Re: {Chrysler 300} Re: 62 H brake master cylinder

Replaced master cylinder in my 300F. 

There is a brass adapter that connects the brake line to the cylinder - and it’s leaking - with fluid coming out of the adapter threads on the cylinder side. 

The adapter appears to not be as deep as the seat in the cylinder - and the only thing sealing the connection are the threads themselves.

Where can I get the correct adapter?

Agree with Nick.  I recently was looking for break components for my ‘64 Imperial which also has a single reservoir master and 8” dual tandem booster and found what appears to be the a number of single reservoir masters that should work on the 300H:

Good luck!

Anyone have a source for these?  NAPA and Rock Auto seem not to carry them any longer.
