I was able to loosen the pedal with some WD-40 and a rubber mallet. Cleaned it as much as possible. Couldn't get it off of the frame because of the clutch cable connection but I got it far enough to clean it up and lube it good. Got it back on and the spring attached properly. Replaced the cotter pin and reattached it to the master cylinder clevis pin. Waiting on the new flange bolts to secure the master cylinder.

You will find that the the rear brake pedal will be 150% better with the lube on the pivot point. As per wingadmin, I hope you used marine grade grease, and a stainless steel cotter pin. I just did this job on my 1983 aspencade, and what a difference on my rear brake. Good for another 36 years!!!

I did not use marine grade grease, but it's not too late. As far as the metal type on the cotter pin, I'm not sure but I will check.

Cranked it today and let it run till it got hot. The radiator fan kicked on slightly before the red line. Yea! Something I won't have to replace. $$$

Also, the box of cotter pins does not specify the type of metal. Got it from Harbor Freight. Assorted kit.

By the time it takes to rust that pin. The joint will need to be cleaned again.

Sounds like you are making progress.

Regarding the speedometer, I was testing it out today. With the key on, engine off, should the speedometer register if I spin the front wheel? It didn't move when I did that. I pulled the cable out of both ends and the sensor is turning at the wheel and the cable is spinning at the speedometer end. Am I missing something? I've read some of the discussions about the speedometer but nothing seems to describe the issue that I'm having. Any suggestions?

Thank you.

With my 82 GL1100I, if I rotate the wheel with the cable unattached at the gauge, the cable turns counter-clockwise. When connected to the gauge, if watching the trip odometer VERY closely I can see it has moved slightly after a dozen or so wheel rotations. Make sure the top square end of the cable is engaging into the gauge, also you can use a small screwdriver into the gauge and rotate it counter-clockwise to just check the gauge and it should turn very freely. You might see very slight needle movement with the screwdriver. Using a drill will definitely show needle movement.

I have rebuilt the rear master cylinder and it is leaking around the boot. On top of that, while trying to bleed the brakes, I found a blockage in the line between the rear caliper banjo bolt and the bracket that holds the adapter where it changes from soft hose to hard metal line. I've tried using the mity vac to get any debris out as well as putting my air compressor hose to it. Nothing is working. So I need to know what that part is called so that I can replace it. Also, I'm going to buy another rear master cylinder. Hoping that I can find one that is in decent shape. Any suggestions??

I was able to clear the blockage. I had some leftover garage door cable that I used to repair my shop garage door. It was just the right size to stick in the hole at one end. I also had to use a small Allen wrench to unclog the end. Once that was broken up, I stuck the cable in all the way to the other end. Sprayed some brake cleaner in it, reamed it, then washed it out with wd-40. Then I attached my air gun to it and it blew air out the other end. I reconnected it and was able to bleed the rear brake. However, the master cylinder is still leaking from the boot as well as from the connection at the top where it connects to the hard brake line.

Dude, keep going with it. I've done a lot of work to my 80' interstate, and I'm glad i decided to buy it. Keep in mind that this is the first bike I've EVER worked on. I am very proud of my work so far.



This is how it sounds as of right now, haven't synced the yet.

Thank you. I have no intention of stopping. I have not synced my carbs yet. I also need to adjust my idle. I am in the brake bleeding process now and I have discovered a second blockage in the line going to the front right caliper. I had a blockage in the rear caliper brake line but I was able to clear it. Hopefully, I will be able to locate a rear brake master cylinder because it needs to be replaced. After that, I plan on replacing the timing belts. I thought that my buddy did it, but he told me that he didn't because he thought that they looked fine. I bought them, so I'm going to replace them. After that, I'm going to sync the carbs, replace the tires and mufflers and I'll be ready to go.

Thanks chewy. I spotted that also on Ebay. I contacted the seller but they have not responded. It's been 2 days now.

Did you know or did I miss the part about you also knew the rear master cylinder is one of a kind on the 83 because of the linked brake system? When you press on the rear brake pedal a front rotor also applies braking.The front brake lever applies pressure to the left front only. Did you know about the little hole in the master cylinder that clogs up? Try using OEM parts and try a rebuild again on you master cylinder.There is a how too on the master cylinder. These master cylinders are a little bit hard to find. Oh there is only one rear rotor that fits the 83 and that is a 83. A softer pad on the rear instead of those super race pads is best. Wear out the pads instead of the rotor. Yes I know more changes but it beats a new price of a rotor. Stay at it you are doing a good job.

Nice. So you think the leak could be a clog? Well that sounds a lot more fixable than finding the unicorn master cylinder without having to buy a parts bike, which is not completely off the table just yet. Thanks. That will give me something to tear apart this weekend. I used a rebuild kit for the master cylinder. As a matter of fact, it was one of the first things that I did to the bike when tearing it down.

Before you disassemble operate the rear brake and check to see if the right front is also working. If so this should mean the little hole in the master cylinder is a ok. Did you read the how to rebuild master cylinder under manuals? Get the cyl apart and let us know whats up. Carry on...

***UPDATE*** I disassembled the master cylinder twice. Cleaned it thoroughly. Blew compressed air through every orifice. Cleaned up the crud on the plunger that attaches to the clevis. Reassembled and it leaked worse than before. Realized when I took it apart the 2nd time that I had placed the interior plunger in backwards. Fixed that. Reassembled. I was having an extremely hard time getting the circlip out the 2nd time I disassembled it and thought: maybe I put the circlip in backwards or it didn't seat properly. Either way, I flipped it over and reinserted it and made triple sure that it was seated in the channel. Reattached it to the lines and bleed the rear brakes with no drips at all!! Yea!! However, I am still unable to bleed the front right brake. It builds pressure with the mity-vac but slowly decreases without depressing the foot pedal. I think there may be a blockage somewhere in the line leading to the separator which, if I remember correctly, is located just near the center stand. Any ideas on that before I tear into that mess? Of course, I will have to drain the brake fluid before I disassemble those lines. I'll have to buy more brake fluid because I've gone through 3 bottles bleeding front left and rear brakes.

Keep in mind that mine is an 80 model, both calipers run by the mc. Bike on side stand, wheel all the way to the left. I used an old gear oil bottle with a piece of clear hose attached. I also put teflon tape on the bleeder. I filled the bottle with brake fluid, and forced it into the bleeder on the caliper until I saw it come up to the mc. I also had my girlfriends 14 year old daughter there as my gopher. Good luck.

Found the blockage and removed it using a small Allen wrench and some brake cleaner, small strand cable, and thin solder wire for the banjo bolt end. Used compressed air to finally clear it and then used the Mity-Vac to suck the crud out by filling an empty pill bottle with brake cleaner and sucking it through the brake line. It took me almost 3 hours of persistence to clear the blockage. Here are pics of the connections where the blockages were at.

I'm glad you were able to get it cleared, and that the lines are good. I had to replace my fro t lines to the tune of 138 bucks.

On another note, I've passed the written test. Now on to the riding portion.

***UPDATE*** I replaced both timing belts last night. Filling her back up with antifreeze and then on to the crank test. Fingers crossed...
****UPDATE #2**** It worked fine. Seemed to run better than before, but my carbs still need to be synchronized. That's next on my list. After that, its tires and maybe mufflers. I kinda like the sound of the half pipes, but neighbors and local police may not.... :)
