The image below indicates that in order to adjust the breaking pressure from 19x20 to 19x18 is by simply rotating the adjuster screw by 180 degrees. Now lets say if I messed around with the adjuster screw but instead of going back and forth 180 degrees, I accidentally rotated it 360 degrees clockwise (I don't remember exactly how many times I did that). Would that unscrew something within the piston and cause my MC to fail? Please share your thoughts. Thank you

2 questions in order to answer your question.

Do you still have brake pressure?

And is there any brake fluid leaking from the screw or anywhere around any of the brake lines or master cylinder?

No pressure loss or leakage anywhere...I looked at the rebuild kits and they are held in with c-clamps...But I still wanted to get a second opinion from you guys...

the stock setup on my FZ09 has a adjustable setting on the front brake lever, I guess it suppose to make the front brake lever feel tighter, but on mine, when I adjust it, it gets looser.

I only leave it on one setting, the setting that feels like it has the less travel of the front brake lever.

IMO, it doesnt really do anything.

The stock setup only moves the level closer or further from the bars

I would try unscrewing it a few turns to see if the screw gets elevated in the hole. I would imagine that it has an eccentric on it that alternates between the two settings, in which case you can turn it as often as you like and it won't harm the MC.

of course there's the distinct possibility that I don't know what the hell i'm talking about, so take that into consideration.

I have that Brembo MC on another bike, it does have 2 positions with a "click" at each. I would say back it out till it looks like the same depth as the picture you posted, click it into the setting you want and you should be good to go.

The adjustment doesn't change anything with the piston or pushrod (exception of the pushrod angle). All you're doing is rotating a leverage slot on the lever that the pushrod sits in, you should be able to spin it for days...

Yup you guys were right.I just checked.Only the adjuster spins.The piston/pushrod stays put.Thank you all
