rear brake problem

Postby Pilotgoldwing » Mon Sep 09, 2013 6:33 pm



Here's a new thread. I'm still searching for all the bugs in my "new to me" '84 GL122 Aspencade. It sat in a garage for a few years before I got it. When I was putting it on the trailer both front and rear brakes seemed to work correctly. However, once I got it started and went for my first short ride I noticed the smell of brakes. I attributed it to trucks in the area until I was close to home and notices that she was pulling harder and harder and when I pulled the clutch she rolled to a quick stop. I traveled the last 1/2 mile slowly in first gear to my garage and put her up on the center stand. I waited til today to check her out after the brakes had cooled and the rear wheel still have a fair amount of brakes being applied with the pedal up. I checked the fluid and the level was right in the middle of the range. Next, after repositioning the left side saddle bag, I cracked the bleeder and a little spurt of fluid came out. With that I tightened the bleeder back up and the rear wheel turned freely. I went ahead and bled the rear brakes a few cycles and only got what appeared to be clean clear brake fluid out. Once that was done I cycled the rear brakes a LOT and operated normally each time. Certain that I had the problem licked I set out on another short ride only to have the same thing happen again. The bike is now back on the center stand and the rear wheel has a good amount of brakes currently applied with the brake pedal in the normal position. Any thoughts?

Your going to need to rebuild your rear caliper as it is hanging up,this is due to it setting for along time. Get a rebuild kit and follow the How to s on this site (easy peasy ) ------------------------------Hal

Thanks Hal, I have a kit on order thinking it might be that. I also on the last ride noticed that the bike wouldn't accelerate beyond 3000 rpm in OD. Continuing to roll on the throttle didn't help at all but just made it run rougher. In lower gears it will run the RPM up much higher and in Neutral it will run way up. I'm thinking I need the carbs cleaned, correct?

If you have not tried it yet I would run a bunch of seafoam thru your tank for a couple of tanks it should help alot.-------------Hal

OrHal,
I'm Not Familiar With Seafoam. Is It Cleaner To Rinse The Tank Out With OR Additive To Run Through The Carbs?

Its the best thing you could get for your fuel system it will dissolve any gunk in your fuel lines and carbs. You can find it at any auto parts store or a Walmart. I buy it by the gallon when its on sale,and if you want to you can add some to your oil and take a short ride no doggin it the come back and change your oil you will not believe the gunk that it will break up. I like others use it in every other tank or so. It also works good as a winterize r for your gas over the winter.

If the rear caliper is hung up like you describe, try cracking the bleed nipple to let pressure out. If that fixes the problem, then the problem is not the caliper, it is a blocked return port in the master cylinder.

The return port WingAdmin was talking about is a small hole in the bowel you will find some articles of how to clean it out with a small piece of wire from a wire brush or something along those lines.------Hal

You'll see pictures of me cleaning out the rear master return port on my 1100 starting at step 17 here: How to rebuild your rear master cylinder

Thanks guys, the return port was the issue. I'm slowly getting the bugs worked out and as soon as I can get the Alt conversion done it will be time to hit the open road.
