason I painted it is I know over time, the stock pressure plate will discolour and looks nasty like some old junk metal (uneven faded look) once exposed to the elements
