I was going change and flush the brake fluid in my '97 limo since the fluid looks like coffee and has probably never been changed. After sucking the old fluid out there is a lot of sediment on the sides of the reservoir. I may be able to clean the front section with a q-tip but not the back one. How hard is it to get the reservoir off the master cylinder to fully clean the back chamber? It just looks like pressing out 2 roll pins and disconnecting the fluid level sensor.

I think that is about all that is required.

Yea, I got it off. Now how to get the crud off the inside. I was thinking of pouring in a tablespoon full of BB's along with a few sprays of brakeclean and shaking the crud loose. Any better ideas?

Sounds as good as anything I can come up with.
