Maybe the line that goes to the rear brakes is pinched or plugged. Could also be a blockage in the port for the rear brakes in the master cylinder.

I had this happen to a Mustang once...I discovered that the brake line ran INSIDE the car, then under the rear seat, then out the floorpan. The rubber grommet had cracked, allowing water to collect under the seat, soaking the sound insulation like a sponge. The brake line was totally rusted through. I couldn't find the leak, because it was INSIDE the car, and the insulation was soaking up the brake fluid.

Could be what's happening to you. Follow the brake lines.

We'll start with the master cylinder. Check for leaks, this includes looking at the firewall INSIDE the car if the master bolts directly to the firewall. Pull the vacuum line from the power booster and check for break fluid. (you can see it, also smell it) No problem .... step two, check the lines to the wheel cylinders/calipers for leaks, kinks or flat out breakage. now open a bleeder valve on one of the breaks and have a friend (with the engine off) press the break pedal, watch to see if break fluid squirts out. No fluid squirting, no kinks in the line. Make sure you have fluid in the master cylinder. If you have fluid, loosen one of the lines at the master cyln and have that friend again step on the breaks, you should see fluid leaking out around the lose fitting, if not, it master cyln time.
This is a way to check out the break system, if it work at one end but not the other, the problem is in between.

Sounds like you could have a leak. Possibly a blocked line or a bad master cylinder.

I'd have it looked at by a good mechanic.

There is obviously a blockage or a leakage somewhere.
