I finally got the master cylinder cap off my 1951 Ford by using the 3/4" drive 8" extension method, but the gasket has disintegrated. I scraped the remnants of the gasket off the cap per se, but a lot of the gasket stuck to the master cylinder. Is there some simple way to get the rest of the gasket off the master cylinder without getting any INTO the master cylinder. Thanks.
 
Not really. You will just have to be careful. You could use a sharp blade and always scrape towards the outside and maybe have a vacuum cleaner close by to encourage any bits to go away from the cylinder.

If you have a lathe you could turn a temporary plug to go inside the hole to stop stuff falling in. Maybe use one of those expandable plugs people use as a temporary freeze plug fix or when testing radiators.
 
If the master cylinder is that cruded up, it's probably time to remove it and refurbish it. These cars have single-circuit brake systems that should be kept in tip-top shape for your safety and that of others.

X-2 on tubman's comment. In addition I would inspect the entire brake system.

Siphon the fluid out with a baster, stuff a rag in and scrape away. There is no gasket on the newer plastic caps.

Just ordered a new one for my 50 model. Hope it's not to hard to put on.

Did mine this June. It's a pain. See the shoebox central youtube. Do you still have the rubber floor mat? If so it will be easier to get the inner fender cover off to access the clutch pedal bolt. Clutch shaft removal is tight. Loosen the M/C bolts first. Make sure you have full clutch pedal travel before install. I had to saw a piece off the M/C for clearance. Order new pedal bumpers while you are at it.

My 1951 is a Fordomatic; i.e., no clutch pedal. Do I need to remove the inner fender cover to replace the master cylinder?
