Front MC

[thefast1]

Have an 82 GS1100EZ and the front MC when applying the front lever I hear a hissing sound, so I'am looking for a rebuild kit for the MC, anyone know of where I might find this

If we can assume that the hissing sound occurs when brake is applied while moving it is probably the sound you get from slotted discs. The master cylinder won't make any noise on it's own that I am aware of.

Z1Enterprises.com may carry them. Do yourself a favor if you have the funds, and since you'll basically have to tear the system down anyway, rebuild and clean your calipers and replace the lines with stainless (available at Z1 as well). Massive difference in braking performance.
Take care to inspect the bore for pitting/scoring. If it has it, it's trash. Also assure you clean the tiny pressure return port out as well.
Good luck!

Original suzuki brake system parts are highly recommend. Aftermarket K&L brake parts, as sold by places like Z1, are crap in comparison.
