RE: Rear Brake Fade? - suhawk305 - 07-18-2018
I read all of your opinions and suggestions with interest. SportsterDoc - at the rear brake failure, I could not smell anything like the brake pads were hot. I had to ride a few miles to find a safe place to easily pull over. By the time I inspected the brakes, all parts were cool. The rotor color looks normal like the front rotors.
That bring me popgun’s suggestion to flush the hydraulics. I think this is definitely worth the effort, needs to be done anyway. Like Townie, I used the same simple technique to bleed the brake lines on automobiles. I assume I can do the same on the CB, both brake lines and clutch.

Yes, same technique.

The rotor would have cooled quickly, while moving.
If not discolored and no lateral run-out, then likely no harm to the rotor, if pads were applied.

I would flush the brake fluid just because of your scenario, which sounds a lot like an overheat situation. That fluid is used

Speed bleeders and a vacuum bleeder with your compressor :piece of cake !

I'd love to see a pic or explanation of that cake

Well, it would be moist!

Update: I started by bleeding/flushing the clutch fluid the the old pumping, open/close bleeding screw, and the fluid bleeding stopped during the process. I must have accidentally introduced too much air in the clutch system. I got the shop manual out and saw that a vacuum bleeding tool was recommended. I got one from Harbor Freight that works with my compressor, as Houtman suggested. I was able to suck the air out and complete the flushing job.
I next did the the rear and front brakes, and it appeared that some air bubbles came out during the flush.
Took a short test drive and all systems worked.
I have to find out what “speed bleeders” are for the next time.

Just installed 4 of these on my bike. Flushed and put new fluid in both brakes and clutch. It’s a one person operation and very easy. If you use search on the forum you’ll find several threads on speed bleeders.
