Front master cylinder substitute

Post by lazeebum »



I rebuilt the front master cylinder on my 98 goldwing, but it still doesn't work properly after bleeding. It holds a good pedal for a few stops and then it goes to the bars.
My question is, is there a good aftermarket replacement?

Probably your biggest issue will be getting one that will allow both the cruise & brake light switches to mount on them.

I just got a descent looking item off Ebay.

I also went with an 1800 unit because it has the adjustable lever.

Did you buy a new, or used one? And does it work with the 1500's cruise? I actually forgot about the cruise.

It was not new. I picked one that look like it might be in good shape, disassemble and cleaned it. I was prepared to get a rebuild kit for it, but decided that it didn't need one. It wouldn't be a mistake to order a kit, if you go this route. The 1800 have both silver and black levers.

Yes, it also has switches for the brake light and cruise shut down.

So the 1800 setup fits a 1500?
What about the clutch, is that the same as well?

I have that master cylinder from a 95 Wing that I am parting out.

Yes, the clutch is interchangeable also. I wanted adjustable levers on both, so i went with the 1800s and they work fine.

Wish I knew that when I had my 1500, I like the 1800 levers so much better.

I failed to mention that the ones I used were from the first series of 1800s. Looking at the later series, I don't see much/any differences. You also have to be cautious of the aftermarket ones. The only ones I'd use are OEM ones.

Thanks for the responses. I'll get it sorted one way or another.
