TOUCHY SUBJECT: DE-LINKING

Post by rider1939 »



Hi All,

Yes, this is a touchy subject to some, but I was wondering if anybody has done this, and if so, can you let me know how it worked out. My issue is the two different size calipers and if that caused a problem.

I can speculate, "till the cows come home", but I'd love some first hand knowledge.

Thanks

Josh

Looks like it's been awhile since you posted this question without any replies so I'll take a stab.

DON'T DO IT! Your motorcycle will explode and the purists will send search parties to pick up what's left of your carcass to bury the parts on separate continents to be sure you never rise in the future to commit such an atrocity ever again. Even if you don't wreck you'll suffer from male pattern baldness, erectile dysfunction and several other maladies which have yet to be recognized by modern science. Secret ninja warrior bands will torment your family for at least seven generations and every year on the anniversary of you "Successfully" completing the project the re-animated corpse of Soichiro Honda will rise from the grave in an attempt to lay all of humanity to waste.

All the previously described reasons I just mentioned are why I did it on my '83 1100, that and the fact it was cheaper and easier to de-link. Mine too has different sized caliper pistons on each side of the front wheel and to tell you the truth, I can't feel any difference when the brakes are applied. It stops faster than it did with them not working correctly and that's fine by me! Have not noticed and difference in wear on the disks or pads and I'm not going to sweat it from here out unless one of the warnings not to do it as already outlined actually happens.
I'm selling good clean fresh hay. If you want some that's already passed through the horse, that comes a little cheaper!

Thanks LAB3,

I'm already suffering from several of those maladies, and I haven't even started with the de-linking. I look forward to the challenge of avoiding the rest of them.

I, like a few others, don't like the idea of trying to control this monster in questionable traction situations. I've had decades of running none linked brakes, I de-linked my ABS Concours, which turned out fine. This my first Goldwing, I do have another, but it's never seen the road with me on it.

I'll give my family a heads up about the coming repercussions.

Thanks Again ! ! ! I think.

I used to have a Honda ST1100.
Brakes were not linked, and the rear wheel brake would lock up in a heart beat....

It took a lot of practice to get the "feel for braking" back, after I lost my GL1500 to a semi truck.
I already owned the ST1100 which I had bought so that family/friends would have a ride.

rode that thing for a couple of years, never so glad to get shed of a m/c in my life.
Not designed for senior citizens, it killed my back on long rides.

found a 2002 gl1800 and of course, Linked Brakes, never once had a wheel lock up, and it would stop on a "proverbial dime"

already got most of the other maladies, too late to worry about them now.... at 78... :lol:

Never made a full post on how I got to this point since it was more a comedy of errors which led me to this point as opposed to a clear cut plan. The set-up I'm running now is a set of generic eBay sourced master cylinders both front and rear, both of which can be gotten for less than the price of a master cylinder rebuild kit. The rear master required me to cobble up a bracket to mount the master cylinder at the proper angle to accommodate the direction of travel of the plunger, easily done with a piece of scrap metal, a hacksaw and a drill. The front master is connected to both hoses via a longer banjo bolt that allows you to put both lines on the same fitting directly on the master cylinder.

If you're looking to enhance your braking this probably isn't the way to do it! The way I did it has more to do with my lack of a garage, permanent place to live and and having parts delivered to do things "The right way". The Chinese Penguin AIDS put a damper on my lifestyle this summer but generally speaking I camp out six months of the year with repairs taking place where and when they need to occur. Sure, it's nice have them un-linked when you're going off road and it's best to not use your fronts, for my use and situation un-linking is what made the most sense, your results my vary. Do this at your own risk, in my case that risk is pretty minimal.

thanks mr lab3. you kept it quite simple with the great idea of longer banjo bolt. LOL on the disclaimers! a necessary evil these days.

Just to clarify, it's not just a longer banjo bolt, it also has another set of holes for the fluid to flow through as seen here: https://www.ebay.com/itm/143822647646

thanks. i assumed it would have to be "double" cross drilled. where did you source the hose for the right side caliper? my muscle memory has been trained forever to feather, drag the rear and use the front for stopping. i am too old to try and relearn. i also dont want to become reliant on such a linked system and then ride other motorcycles that are normal. when i was doing initial maintenance after buying this used bike, i found the front brake almost non functional. one piston was covered in crud and the other was stuck from not being used. previous owner had become so reliant on the link system that he had never used the front brake lever.

Speculation on my part, but I'd bet you'd find linked brakes ARE normal these days on just about ANY bike bigger than a dirt scrambler..... (or "Custom" Hardleys) :lol:

That particular one was made on the spot at an auto parts store up in Illinois, another case where eBay will be your friend price wise when looking for a specific length hose. Many auto and farm type stores can make a custom brake line for you although it gets a little tougher when you want stainless steel.

was hoping you would tell me a particular application from a salvage yd. as there are no such industrial supply type places (nor farm supply with hose mandrels that small) around here. i could call around but no specs. was that auto parts store NAPA by chance?

Remember, you're breaking the rules here and will need to figure some things out as opposed to following a set of well established directions. Being in a rural area, ordering a line off eBay is probably the easiest way to get what you want, there's plenty of folks on there selling lines in different lengths. One thing to keep in mind, they usually spec the lengths in centimetres as opposed to English lengths, this will require you to use the metric system. Contrary to many common myths, learning to use the metric system won't make you a socialist, not right away anyhow.

lol, learned metric in jr high. that was before common core and when public school taught the three R's. love the pun in your first sentence but you misspelled braking. dry humor goes a long way with us southerners.

Hi there,
I did it because I have a side car and need to use the front only if needed...
At the rear master cylinder, I moved the rear brake line to what was the front line for a direct feed from the pedal. What was the port for the rear brake now feed the side car.
At the front, I install a double banjo and connected a custom SS line to the left side. I also replaced the rubber line by a SS one for the right side. I wasn't happy with the feel on the front lever, ie: Too long of a stroke for my liking. So I replaced the front master cylinder with one from an 1800. Look at the volume needed for the calipers and it is now a very good feel on the front end. It is a straight exchange with the same brake switch... If I remember correctly, you go from a 14mm to a 16mm master cylinder. No major change regarding the pressure to apply at the lever. May be a tad harder but I like it.
The front brake is now MUCH more efficient so take it easy at first, the 1500's don't have ABS :shock:
My front suspensions were also rebuilt including the anti dive system. I DO have the proper springs to take care of the side car. So no bottoming out to report.
So long story short, it takes a bit more work IMO to make it safe, than just adding a double banjo and a new line!
As a disclaimer, this is what I did on MY bike... For info only :D and would dare tell you what to do!!!

thank you mr elmo! seems you have a sense of humor also! it also is obvious you know how to drive and fly a sidecar! very few people know how to manipulate the brakes to drive a sidecar. and thak you for that information on the 1800 master cylinder!
Merry Christmas and best wishes to you and your family!

I did mine and it's the best! I rely on the front for most braking situations, using the rear only if I need more stopping power. Under most circumstances the front is now perfect. So the foot stays relaxed on the peg and the hand takes the chore with ease. With the linked system the front was pathetic by itself, not that now being unlinked they're powerful by any means. But, that said, for my style of riding having all my front power controlled at the lever is best.

The only thing I'd like to ad is the cheap brake lines from eBay are stiff and could be a problem especially for the front end. I'm rebuilding a 78 KZ750b. It'll only come out on nice days so I ordered the cheap colored SS brake lines to dress it up a bit. Bad idea. I went to my local logging supply and they built me some lines that can be twisted into a pretzel. I'm happy.

Yeah, I've seen those and had one on one of my former bikes. Be sure to choose braided stainless steel!

Delinked my brakes on my 83 Interstate. Rebuilt all the calibers, picked up a older front crossover block on eBay and bought custom brake lines from Galfers in California, quality brake lines. End result, is they work great.
