Re: New Member - Help with disassembly of Power Brake Unit

Posted by BH On 2007/4/6 11:55:37

IF you have disassembled the unit per the factory shop manual (which was the first thing that BigKev uploaded to the site, under "Packard Articles"), the seals could just be stuck after decades of co-mingling in the master cylinder bore.

Soak 'em down with some WD-40 and let sit overnight. I bet that will loosen 'em up just enough. If not, try a good penetrating oil, and wait about 15-20 minutes.

P.S. - Thanx for the nice pic of your '53 - and taking time to add it to the Owner Registry here.
