Since it has been getting warmer I've been noticing some strange behavior in my front brake lever. In the morning I have about 3/8" to 1/2" of "play" in the lever. But by noon, I have almost no play in the lever, the other day when it was very sunny and 103 I think I actually had negative play. That is, I think the front brake was partially engaged. As I went to pull away after starting up and it did a little dive before it took off with a little bit of drag.

Normally when it was getting no play it would get real touchy, barely tapping the front lever would over engage the front brakes.

As I get air moving, the lever relaxes a bit.

Anyone else have this happen, I did a search and didn't see anyone reporting this. The brakes are good other wise when the temps are normal. Rear brake seems unaffected.

It's 101 here today, but it gets near 100 everyday here in Atlanta and I've never noticed it having any effect on my brakes. I wonder if someone put the wrong type of brake fluid in there, or maybe there is some air in the system.

I was on that same path, maybe a fluid that is more susceptible to heat. Although I can't imagine it was ever acceptable to have fluid that could expand due to heat.

Air seems like another good possibility but I don't get the squishy sensation in the lever like I'm compressing air. Maybe water?

This scooter has been wrecked so it is a likely candidate for having had the lines open. It only had 4400 miles on it when I got it in April. It has closer to 8000 miles now.

Or it may be an over-filled situation too.

As it gets warmer it keeps getting worse. Today as I took off from a light the back end came up like I had the front brake on. I went to park and even with the engine off I could feel appreciable drag trying to walk it back into a stall.

I think I'll start by removing some fluid from the reservoir. I can see that it is over filled. If that doesn't fix it I'll try bleeding the line.
