Title: Aftermarket Front Master Cylinder
Post by: Iarn on February 21, 2015, 08:04:02 PM
Looking for an aftermarket or direct swap from other model motorcycles for the front brake master cylinder container. No levers, nor switches. All that I still have.

I broke a screw off in there that is impossible to get out. OEM replacement from Bikebandit is very expensive and the current selection of OEM reservoirs on Ebay doesn't seem very good.  Any workable suggestions for replacements?

I was looking at this http://www.ebay.com/itm/Universal-Motorcycle-Master-Cylinder-Fluid-Oil-Reservoir-Front-Brake-Clutch-Tank-/281313951325?pt=Motorcycles_Parts_Accessories&hash=item417f9e3e5d&vxp=mtr (http://www.ebay.com/itm/Universal-Motorcycle-Master-Cylinder-Fluid-Oil-Reservoir-Front-Brake-Clutch-Tank-/281313951325?pt=Motorcycles_Parts_Accessories&hash=item417f9e3e5d&vxp=mtr) but i'm not sure it comes with all the attachments it needs to fit on a GS500. Also, does reservoir capacity matter at all?

I just bought one of these, it hasn't come yet but I started a thread wondering where I can plug the s brake light wire because it plugs into the reservoir, at least on my 92 gs.  but heres the link

The replacement resevoir is about 1/2 to 1/3 smaller than the OEM master cylinder. Could this be an issue? Does the brake fluid resevior size particularly matter?

Nah..keep an eye on it, as the pads wear it will go down quicker because of it's size.

Thanks Stevo, I was worried about it. I'll be glad to have brakes after she's been sitting in my garage for a week.
