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?
