Stuck rear brake pedal

Postby 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
