I believe it was the brake booster that went bad.

Hi! Thanks for reminding me! - I had a Simca 1501 estate many , many , moons ago , and the brakes locked on after applying the footbrake , reason ; the diaphram had split in the servo , jamming the piston in the on position , the only way I could move forward was to stop the engine , pump the brakes to remove all of the vacuum and this would allow the brakes to release. - cured by replacing the diaphram , - you could do that sort of thing then .
