I have a scooter I've been working on in the shop and today I went bleed the front brake. The fluid observation window on the reservoir was dirty so I went to wipe it off with a rag and the window crumbled. The scooter must have been sitting outside for a long time and the UV rays dismantled the molecules. The guy said he got it for free.
Anyway, after cleaning up the brake fluid that ran out I removed the reservoir and am wondering if I was to put some clear silicone on there or silicone a piece of plastic on there if the brake fluid will eat through the silicone. I know the reservoir isn't under pressure when you squeeze the lever so the only issue is will silicone stand up to brake fluid?
Thank you!

I really have no idea. I tried searching for you, but silicone brake fluid topics keep coming up.

I really have no idea. I tried searching for you, but silicone brake fluid topics keep coming up. EXACTLY! ARRRGH!  I went ahead and dug out the remainder of the brittle plastic and scuffed it up with some sandpaper around the edge, cleaned it again and filled the entire window with silicone and tooled it smooth. I'll fill it with brake fluid tomorrow and then watch it for a couple of days... If it doesn't work I'll install one of the three reservoirs I have out there but they all have a larger reservoir on them so I'll have to cut the opening in the plastic that covers the handlebars. Friggin hassle! This scooter has been on my bench for two days and every time I look at it I find a new problem. |

Update: The brake fluid has been in there for two and a half days and there's no sign of leakage. I'm glad because that means tomorrow I get $340 when I take the scoot back. Cha-Ching! $$$ ;D
That's not to say that the silicone won't fail in a few weeks or months so I'll be sure to tell the customer to keep an eye on it.

Yeah I bled the brake when I filled it a couple of days ago and I rode it a bunch hitting the brake hard today and it stops well.

I was re-reading all my old topics and I came across this one. I never tried the experiment Goosey suggested for some reason but I'm gonna do it now cause it deserves the research cause it's a great idea. Thanks again Goosey!  Maybe I should do it with several jars and several different types of silicone... I never got a call back so I guess the repair worked or he died a fiery death when the fix failed. :dunno: |

I supose the master cylinder has rubber seals in it so could be a good fix, it does not eat the rubber. |
