Grandpa’s 504: hydraulics

This happened in between the last installment in the series.

Both the brakes and clutch didn’t work (besides not having fluid, the cylinders were stuck) so I set up to dismantle them.

After some contortions I managed to free the mechanism. A couple of hard lines broke around the fittings and part of the servo assist snapped while I was pulling.

The air filter in this unit is an oil bath one and was perfectly full. After draining it I used lots of gasoline, kitchen cleaner and boiling water to remove every trace of grim and oil. But now the filth migrated to the sink.

I also removed the valve cover to take a peek inside. It looks surprisingly clean and neat for a car of this age. The gasket was torn apart, that may explain the amount of oil on the block.
