Tommy is correct. The CNC units are reliable if properly aligned. I have an aluminum one for the clutch in my car and it's been trouble free. Misalignment will lead to premature failure. I've also seen the shaft length adjusted improperly. If's possible to adjust it so that to much of the rod is extended past the clevis at the pedal. If this is the case when the pedal is depressed it hits the rod and can bend it. A bent shaft will cause the misalignment. is the fluid in the reservoir clear or dirty and gritty?

It's been awhile since I had a McLeod set up. It was nothing but trouble. I think the supplier of the external set up might be Mike Forte. He's in MA and pretty sharp.
