Re: 1100 GS front Master Cylinder

[Dean Wegner <deanwegner@xxxxxxxxx>]

The Master Cylinder on my RT started to not hold pressure.  It would slowly pull all the way back to the bar.

A rebuild kit from the local dealer with a little honing inside the cylinder took care of the problem.

I would say the stickyness is just corrosion built up inside the bore and at the pivot points.  It needs to be cleaned out.

Mine has been good ever since.
