I just bought an '83 front master cylinder for my '82 GL1100, '82 one had a cap screw busted off in it and leaks all over the place. The new one would not build pressure, lever comes all the way back to the handlebar (properly bled and all other components completely checked out) it only offers about 20% front brake.
Not knowing there was a difference between the 2 year models I ordered an '82 model rebuild kit, while I was waiting I put the '82 back on and it and apart from it leaking like a stuck pig, it worked fine, when thekit arrived it was obvious it was of a wider diameter than the cylinder I was trying to fit it into, soI did some research and found out about the difference in the 2 year models, sent it back and got the right one for the '83 master cylinder that I had, that didn't leak, fitted the smaller kit and it fits great.
This eveninga friend and I set about bleeding this thing and lo and behold, we gotexactly the same result, all the way back to the bar and 20% brake.
My questions to you guru's are these:- Does the smaller diameter of the '83 make it impossible to build sufficient pressure to operate with '82 equipment? Or, do I just have a damaged '83 cylinder? It for sure looks smooth inside there, Have any of ya'all ever even had this problem?I sure would like to hear any input you guys can give me, thanks.
For what it's worth and if I may be so bold? The current rebuild of the `80, `81, `82 & `83 GL1100STDASPENSTATE can be followed on classicgoldwings.com in a thread called "The plan is to turn 140,000 into 50,000."
