Can you disconnect and plug the vacuum line and then drive
the car as is ? Pedal will require a bit more effort, but you'll have
able-bodied folks at the meet that can fix the problem (and possibly swap out
the booster). Just a suggestion.

Problem
is the booster itself. So trying to locate one, or head back home very
carefully. Can unlock by uplifting brake pedal. Have to pass on this meet. Try
for fall in Wisconsin. About 200 miles closer to home! Thanks for all the
quick suggestions.

Lindsey,
Where are you, geographically, right now? Perhaps
we have a Club member in the vicinity who can help.

Scooter465:
That would be true for a master cylinder attached to a firewall
mounted brake booster, a combination used since 1962. But I believe
the 300F uses a remote booster and manual brake style master cylinder bolted
directly to the firewall, because of clearance issues with the ram
tubes.

How about the pushrod length adjustment can cause brakes to drag if it
is adjusted to long brakes heat up and lock up.

I have experience a rubber hose
failure where internal degradation creates a check valve effect that
prevents the brake from releasing when the pedal is released. The
age of rubber hoses is not measured in miles, it is measured in years.
How long ago did you replace those hoses? They can look fine
on the outside but still fail on the inside. A single hose failure
would cause a problem only with the wheels controlled by the suspect hose,
not all at once. This is just one possibility, you may have
something else going on if all wheels or both fronts together lock
up.

For sure fronts.
Don't about rears. Single master cylinder system. Rubber lines to wheels
probably 4000 miles max. No cracks. I did just notice the old style hose
clamp from the proportioning? Valve to the reservoir had slipped away from
the valve, so maybe vacuum leakage? But y not all the time? Wud just have
no power boost? Pedal normal pressure otherwise

Are all four
wheels locking up, or just the two rear, or one or both fronts? How
old are three rubber hoses, one between the wheel cylinder and metal brake
line on each front wheel and one between metal line of body and metal
lines on the rear axle housing?

My brakes have absolutely seized up twice today, both times from
about 25-30 mph. Luckily I didn't get rear ended. Seems like a booster
issue as nothing binding in the pedal mechanism. First time stalled the
car. Restarted and not locked. Second time I think I caught the side of
pedal with my foot and it released. Both times gentle braking. The locked
solid. I am in St. Paul minnesota. Anyone know of someone in the area
that might be able to help? Or ideas to solve the issue?
