GL1100 rear master cylinder upgrade
 
A lot of times the rear master cyl on old bikes is bad and unrepairable and you can't get a new one. I have found a solution. I bought one for a Valkyrie off eBay and made it fit the 1100. This was done with the fuel tank out, but should not be a problem with it in place.

The Valk MC has bolt holes already the proper size to tap to 8x1.25 for the original bolts.

I then mounted it to the frame in the OE rear bolt hole and the upper hole in the MC with a spacer 3/8" long w/8mm hole.

I then made a bracket of 1/4 x 3/4 steel with 8mm holes 1" C to C to fit from the OE front hole to the lower hole in the MC.

Bracket mounted to MC with 8x1.25 allen head screw.

Mounted to frame with OE bolts, a nut is used on the back side of the bracket, could have tapped threads in it but didn't think of it in time.

2 washers were used to space the bracket out from the frame for alignment.

Had to work up a little slack in the brake line to get it to curve around to clear the swing arm. A new SS braided line would be a good thing.

The OE supply hose is too short. You will have to get a 3/8 hose compatible with brake fluid, 3/8 is a little tight on the OE reservoir and loose on the MC fitting but will work. Didn't even have to adjust the rod length for pedal height.

about half of the pictures have bad links, something is askew linking to your photobucket account.

I went direct to your page at
http://s127.photobucket.com/user/bldontp/library/1100 project?sort=3&page=
and the pictures are good, they just don't show up for me in your post.

The pictures at #s 1, 2, 3, 5, say "Photo not found"

I would fix it, if I knew which picture belonged at each spot....

I see all of them when I open this thread, may wait and see if anyone else doesn't.

I just looked with IE and Chrome, pix not there

DaveO430 04-27-2015 04:26 PM

When I opened the tread this time they were in fact gone, I replaced them. Was going to put them in the gallery and post them from there but I can't find them in my computer and already deleted them from my camera.
