Brakes binding

Here is an interesting non-CBX brake issue.
I did a brake line repair on my sidecar rig. The two rear brakes are difficult to bleed and I thought it was O.K., although the pedal still felt a little spongy. During a test ride, the brakes started to bind and I stalled the engine. I got the rig back home and did not know what else to do other than bleeding the brakes again. It turned out, the rear brake line on the bike routes very close to the left exhaust and the air in the line heated up and expanded enough to create pressure in the cylinder and made the brake bind.

Mike, With the brake lever in the rest position, wouldn't the expansion be relieved through the compensating port into the reservoir ?? Unless the reservoir was hydraulically locked ( IE overfilled) ??

I think so, Larry.

After a while the brakes loosened up. This is how I was able to get home, I think.
