Hello colleagues! 2 weeks ago I changed the clutch kit + flywheel, I installed Sachs. For several days, I have been losing pressure in the hydraulic clutch. I aired everything but it doesn't disengage well, agata, I have to do 3-4 pedals to get out of gear. The mechanic told me it's from the pump, not the cylinder. What do you know about this? I understood that the pumps are more difficult to break, many acquaintances told me that the cylinder is to blame, that it no longer runs properly...help.
