If you are sure that you have all of the air out of the system, and if your '62 has its original backing plates and adjusters, it is possible that the adjusters are worn, and "backing off" after a couple of applications of the brake pedal. It will be easy to know if this is true by checking the adjustment again. If they aren't the way you left them after the previous adjustment, you may need to rebuild/replace the backing plates. Just one idea of many possibilites, but easy to check.

Subject: IML: Dual Master Cylinder Install - 62 Imperial Pedal of Doom Part III
Hi to All: I Spoke of My Dual Master Cylinder Conversion Earlier. The Problems with A Bad Newly Rebuilt M/S & Cleaned Up "Old" Brakes Shoes - The Ones the Bled Out Grease + Brake Fluid When the Got Warmed Up are Solved. With Brand New NOS Shoes On the Rear & Another Newly Rebuilt Master Cylinder On, I Made Sure it Was OK by Bleeding it Out & Dead Heading it (Blocking off the Ports & Standing on it). It's Rock Hard. I Connected Up the Rear Brakes, Bleed Them Out & They Are Rock Hard. NOW I Pipe up the Front, Bleed Them Out (Very Good) & Pipe Them Up Now a Soft Pedal ! Any Ideas. HELP Again.
Thanks & Happy Imperialing
