Just looking around quickly this morning, it kind of looks like the 80-81 only had the single piston and the 82-83 have the dual. The pads for the 80-81 only have a little tab out the back, and the 82-83 have 2 holes for the pins.

Not sure if that is helpful or not. I'm new to wings, so hopefully someone more experienced can chime in and confirm, or set us both straight!

Good luck!

Those are the ones! You would think the shop lists would have it right for 1980! LOL. I had the same issue buying a new battery for my 1980 Yamaha 650 Maxim on Saturday. Up here in Canada we have an iconic chain called Canadian Tire. They have the wrong size battery listed for my little bike. Way too big to squeeze into the frame! I got an apology but no mention of the parts desk guy committing to contacting head office to request a correction.

From now on I take the old parts in when I shop for replacements.

Oh crap. I bought the pads a month or two ago and I just remembered the shop lady asking if I had single or dual brakes. I said dual because the Wing has dual brakes up front. Maybe she was referring to the brake pistons! Might have been a rookie move on my part! Aargh

Anyone want to volunteer bringing them back to the shop for me? ;)

Thanks by the way Chevy. You were a big help! I love this website Admin! My Harley buddy across the street is jealous. He finds most online resources are paid sites. Chevy, is there a Harley Site equivalent to this one where he can go to learn how to do his weekly repairs to his 1999 Sporty?

No problem on the help!! It's nice to be able to give some help back on here!

Whenever possible I try to bring the old parts with, or at least look at them good, then check the parts before leaving the store. LOL Makes it much easier.

Hopefully they don't give you too much guff returning them after this amount of time!

I haven't found a Harley site that is near this informative, nor as nice of people. Most of the guys on the Harley sites are kind of jerks,there are some good helpful people too, but for the most part not real nice. HDforums.com seems to be the least rude, and is free for the most part. A service manual has been my best friend on my bike. Whenever I have issue, it seems to be easier to look it up in there, and just get after it myself.

Right as I clicked off of the message I noticed you have an Interstate. That may matter on the brakes too. Would be a worthy question to avoid more down time!

I bought front brake pads for my 1980 GL1100 and followed the wonderfully precise method for removing the front wheel in anticipation of taking off the greasy pads and cleaning up the leaked fork oil. Then before putting on the new pads I planned to replace the fork seals using another DIY from your Site. Really helpful for this newbie until I notice that my front brakes only have one piston each! The pads are a completely different shape than what I bought.

I am sure the shop will take them back but what gives? The ownership papers say 1980 so could these be the wrong brakes? Help! I am sitting in my garage staring at a lovely bike that really wants to start rolling but can't.
1980 and 1981 GL1100's had single piston front calipers; I suspect you were sold the incorrect pads.

Ran into the dreaded stuck brake retainer pin situation, had to purchase a punch pin to knock it thru......got it 3/4 of the way thru and the taper on my punch wouldn't pass thru the 1st retainer hole enough to push the pin all the way thru the caliper.

Off to sears to purchase another push pin set that is extra long, it didn't hurt to blast the pins from every angle with PB blaster penetrating oil. What a nightmare.

As per windadmin advice when the pins are out I will be putting a drill bit thru to just open up the holes a tad, enough to allow the pins to push thru by hand with some resistance,

What size drill bit did you use Wingadmin?

Best,

I can't respond on what size drill bit to use as I didn't do that trick. However I did put the retaining pins in my cordless drill, wrapped some 220 sandpaper around them and gave them a good polishing. That seemed to help make subsequent removals easier.

Good luck.

That worked out where you could put the retaining pin back in the caliper by hand without coercion via a hammer, etc. ?

i had that same problem removing the pins from my 83's calipers. once i got them out i took emery cloth, got them nice and clean and used this.......http://shop.advanceautoparts.com/p/perm ... brake+lube on all the brake caliper hardware especially the pins. its also good to put it on the back side of the pads as it stops the dreaded "break squeal".

Polishing the retaining pins as I did (emery cloth would also work well as noted above) made it much better, but not totally "tools free". Once you're through the brake pads you have extra friction regardless. This then required a couple of gentle taps with a hammer to finish driving them through. I had considered using brake lube on the pins but have not tried it. Likely to next time I the brakes.

i've always used disk brake lube on every brake job i did when i was working as a tech. even to this day i always use it. it helps the pads slide on the retainer pins easier and for removal of the pins for when they have to be taken apart on the caliper the next time, and on vehicles with drum brakes in the rear, i use white lithium grease on the backing plate, star wheel adjuster and the exposed emergency brake cable because its water and heat resistant.

Got the pins out with a 3/16 carbon extra long push pin with a flat tip. Gotta say that when those pins came out I was beside myself. The emery paper cleaned the pins right up.

Thank You!!!!!!

your welcome. emery cloth is also good for cleaning ground wires and ground to frame connections, and battery cables and posts.

You say, "Apply high-temperature brake lubricant to the pivot bolt." can I also use the same lubricant on the pins for easier removal next time?

this would be a good product to use...............http://www.oreillyauto.com/site/c/detai ... brake+lube along with this.............http://www.oreillyauto.com/site/c/detai ... brake+lube use just enough, a thin layer to coat the parts without using too much.

What are your thoughts on just disconnecting the break line and removing the caliper from the bike to remove the pins? Priming the breaks is no big deal, A?

Re: How to replace your front brake pads

Post by roadwanderer2 » Sun Oct 23, 2016 7:16 am

well, you could do that also. but what i used to use when i was an auto tech was called a "brake line clamp". it was used to put onto the rubber brake line and gently clamp it shut so the brake fluid wouldn't leak out once the caliper was removed. for some reason i cant find one at any of the auto parts stores i have saved onto my computer. it was more of a "specialty tool" that the tool trucks, IE: Mack, Matco, Snap-on or Napa that came around to our shop sold.

you could also use a pair of needle nose vice grips to gently squeeze the line shut with so you dont loose any brake fluid before you remove the caliper. once you reinstall the caliper, brake bleeding would be at a minimum. the only fluid lost will be from the caliper itself.

remember, once you break that banjo bolt or bleeder nut loose, you'll have air in the system. the more simpler way to do it would be to reinstall everything once you've rebuilt the caliper and "gravity bleed" the system. on a bike it will take a while to do. fill the front reservoir with brake fluid, open the bleeder nut and allow the brake fluid to slowly come out of the bleeder screw keeping an eye on the amount of fluid in the reservoir. once its "gravity bled", close the bleeder screw, refill the master cylinder and bleed as needed.

Going to attempt to change my front brakes soon. I noticed that the brake line was removed in the tutorial. Is that required or will it make changing the pads easier? If I do remove the brake line what do i have to do to reconnect it? Prime the brakes? I want to replace the fluid anyway. If I take off the brake line will fluid pour out? Is the brake line torqued?

You don't need to remove the front brake line. The reason the pictures show it removed as I was doing several other things at the same time (I think I was rebuilding the caliper, if memory serves).

Just make sure that when you retract the pistons, that your bleed valve is open, so it doesn't push the grungy, filthy contaminated fluid back up into your master cylinder, where it will block the return hole. It will squirt out, so put a hose over the bleed nipple and the other end of the hose in a bottle or something.
