Where does movement stop? If end piece is stopping at the C-clip groove, have you checked for burrs left from fighting the C-clip?So I got the bugger off with two very small screw drivers, it appears to be not such a springy spring clip and seems to have deformed into a oblong c shape.
Problem now is the end pieces are not coming off either! I cant seem to see why.
Does anyone have some instructions for taking these apart they are Cleveland CM10-5 brake cylinders. Google comes up with the CM 10-19 instructions but I thinnk there maybe some differances between them.
