MC54-250B Brake Master Cylinder

[scooterdad154]

I have a 2008 MC54-250B with about 10200 miles on it.
The plastic circular window on the side of the front brake fluid reservoir is cracked.
I actually put my thumb through it by accident. (I was at a stoplight and the front brake felt lever had more travel then normal. I went to look through window to see fluid level but it appeared dirty so I tried trying to rub dirt off of it. My thumb went right through the window. It must have deteriated by the sun.)

Is there a way to replace the plastic circular window or should I just buy a replacement master cylinder?

Could I remove the damaged plastic and use clear epoxy to form a new window?

Thanks
Jim

I have heard that it is possible to fix this but I would find a new master cylinder that matches and replace it. I replaced mine for $30 but it might not be the same as yours. Got mine at Scrappydogs.

If you buy a master cylinder make sure you get one with threads for your mirror.

Fill the window with silicone. $1.99 for a tube of RTV
