Look for pinch line or colapssed hose allowing fluide to go true under pressure from pedal
but creeping back out due to restriction if you crack open the bleeder screw on the problem
wheel fluide should spurt out and brakes would release also a bad master cylinder can cause this

1975 cadillac coup deville acts like brakes or parking brakes are locked up engaged. In a bind and will barely move in gear. parking brake pedal is up in the disengaged position. Help?

It is not unusual for the parking brake cable assembly to seize due to corrosion. Also, the rear brakes are self-adjusting when backing up and can eventually wind up by themselves until they lock up. Start by removing the rear wheels and checking the brake shoe assemblies. Due to the age of the vehicle, this can be quite a chore, as the brake adjuster may have to be manually backed off before the brake drums will come off. Also, if the brake cable is seized, you may have to remove/manually loosen it as well. It is a part that needs lubricating periodically so it works freely, and may need to be replaced.

Brake line diagram

What you need to do is take off the original line. If you check on the Web, you may find some kits for a complete system, but an individual line is often difficult to ship.

There are different size fittings on the ends of brake lines. In some cases, the Universal lines may work, but the end fittings must match your vehicle. This is why taking the old line with you is important.

Some mechanics get coils of brake lines and bend and fit the ends themselves. It takes a few specialized hand tools to accomplish this. They are not terribly expensive, but for 1 line it is not worth it and it takes some skill to properly install the fittings on the line.

Now you have a 14 Year old car, and I can't recall when they stopped all production. But even a later model may be too old for them to stock a Factory replacement part.

A good brake shop would be your best bet. Call ahead and ask if they can make a line to replace what you have. It should not take but a 1/2 hour or so to swap out what you have, then some time to bleed the brakes.

One thing to consider- ALL lines were new at the same time. If one rusts out, there are few reasons for corrosion to be any worse for the failed line than the rest of the lines on your van. The exception would be collision replacements in which some brake lines might be newer than your van.

Brakes Locking

I suspect corrosion in your master cylinder, or in one or more wheel calipers. That usually happens when the brake fluid gets old and absorbs moisture.

How long would it be since the brake fluid was flushed and replaced?

After starting engine and shifting to reverse or drive, the van can not move, because one of the wheels is still in locked for some reason (parking brake is off). The locking happens when the van parks...

This is not really a weekend mechanic type job a more delicate operation that needs a proper trained mechanic to locate and repair the problem,i think it may be a seized wheel cylinder or a sticky caliper and without stripping it myself and having a good look myself i wouldnt know so you will have trust your local mechanic to do it for you

A light came on in my van it is the (P)with an!mark right above it,I know it is the emerg brake light but my brakes seem to be fine, and the light will come on then go off has happened a few times...

This may indicate that your rear brakes are wearing out.

Go somewhere and have the rear brakes checked for run out.

Rear brake service is usually reasonably priced. Your van is old enough that it might be overdue for new shoes and some drum machining.

Good luck and be careful.

Vibes have had a number of problems, so this could be one of them. These brake systems are ultra-sensitive to contaminated brake fluid - make absolutely sure they completely flushed the system and replaced the brake fluid when they replaced the master cylinder.
