I have been looking for a rebuild kit for some time now for a 1985 Shadow VT1100C. Everyone tells me that they are unavailable. I was getting desperate to a point that I was ready to try and adapt another front brake master cylinder from another motorcycle.
I own a 84 Honda VF1100C V65 Magna. I got to wondering how close the master cylinders were to interchangeability so I took the Shadow brake cylinder to my Magna and was comparing them. They looked amazingly close except that the brake lever is at a different angle.
The more I looked, the more I got to thinking about it. BINGO
, Why not try a rebuild kit from the V65 Magna
The more I looked at it the better the possibility looked. They only made the V65 Magna for 4 years from 1983 to 1986.
Anyway, I ordered one on ebay and it came in today. I figured it would not hurt anything to have an extra one around in case I ever need one. IT WAS AN EXACT MATCH
. I had to re-use the check valve on the inside bottom of the spring, but that was no big deal. The part number for the Front Brake Master Cylinder is K&N MSB-103 Master Cyl Kit 32-1100. I got it on ebay from GMcycles. It may be available from others as well.
The SIGHT LENS was destroyed from the weather also. I bought one for the V65 Magna from a friend of mine with the user name of fingster. He is on the Honda bbsV4 forum by the name of BillyC. His lens kits come with the lenses for both the brake master cylinder and the clutch master cylinder, as well as new stainless mounting bolts to mount the master cylinders and new stainless screws for both caps.
Since the front brake master cylinder is the same, I suspect the clutch master cylinder kit is the same also.
This can be some helpful information for 1985-1986 VT1100C owners that have the same frustrations I had looking for the parts.
