Brake cylinder sight glass

[reddirtrider]

GS750ESD - Has anyone replaced this on your bike, and if so, what did you use?

I found someone selling these for GS550's http://cgi.ebay.com/ebaymotors/suzuk...Q5fAccessories
and Katana's on Ebay, but they are glass. The old one is plastic and fits in a metal ring that appears to be pressed into the brake cylinder housing. I'm afraid the glass unit won't go in properly to seal.

Any suggestions appreciated.

Those glass ones are actually a watch crystal available from any supplier to the watch repair industry and you will have to seal it with some silicon rubber sealant and the metal ring will hold it in place.A while back I asked an ebay seller about sending to the RSA, but he never replied and I decided not to order and try it.

Might be just a little bit of work, but what I did is certainly cheap enough.

I got a tip from another motorcycle board, and cut out a piece of 1/8" Lexan. You can find sheets of this stuff at Lowe's, Home Depot, ACE Hardware, etc. for not a lot of money. Remove your old sight glass by whatever means necessary. Clean the hole impeccably with alcohol. Shape your piece of Lexan to fit the hole, but leave about 1/16" around the rim (the diameter of your Lexan will be about 1/8" smaller than the hole, but still larger than the ledge at the back). Mix up some quick-set 2-part epoxy, spread a bead around the ledge, place the Lexan disc into place, spread a bit more epoxy around the edge, forming a good seal. Wait until the epoxy cures, install the master cylinder, fill the system, bleed it, ride.

I'll check out the lexan - thx.

so how much pressure is exerted inside the reservoir anyway? I know that there must be a tiny bit but probably barely anything.

Probably not enough to worry about. I was curious how others attacked this issue. If I don't have to re-invent the wheel I won't. There's lots of experience here so I say 'use it'.

This is a great forum.

The only pressure on the inside of the reservoir is the liquid sitting in there.

In other words, virtually ZERO.

would be well worth a try. I fixed one one time. Just super cleaned and filled with JB. Sanded smooth

[Bribird]

I replaced the one on mine after I powdercoated the master...I just re-used the old metal ring and rubber gasket and removed the plastic one and used the watch crystal. No leaks..

Don't use arbitrary numbers like "zero" with me. You know I need something specific so that I understand! Wait, 0 is pretty specific isn't it? nvm



And btw Bribird, that looks killer. I'm jealous

Just for you, Mighty, I was going to go with "ZERO point something", but I wasn't sure exactly what the "something" was, so I just said "virtually ZERO".

Sorry about the uncertainty.

besides Steve, I don't believe that replacing the sight glass can be done anyway! I think you're going to have to take my MC and reservoir and replace it for me so that I'll believe you!! Yes... that's it, only will replacing mine for me make me believe!

[Steve]

Send it to me, include postage for the return trip, I'll do it for you.
