Stuck rear brake pedal

Post by BigDee » Wed Jan 02, 2013 11:26 am



I am new to wings. Got a sweet '81 gl1100 interstate for $1800. Needed carb work which is just about completed. But now I've found the rear brake pedal is stuck. I took the connections off and they activate the brakes. Is there a grease during on the pedal? I couldn't see or feel one. How can I get it loose?

I meant is there a grease fitting, not during. Crazy phones!

It is quite common for the pivot point to rust up on these bikes. Can you pull the brake pedal back up withyour hand? If so that will make it easier to fix. There is a cotter pin and washer that you need to remove and slide off the pedal , clean up the rust and grease the pivot, reassemble and you should be good to go again. As far as I know there is no grease fitting 8-)

No, no grease fitting, although I know of someone who fitted one to it.

Like he said, pull that pedal off, use some fine grit sandpaper to clean the rust off the pivot pin and the inside of the pedal. Pack it up with some good quality marine grease, put it back together, and it should be good for another 20 years or so.

I was able to shoot some white lithium grease into the gap and work it back and forth enough that now it is free. Thanks, guys! You're awesome!

I've had this problem for a few years, and finding the pedal stuck every spring, I find myself get the spray lube and wiggling the pedal free. I wanted to try greasing but found the pivot washer and cotter pin inaccessible for me so it was back to the spray lube. I took a couple pictures for the record.

Here's the clevis pin that attaches the pedal to the rear brake master cylinder :


Easy to get to but I'd want to have a new cotter pin handy as it is not too beefy.

Here's the washer and cotter pin that hold the pedal on at the pivot point:


I'm waiting until I have the bike up in the air or until I lose 30 pounds before I try to get up in there and remove that pin.
I think I'll start looking for a jack :o :lol:

Definitely have a new replacement cotter pin, and make sure it is stainless - you don't want it rusting away and you suddenly realizing you have no brakes.

Got a proper jack and did the job.


Got the cotter pin out with no more than the usual hassle. What did happen was that the arm of the brake pedal hit the clutch cable before the pedal was all the way off:




Rather than force anything I worked with it in the position that it was in since the pedal was nearly completely off. Cleaned it up with some 600 grit and steel wool then applied some of the grease that is used on caliper pins. Lots better now.

Rear brake is starting to squeal and pedal not returning. I'll have a go at this this week.

Had to do this with my Aspencade a couple of weeks ago. As much as I love living near the ocean, the salt air really takes its toll sometimes. For some reason, my Interstate never had this problem.

Finished up last night! Pivots like new again! The spring wasn't nearly as hard to get back on as I thought it would be, which was the most dis concerning part working in the cramped space. I found the SAE equivalent cotter pin at Canadian Tire for the smaller 1.6mm pin at the master cylinder linkage, but couldn't find an appropriate one for the larger one so I put in a 3/32 x 2" for now until I order the part now, along with some bleeder valves

Anyone have any recommendations for the type of grease to use on the pedal pivot? Last year I used the grease for the caliper slide pins and it didn't hold up too well.

Marine grease, good, thick, sticky stuff, as much as you can pack in there. You basically want to keep air and moisture out.

I only had some high temp grease kicking around. Will update next year or any changes

I was surprised that my last attempt at lubricating the brake pedal lasted only a year so i decided to be a little more thorough this time. Loaded up with marine grease, thanks WingAdmin:


I needed to remove the clutch cable in order to have room to slide the pedal off the pivot, but ran into this:


Somehow the gap used to allow the cable to be slid into the bracket had been pinched closed so that it was not wide enough to allow the cable to slide out. I was afraid of damaging the cable so I didn't try to spread the gap. I loosened the cable and slid the pedal over as far as it would go. Is that gap normally pinched closed like that?

My rear brake pedal is stuck too and I plan on following the instructions above. However I have a couple questions - do I have to take the pipes off or the rear wheel off to do this?

No. Most of job is done from underneath the bike at the point where the pedal pivots. I needed to jack the bike up to do it. If you jack the bike up use straps to secure the bike to the jack. Here's some info on doing that: viewtopic.php?f=11&t=1661

What is the size of the clevis pin that connects the pedal to the rear cylinder? I took it off and I just can't seem to find it. I will check the local auto shops for it.

Looks to me like you can just unscrew the clevis saddle, part #16 here:


You could then take it with you to the auto shops. I would just buy two or three and then return the ones I don't use. Here's another pic that shows the clevis pin, part #6. The cotter pin for the clevis pin is part #19:


As I recall, I had to use a small hacksaw to reduce the size of the cotter pin that sits behind the washer and holds the pedal onto the pivot, part #21. I did so in order to reduce the distance I had to lift the pin so that it would clear the pivot. Doing so also made it easier to straighten out the pin before lifting it out of the pivot. I may have put too long of a pin in the last time I did the job. Whatever the case may have been, it was a real pain to get it out the last time I tried.

Thanks for the info. I went to home depot and picked up a couple clevis pins. Hopefully one of them fits.

Don't forget WingAdmin admonition to use a stainless steel cotter pin for that clevis pin.

Yep, got stainless steel cotter pins. :D
