Front Master Cylinder Level Glass Leaking

[Anonymous]

On my 85 GS1150 the front master cylinder level glass has a leak. Can these be replaced?

How big is the leak and where is it located? Could you seal it from the inside with a clear epoxy or superglue after you draw down the brake fluid level? Of course the brake fluid may gradually dissolve this coating over time, but might be worth a shot and save you time and replacement hassles. Best regards...

superglueing it wont work.....brake fluid will eat it in no time. Possibly the epoxy , or some sort of silicone may work. However, whatever solution you find, you must make sure that it forms a perfect seal around the glass, or your just letting in dirt, water, and air into your brake fluid/lines (bad stuff).

The worst case is getting a new master cylinder reservoir. its a pain in the ass, and for me cost around 45 bucks cdn.

two ways to fix it without replacing it. First- remove the window and fill the hole with JB weld, 2th get a piece of plexiglass rod of the correct dia and cut a piece to fit the hole and polish the ends

I've heard of a machinist who could make a disk out of aluminum to replace these windows. I'm not sure how he reatined and sealed the disk, or who it was, or if it's even true, but it's something to think about.

Thanks for all the advice. I ended up taking a 1/8" thick piece of plexiglass to a glass shop. They cut me a piece the size of a dime. I used JB weld to insert the plexiglass.
Good as new now.
