Rear brake pops off.

Sooo.. on my yz250 I have a problem with my rear brake. I thought I had it on the right way but eventually my rear brake lever will come off and not work. I've went through my manual and tried to find videos of how it looks but no luck.

Here is a pic of what it looks like

Check a parts schematic on any oem part seller's website.

The bottom nut of the three should be tightened against the bottom u shaped arm. Without this in place and tight , the master cylinder plunger will turn and thus come loose.
Also one nut should be under the U shaped arm as well.

The two nuts don't look right...
Must have posted as paw posted +1 for paw's post.

Yup. Just checked my CR. It only has one nut and it is up against the clevis, not up by the cylinder.

Thanks Paw will try it soon. I thought it went inside the u shaped arm but when I tried to get the nut back on I had know idea how I could tighten it so I just assumed both go together.

Put one inside the clevis (u shaped arm) and twist the clevis to get the brake level at the height you want, then tighten the other nut against the top of the clevis to lock it in place.
